This document discusses bioethanol production from liquid waste of cashew and cocoa plants at the Institut Teknologi Sepuluh Nopember in Surabaya, Indonesia. It describes the pretreatment, fermentation, and distillation processes used to produce bioethanol. Test results showed the bioethanol produced had an ethanol level that made it suitable for use as fuel in bioethanol stoves. The institute has worked to promote bioethanol production and use, including producing the first bioethanol stove in 2008, constructing large-scale fermentation and distillation equipment, and partnering with local governments and media outlets.

It is great privilege doing my Student Industrial Work Experience with HarvetPlus Nigeria C/O International Institute of Tropical Agriculture (IITA), Ibadan. A huge some of practical knowledge and experience was imbibed in me for a period of six months working with HarvestPlus C/O IITA. With the mentorship and supervision of Dr. Paul Ilona (HarvestPlusCountry Manager), i was thought the relevance of biochemistry in the research institute. Working under HarvestPlus, I was exposed to different laboratories such as the Virology and Molecular Diagnostic Lab, Tissue Culture Lab, Biochemistry Lab and Microbiology lab. It’s no doubt that biochemistry as a field of study is best practiced and applied in a research organization like HarvestPlus C/O IITA because the institute is sited in good learning environment with lots of sophisticated equipment and machineries. I was given the opportunity to participate in the on-going research program on biofortification of crops with micronutrients leading to the discovery of Vitamin A Cassava and its retention during processing. Moreover, I also had the opportunity to work with few Scientists and Research Fellowship Students who shared their various knowledge and experiences with me. I also had the opportunity to exchange knowledge with other biochemistry students from different Institutions also doing their Industrial Work Experience.

Bioethanol production from fruits and vegetable wastes

archana janamatti

Attention towards natural growth promoters in poultry has been on the increase in different parts of the world. However, most studies focus on broiler birds and quail. This study analyzed how cinnamon powder supplemented in the diet of Lohmann Brown layer birds can improve egg quality. This study consisted of 5 treatments of 30 birds per treatment, comprising fifteen replicates of 2 birds per replicates. The treatments included: T1: Control without Cinnamon; T2: 4 litres of water + 0.1g of cinnamon; T3: 4 litres of water + 0.2g of cinnamon; T4: 4 litres of water + 0.3g of cinnamon; T5: 4 litres of water + 0.4g of cinnamon. Parameters measured were egg weight, egg mass, egg breadth, egg length, albumen height, albumen weight, yolk height, yolk length, yolk colour, yolk weight, shell weight, and shell thickness. The results revealed an increase in the albumen weight, yolk weight, albumen height, and yolk height as the inclusion levels of cinnamon powder increase. In addition, the egg weight was highest in treatment 5. Taken together, cinnamon powder addition in the diet of Lohmann Brown layer birds has a positive outcome on egg quality.

Protein Extraction and Purification of Soybean Flakes and Meals Using a Lime ...

IJMER

Protein extraction and purification by lime treatment and ultrafiltration on soybean flakes and meals is an environmentally friendly process that promises a novel alternative to conventional chemical treatment methods. Protein was extracted from soybean flakes and meals by ionic-strength of lime as alkali treatment. After centrifugation, proteins were purified by ultrafiltration.Lime treatedflakes and meals showed significantly higher level of dissolved solid, protein, and carbohydrate extraction rate than conventional sodium hydroxide or water treatment. Soybean flakes represented a higher extraction rate of protein and carbohydrate than meals. This result may becauseby extensive cell distortion and disruption with cracking, cooking, and flatting which allow lime solutes to easily permeate the cellular matrix. Ultrafiltration substantiallypurified the protein with minor loss of yields, 94.42% and 96.79% for soybean flakes and meals, respectively. Therefore, lime treatment and ultrafiltration is a viable option for extraction and purifying proteins of soybean flakes and meals

Immobilization of two endoglucanases from different sources

IJEAB

Cellulases are a important family of hydrolytic enzymes which catalyze the bond of cellulose and other related cello-oligosaccharide derivates. Industrial applications require enzymes highly stable and economically viable in terms of reusability. These costs can be reduced by immobilizing the cellulases, offering a potential solution through enzyme recycling and easy recovery. The covalent immobilization of enzymes is reported here: one is commercial cellulase from Aspergillus niger and other one is recombinant enzyme, named CelStrep it because was isolated from a new cellulolytic strain, Streptomyces sp. G12,. The optimal pH for binding is 4.6 for both cellulases and the optimal enzyme concentrations are 1 mg/mL and 5 mg/mL respectively. The support for immobilization is a poliacrylic matrix. Experiments carried out in this work show positive results of enzyme immobilization in terms of efficiency and stability and confirm the economic and biotechnical advantages of enzyme immobilization for a wide range of industrial applications.

