This document discusses several types of fungi:
1. Saprophytic fungi break down dead organic matter and play a key role in nutrient recycling. They produce enzymes that break down materials like cellulose, hemicellulose, and lignin.
2. Parasitic fungi infect and feed off living hosts like plants and humans, causing diseases. Major groups that cause plant diseases include powdery mildews, downy mildews, and smuts.
3. Coprophilous fungi feed on dung and help disperse spores through herbivore digestion. Their spores can survive passing through the gut before germinating in dung.
4. Keratinophilic fungi break

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

3. SAPROPHYTIC FUNGI
• The word saprophyte is derived from the Greek words “Sapros” and “Phyton” which
means putrid and plant respectively .As such its concerned with decaying plant
matter.
• Fungi which obtain their nutrients from dead organisms and these are mainly
responsible for recycling the components of dead plants are known as saprophytic
fungi.
• They obtain food by dissolving organic material
• CHARACTERISTICS : They are eukaryotic ,lack chlorophyll and non vascular , produces
enzymes (cellulase, phytase,lipase etc),found in dark /shady and moist habitat.
KKR1116 3
5. IMPORTANCE OF SAPROPHYTIC FUNGI :
• They are the primary recyclers of nutrients.
• They break down organic matter so that the nitrogen ,carbon and minerals it contains
can be put back into a form that other living organisms can take up and use .
• They release enzymes to break down and digest the lignin,cellulose or chitin into
simple soluble compounds that can be absorbed by them and plants as nutrients.
• HUMUS FORMATION: Saprophytic fungi play a vital role in the formation of of brown or
black organic complexes which remain in dynamic state.Humus can be fractioned into
HUMUS , HUMIC ACIDS , FULVIC ACIDS and HYMETAMELANIC ACIDS.
• Aspergillus and Penicillium are the genera involved in the degradation of humic acid.
KKR1116 5
6. TYPES OF ORGANIC COMPOUNDS DECOMPOSED BY SAPROPHYTIC FUNGI:
1.CELLULOSE STRUCTURE AND ITS DECOMPOSITION :
• Cellulose is an organic polymer consisting of linear chains of ß-D-glucose units and
are linked by ß(14) glycosidic linkages.
• Two ß-D-glucose units linked by ß(14) glycosidic linkage forms a disaccharide
called cellobiase. The cellulose are connected by hudrogen bonds and forms tightly
packed crystals . Cellulases hydrolyze the ß(14) glycosidic linkages of cellulose.
• Endoglucanases : hydrolyze internal bonds releasing new terminal ends .
• Exoglucanases : act on the existing or endoglucanase generated chain ends .
• Both enzymes release cellobiase molecules .
Eg, Pleurotus ostreatus , Pleurotus florida , Fusarium solani, Aspergillus niger etc
KKR1116 6
8. 2. HEMICELLULOSE STRUCTURE AND ITS DECOMPOSITION :
• Hemicellulose belongs to a group of heterogenous polysaccharides.
• These polysaccharide contains many different sugar monomers which include xylose
,mannose ,galactose ,arabinose rhamnose, glucuronic acids and galacturonic acids.
Sugars are linked by ß1,4 and occasionally by ß1,3 glycosidic bonds.
• Hemicellulose helps in strengthing the cell wall by interaction with cellulose and in
some wallas with lignin.
• Hemicellulose devided into 2 categories –
Homoglycans – single monosaccharide type .eg- xylan ,mannan
Heteroglycans – more than one kind of monosaccharide .eg-glucomannans
,arabinoxylans.
KKR1116 8
10. • Decomposition of hemicellulose involves 3 types of enzymes :
Endo –enzymes : which randomly cleaves the bonds between building blocks in the
polymer .
Exo-enzymes : cleaves either a dimer or monomer from the end of the
polysaccharide chain.
Glycosidase : which hydrolyzes the oligomers or disaccharides produced from
hemicellulose
• Examples of utilizing hemicellulose are species of Alternaria, Aspergillus , Fusarium ,
Penicillium etc.
KKR1116 10
11. 3. LIGNIN STRUCTURE AND DECOMPOSITION :
• Lignin is a complex polymer of 3 kinds of aromatic alcohols bonded by three types of
bonds which are aryl,ether,and ester which provide lignin a three dimensional polymer
of intermediate size.
• Lignin +cellulose =lignocellulose
• Lignin derived molecules have long been considered to be of significance in the
formation of humus which is important in maintaining soil fertility.
• Decomposotion of lignin is brought about almost entirely by fungi and especially
Basiodiomycetes such such as members of Aphyllophorales and Agaricales .
• Lignin can be slowly degraded by white –rot fungi such as Phanerochaete
chrysosporium which produce an extracellular lignin peroxidase enzyme to commence
the degradation process.Others fungal strains produce manganese peroxidase and
Laccase enzymes that are also active in lignin breakdown .
KKR1116 11
14. PARASITIC FUNGI
Parasitic fungi attack living organisms ,penetrate their outer defenses , invade them
and obtain nourishment from living cytoplasm thereby causing disease and
sometimes death of the host .Most pathogenic fungi are parasites of plant .
They enter the host through a natural opening such as stoma in a leaf , lenticel in a
stem or a wound in the plant .
Common diseases of plants caused by fungi mildews (eg, grapes ,onion ,tobocca) ;
the smuts (eg, corn ,wheat ); apple scab; brown rot of stone fruits and various leaf
spots , blights and wilts.
