Transgenic bacteria are microbes carrying clones of foreign genes. It is also known as genetically modified bacteria. These bacteria are being employed for many functions .
(a) Two DNA sequence (coding for A and B chains of human insulin) were introduced into the plasmid of bacteria E. Coli. This transgenic bacteria produced insulin chain- Used as biochemical factories
(b) Microbes have been genetically changed to help in cleaning the polluted environment,
eg:- Pseudomonas putida for cleaning oil spills pseudomonas species for removing heavy metal pollutants. Aceto bacter aerogans for decomposition of DDT and Flavobacterium for decomposition of 2,4-D.
