uses of bacteria

These are bacteria which are able to synthesize their own organic food from inorganic substances. They use carbon dioxide for obtaining carbon and utilise hydrogen sulphide (H 2 S) or ammonia (NH 3 ) or hydrogen (H 2 ) as the source of hydrogen to reduce carbon. These bacte..

One of the unsolved mysteries in biology is that of viruses. Due to the absence of a cellular organization viruses cannot be placed with either prokaryotes or eukaryotes. They are considered as intermediate between living and non-living systems. Viruses are active and show reproduction only inside ..
