They serve a double purpose. Antibiotics are chemical substances produced by certain microbes which functions either by killing or retarding the growth of harmful microbes without affecting the host cells. The first industrially produced microbial enzymes were obtained from the fungal amylase in the year 1896 and were used to cure indigestion and several other digestive disorders. A part of the fixed nitrogen passes into the tissues of legume plant and a part diffuses into the surrounding soil. of using cellulose and lignin and other structural plant compounds; (2) Which types of bacteria are used in Bt-cotton?

The crown gall of beets and hairy root of apple are the examples. The latter sours the milk and coagulates the milk proteins (casein) forming curds and whey. Some photosynthetic bacteria (photoheterotrophs) require redox pairs in the table above to the full reactions in the table below). Biofertilizers add nutrients through natural processes by stimulating the synthesis of enzymes that help the plant absorb the nutrients it requires. process. In consequence a variety of elements of minerals of the earth such as carbon, oxygen, hydrogen, sulphur and phosphorus which make up their bodies are reduced to simple compounds such as carbon monoxide, water, nitrates, sulphates and phosphates. compared to the tissue in the herbivore. They grow in the root hair in the form of a continuous thread-like mass which finally reaches the root cortex. Soils deficient in oxygen are also favourable for the activity of this type of bacteria.
