2. INTRODUCTION
• Microbial biomass refers the total amount of
organic matter present in micro-organisms.
• It decomposes plant and animal residues and soil
organic matter.
• It is used in microbial biofuel conversion and
microbial electrochemical systems.
• It can serve as an alternative for the fossil fuel.

4. WHY USE MICROBIAL BIOMASS ???
• Increasing demand of energy throughout the world.
• Less environment pollution.
• Depletion of fossil fuel reserve.
• Rise of biotechnology for green energy.

11. FACTORS
There are several factors that affects the fuel production,
they are :
• pH
• Suitable strain
• Temperature
• Sterile Condition
• Agitation

14. Disadvantages
OUR ROLE???
14
• Advanced pretreatment technology.
• Cost minimization of product recovery.
• Advancement of separation technology.
• High yielding genetically modified organism.

15. CONCLUSION
• Fossil fuel resources show clearly that they are
grossly inadequate to meet global demands in a
sustainable way.
• We can obtain a large amount of energy from
microbial biomass.
• In short, energy obtained from microbial biomass can
serve as an alternative for the fossil fuel.
