The bacteria from Antarctica are components of an anaerobic microbial consortium that is used for seeding (inoculation) of bio-digesters. The consortium is composed of bacteria belonging to four groups, which work in a sequential manner. The Antarctic bacteria which are cold active (work in wide temperature range) constitute the first two groups, i.e. hydrolytic & acidogenic. Cow dung, being abundantly available at low cost, has been used for multiplication of bacteria used in the bio-digester.
The cow dung is used only during multiplication of bacteria in the inoculums generation facility, which is a closed system. Once it is consumed by the bacteria and converted into a form that does not have any fly attractant property and rather detracts them. Final bacteria fed into the bio-digester do not have any unpleasant odor and get washed away in the bio-digester within few days. At present, no additional measures are required to prevent them.
