The document discusses biodegradation, bioremediation, and bioaugmentation. It defines biodegradation as the breakdown of organic matter by microorganisms. Bioremediation uses microbes to transform contaminants into non-toxic products. It can involve stimulating microbes already in the environment or adding nutrients. Bioaugmentation accelerates processes by adding known active microorganisms. The document outlines several biodegradation processes and gives examples of bioremediation and bioaugmentation.
•Introduction of bioremediation: Bioremediation refers to the process of using microorganisms to remove the environmental pollutants i.e. toxic wastes found in soil, water, air etc.
•In situ bioremediation:
It involves a direct approach for the microbial
degradation of xenobiotics at the sites of pollution
(soil, ground water).
•Types of in situ bioremediation:
Natural attenuation.
Engineered in situ bioremediation.
- Bioventing, biosparging, bioslurping,
phytoremediation.
•Ex situ bioremediation:
Waste or toxic pollutants can be collected from the polluted sites and bioremediation can be carried out at a designated place or site.

HYDROGEN GENERATION FROM WASTE WATER BY USING SOLAR ENERGY | J4RV3I11004Journal For Research
Objective of this paper is to produce hydrogen which is an ideal fuel for the next generation because it is abundantly available in nature, energy efficient and clean. Wide varieties of technologies are available to produce hydrogen but only few of them are considered environmental friendly. Solar water splitting via photo catalytic reaction is one of them which have attracted tremendous attention. In this paper we are working on hydrogen production via solar splitting. Photo catalytic water splitting is one of the promising technologies to produce pure and clean hydrogen. Since it is reasonable having low process cost and has a small reactor, it can be made for house hold application and hence has a huge market potential. Generation of hydrogen under visible irradiation is the main area of work. Based on the literature reported here, visible irradiation can be achieved by doping of TiO2 with metal or non-metal. We have used Fe doping to increase the efficiency. The result indicates that Fe doped sieves produce more hydrogen than the normal TiO2 coated sieve and the efficiency can be increased if we increase the number of doped sieves and surface area.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

6. Introduction
• The Metabolic activities of microbes can also be
exploit in complex natural environments for
beneficial outcomes. Examples are
1. The use of microbial communities to carry out
biodegradation, bioremediation, and environmental
maintenance processes.
2. The addition of microorganisms to soils or plants for
the improvement of crop production.

7. Biodegradation
• Has at least three outcomes:-
1. A minor change in an organic molecule, leaving the
main structure still intact.
2. Fragmentation of a complex organic molecule in such
a way that the fragments could be yield the original
structure.
3. Complete mineralization, which is the transformation
of organic molecules to inorganic forms.
7/21/2018 7
Fst-202 General Microbiology
(Session Fall 2017-21)
8. Biodegradation
• Definition :-
• “ ‘Biodegradation’ is the breakdown of organic
matter by microorganisms.”
• The removal of toxic industrial products in soil and
aquatic environments is a daunting and necessary task.
• Compounds Such as perchloroethylene (PCE),
Trichloroethylene (TCE), and Polychlorinated biphenyls
(PCBs) are common contaminants.
7/21/2018 8
Fst-202 General Microbiology
(Session Fall 2017-21)
9. Biodegradation Processes
• Degradation of complex compounds requires several
discrete stages, usually performed by different
microbes.
• Initially contaminants are converted to less toxic
compounds that are more readily degraded.
• The 1st step for many contaminants, including
organochloride pesticides, alkyl solvent, and aryl
halides, is “reductive dehalogenation”.
7/21/2018 9
Fst-202 General Microbiology
(Session Fall 2017-21)
10. Biodegradation Processes
• This is the removal of a halogen substituent ( e.g.
chlorine, bromine, fluorine) while at the same time adding
electrons to the molecule.
• This can occur in two ways:-
1. In hydrogenolysis, the halogen substituent is replaced by
a hydrogen atom
2. Alternative, dihaloelimination removes two halogen
substituents from adjacent carbons while interesting an
additional bond between the carbons
7/21/2018 10
Fst-202 General Microbiology
(Session Fall 2017-21)
11. Biodegradation Processes
• The dehalogenation of PCBs uses electrons derived
from water
• Alternatively hydrogen can be the electron donor for
the dehalogenation of different chlorinated
compounds.
• Major genera with species that carry out this process
include Desulfitobacterium, Dehalospirillum, and
Desulfomonil.
7/21/2018 11
Fst-202 General Microbiology
(Session Fall 2017-21)
12. Biodegradation Processes
• Another important factor that influences
biodegradation is a compound’s chirality or hardness.
• Microorganisms often degrade one isomer of
substance but not to the other, which will remain in
the environment.
• At least 25% of herbicides are chiral.
• Thus, it is critical to add the herbicides effective and
also degradable.
7/21/2018 12
Fst-202 General Microbiology
(Session Fall 2017-21)
13. Biodegradation Processes
• Degradation processes that occur in soils also can be
used in large-scale degradation of hydrocarbons or
wastes from agricultural operations.
• The waste material is incorporated into the soil or
allowed to flow across the soil surface, where
degradation occurs.
• While this is often very effective, sometimes such
degradation processes doses not reduce toxicity.
7/21/2018 13
Fst-202 General Microbiology
(Session Fall 2017-21)
14. Biodegradation Processes
• An important example of this problem is the
degradation of trichloroethylene (TCE), a widely used
solvent.
• When degraded under anoxic conditions, the
dangerous carcinogen vinyl chloride can be formed.
7/21/2018 14
Fst-202 General Microbiology
(Session Fall 2017-21)
15. Bioremediation
• Definition:-
• “ The use of microbes to transform these
contaminants to non-toxic degradation products is
called ‘Bioremediation ’ ”.
• Bioremediation usually involves stimulating the
degradative activities of microorganisms already
present in contaminated water or soils.
7/21/2018 15
Fst-202 General Microbiology
(Session Fall 2017-21)
16. Bioremediation
• These existing microbial communities cannot carry
out biodegradation processes at a desired rate due to
limiting physical or nutritional factors.
• For example, biodegradation may be limited by low
levels of oxygen, nitrogen, phosphorus, or other
nutrients.
• In these case, it is very necessary to determine the
limiting factors and supply the needed materials or
modify the environment.
7/21/2018 16
Fst-202 General Microbiology
(Session Fall 2017-21)
17. Bioremediation
• Often the addition of easily metabolized organic
matter such as glucose increases biodegradation of
recalcitrant compounds that otherwise would not be
use as carbon and energy sources by microorganisms.
• This process is called “Cometabolism”.
7/21/2018 17
Fst-202 General Microbiology
(Session Fall 2017-21)
18. Bioaugmentation
• Definitions:-
• The acceleration of microbiological processes by the
addition of known active microorganisms to soil, waters,
or other complex systems is called “Bioaugmentation”.
• This is not a new concept; commercial culture
preparations have long been available to facilitate
silage formation and to improve septic tank
performance.
7/21/2018 18
Fst-202 General Microbiology
(Session Fall 2017-21)
19. Bioaugmentation
• However, the magnitude of contamination coupled
with an increased awareness of some of the dangers
cleanup can introduce has stimulate the growth of the
bioremediation industry.
• For instance, an oil dispersant consisting of several
non-pathogenic Bacillus species, wetting agent, and
nutrients is now commercially available.
