APPLICATIONS OF MICRO- ORGANISMS IN
INDUSRIES
Producing biogas
• A mixture containing organic
materials such as straw, cow dung
and water is used to produce
biogas.
• Anaerobic bacteria such as
Methanococcus react on these
organic surfaces and produce
biogas.
• Biogas mainly consists of Methane
gas. Therefore, it can be used as an
energy source.
Metal extraction
• The most simple and effective
technology used for the metal
extraction from low grade ores, by
the use of microbes, is known as
bio-leaching.
• Uranium and Copper are such two
metals that are extracted by bioleaching.