IJERA Editor

Production of biofuel such as ethanol from lignocellulosic biomass is a beneficial way to meet sustainability and energy security in the future. The main challenge in bioethanol conversion is the high cost of processing, in which enzymatic hydrolysis and fermentation are the major steps. Among the strategies to lower processing costs are utilizing both glucose and xylose sugars present in biomass for conversion. An approach featuring enzymatic hydrolysis and fermentation steps, identified as separate hydrolysis and fermentation (SHF) was used in this work. Proposed solution is to use “pre-processing” technologies, including the thermal screw press (TSP) and cellulose-organic-solvent based lignocellulose fractionation (COSLIF) pretreatments. Such treatments were conducted on a widely available feedstock such as source separated organic waste (SSO) to liberate all sugars to be used in the fermentation process. Enzymatic hydrolysis was featured with addition of commercial available enzyme, Accellerase 1500, to mediate enzymatic hydrolysis process. On average, the sugar yield from the TSP and COSLIF pretreatments followed by enzymatic hydrolysis was remarkable at 90%. In this work, evaluation of the SSO hydrolysate obtained from COSLIF and enzymatic hydrolysis pretreaments on ethanol yields was compared by fermentation results with two different recombinant strains: Zymomonas mobilis 8b and Saccharomyces cerevisiae DA2416. At 48 hours of fermentation, ethanol yield was equivalent to 0.48g of ethanol produced per gram of SSO biomass by Z.mobilis 8b and 0.50g of ethanol produced per gram of SSO biomass by S. cerevisiae DA2416. This study provides important insights for investigation of the source-separated organic (SSO) waste on ethanol production by different strains and becomes a useful tool to facilitate future process optimization for pilot scale facilities.

Asheesh Padiyar

Bioethanol can be used as a second generation advanced biofuels. Currently it is mainly produced from starch but bioethanol production from starch leads to competition for food, land and price. Therefore, ligno-cellulosic agricultural residues are potentially used for bioethanol production to solve such challenges. In the present work acid pretreated tamarind kernel powder is used as a ligno-cellulosic biomass for bioethanol production using marine yeast. Greater osmosis tolerance, greater special chemical productivity and production of industrial enzymes are the unique characteristics of marine yeast over terrestrial strains. Hence, marine yeasts have great potential to be applied in various industries. Therefore, the marine strain of saccharomyces cerevisiaewas isolated from marine water and was used for bioethanol production and the bioethanol yield was optimized using the full factorial design methodology. The amount of Bioethanol yield on day 2 was found to be 2.3g/l and the interaction effects were also studied using Minitab 17 software.

Fibrous Scaffold Produced By Rotary Jet Spinning Technique

IJERA Editor

Poly(L-lactic acid) (PLLA)/ poly(ɛ-caprolactone) (PCL) mesh was produced by Rotary Jet Spinning (RJS) process. RJS is a simple method which fabricates three-dimensional fibers by exploiting a high-speed rotating nozzle o form a polymer jet which undergoes stretching before solidification without the need of high voltage. Blend meshes were characterized by scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), differential scanning calorimeter (DSC) and infrared spectroscopy Fourier transform (FTIR). SEM imagens provides information about the morphological structure, which confirmed the production of fibers using RJS. Data obtained by thermal analyzes indicated the immiscible property of PLLA/PCL blend and also the total solvent evaporation. As a preliminary in vitro assay it was investigated using Vero cells, was not found any sign suggesting cell toxicity, indicating biocompatibility. Thus, this report suggests the use of PCL/PLLA mesh as fiber scaffold substrate for tissue engineering

Cancer cell metabolism: special Reference to Lactate Pathway

AADYARAJPANDEY1

Normal Cell Metabolism: Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released. Cell utilize energy in the form of ATP. The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process. Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP. The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos). It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation. If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use. IN CANCER CELL: Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful. Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation. This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive. Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful. Cancer cells only partially break down sugar molecules.

This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive. introduction to WARBERG PHENOMENA: WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside. Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme. WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

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.

Sérgio Sacani

The ambient solar wind that flls the heliosphere originates from multiple sources in the solar corona and is highly structured. It is often described as high-speed, relatively homogeneous, plasma streams from coronal holes and slow-speed, highly variable, streams whose source regions are under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify solar wind sources and understand what drives the complexity seen in the heliosphere. By combining magnetic feld modelling and spectroscopic techniques with high-resolution observations and measurements, we show that the solar wind variability detected in situ by Solar Orbiter in March 2022 is driven by spatio-temporal changes in the magnetic connectivity to multiple sources in the solar atmosphere. The magnetic feld footpoints connected to the spacecraft moved from the boundaries of a coronal hole to one active region (12961) and then across to another region (12957). This is refected in the in situ measurements, which show the transition from fast to highly Alfvénic then to slow solar wind that is disrupted by the arrival of a coronal mass ejection. Our results describe solar wind variability at 0.5 au but are applicable to near-Earth observatories.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.

Sérgio Sacani

The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
