Microorganisms in the mining industry - Microbial Growth

Sulphur-oxidising bacteria also have a role to play in the coal mining industry. Increased environmental awareness in many countries means that it is no longer acceptable to burn off the sulphur content of coal as sulphur dioxide, so an alternative must be found. One possibility is the biodesulphurisation of coal, using sulphur-oxidising bacteria to remove the sulphur before combustion. Whilst ...

Microbial Mining Issues Magazine

Microbes can operate in the toughest conditions on Earth, including among the acids and heavy metals of the mining industry. The first microorganisms appeared on Earth 3.7 billion years ago at a time when there was no free oxygen and the atmosphere was composed of methane, carbon dioxide, ammonia and hydrogen. They have since evolved to inhabit almost all parts of the globe, developing

Role of Microorganisms in Industrial Processes

Microorganisms are used in industry to produce a variety of organic compounds including acids, growth stimulants, and enzymes. In some cases the production results from an apparent accident in nature where an organism manufactures many thou­sands of times the amount necessary for its own metabolism. One of the first organic acids to be made in bulk by microorganisms was citric acid.