Major groups of fungi and the disease caused :
Perosporaceae – downy mildews
Erysiphaceae – powdery mildews
KKR1116 14
15. Downy mildews of grapes – Plasmopora viticola
The smuts of corn – Ustilago maydis
KKR1116 15
16. Ustilaginales –smuts
• Other groups include hymenomycetes, certain ascomycetes and particularly
deuteromycetes .
• OBLIGATE PARASITE – Those parasite which grows only on living tissues .Nowadays
pathogens of plant have been divided into 2 broad categories:
OBLIGATE PARASITE
BIOTROPHIC PARASITES NECROTROPHIC PARASITES
They derive their nutrients They derive the nutrients from
from living host cells. dead host cells , usually killed by
Eg, The rust fungi(basidiomycetes) the parasite in advance of
The powdery mildew( ascomycota) penetration. Eg, Botrytis cinera
causes grey mold
KKR1116 16
18. • INFECTION PROCESS: Spores of a pathogenic fungus falls on the leaves /stem of a
susceptible host germinateseach spore producing a germ tubetube grows on the
surface of the host until it finds an openingtube enters the host mycelial network
is formed within the invaded tissue.
• The germ tubes of some fungi produce special organs called appressoria from which a
needle like peg presses against ounctures the epidermis of the host after penetration ,
a mycelium develops .
• Many parasitic fungi absorb food from the host cell through the hyphal walls apressed
against the cell walls of the hosts internal tissues and others produce haustoria.
KKR1116 18
19. FUNGI AS HUMAN PATHOGEN
• Fungal infection is caused by mold yeasts.
• A disease caused by a fungus on human and animal is called Mycosis. Mycosis are
frequently named after the part of body attacked.(eg, Bronchomycosis for respiratory
tract , Dermatomycosis for skin).
• Pathogens are categorized into 4 categories :
SUPERFICIAL - only the outer surface of the skin is invaded .
CUTANEOUS – where the keratinized tissues of the body are invaded.
SUBCUTANEOUS – where invasion occurs in the deeper layer of the skin, extending
into muscles, sometimes into the bone and may involve the lymphatic system .
SYSTEMATIC- where infection of lungs takes place by direct inhalation of fungal
spores . Infection may spread to all organs of the body and may cause death of the
host.
KKR1116 19
21. FUNGI WHICH ARE ABLE TO INVADE HUMAN TISSUES ARE DIVIDED INTO TWO
GROUPS:
• THE PRIMARY PATHOGEN : they are capable of producing special kinds of fungak
infection in healthy individuals and have special clinical characteristics.
• THE OPPORTUNISTS : they will only invade the tissues of compromised host .
KKR1116 21
22. COPROPHILOUS FUNGI
• They are a type of saprobic fungi that grow on animal dung.
• The distribution of coprophilous fungi is closely linked to the distribution of
herbivores on which they rely such as rabbits ,deer,cattle,horses and sheep.
• The hardy spores of coprophilous species are unwittingly consumed by herbivores
from vegetation and are excreted along with the plant matter. The fungi then
flourish in the feces before releasing their spores to the surrounding area.
• Coprinus radiatus & Panaeolus campanulatus grow exclusively on horse feces.
• Panaeolus sphinetrinus can grow on any feces or even just particularly fertile soil.
KKR1116 22
24. • Chaetomium globisporum grows on dung of omnivores (rat droppings )
• Chaetomium rajasthanense grows on dung of carnivores (tiger feces)
• PROCESS: Coprophilous fungi releases spores into the environment eaten by
herbivoresplant digested passes through the animal’s
intestinesdefecatedfruiting bodies of the fungi grow from animal feces the
spores of the species then reach new plant material .
• Some species have developed means of discharging spores a large distance.
Eg, Genus – Pilobolus ; fruiting bodies of Pilobolus will suddenly rupture sending the
contents over 2 metres away.
• Animal feces provide an environment rich in nitrogenous material as well as various
enzymes from the animal’s digestive system.
• The spores themselves survive digestion by being particularly thick walled ,allowing
them to germinate in the dung with minimum competition from other organisms.
• The thick wall is often broken down during digestion ,readying the spore for
germination.
• Eg, Pilobolus kleinii, Mucor hiemalis, Sordaria fimicola
KKR1116 24
26. KERATINOPHILIC FUNGI
• Various keratinophilic fungi along with some dermatophytes are responsible for
various skin infections .
• The most active keratinophilic fungi are dermatophytes and their correlates especially
–Microsporum, Trichophyton, Aphanoascus.
• In the kingdom Eumycota (true fungi ), two groups – Deuteromycetes & Ascomycetes
have keratinolytic members that occur commonly in soil as keratin decomposers.
• Some species are potential pathogens and can cause infections in the skin and scalp of
mammals (the dermatophytes)
• Keratinophilic –exhibiting affinity for keratin (as in hair,skin,feathers or horns) used
chiefly of fungi capable of growing on such materials .
• The biological function of keratinophilic fungi in the soil is the degradation of
keratinized materials such as hides, furs ,claws , nails, and horns of dead animals.
• In the soil these fungi live in their teleomorphic (=sexual) stages in the form of
cleistothecia , whereas in keratinized material ( host )they live in an anamorphic
(=asexual) stage .
KKR1116 26
27. • Multiply asexually by producing enormous number of conidia and sexually by means
of fruiting bodies called ascomata ( when the keratin substrate is depleted )
• Eg , Chrysosporium spp ( mainly Chrysosporium indicum , Chrysosporium tropicum,
Chrysosporium keratinophilum)
KKR1116 27
