Chemical substance from which plastic bottles are made.

True or False : Whey is separated from yoghurt.

True or False : Various products like food and cosmetics are produced on a large scale with the help of micro - organisms.

True or False : Useful microbes become inactive due to antibiotics, probiotics make them active again.

True or False : Soyabean sauce is produced with the help of fungus Aspergillus oryzae

In cities sewage needs to be carried to processing unit and acted upon by microbial process. Microbes which can decompose аnу сорpound as well as destroy the pathogens of cholera typhoid are mixed with sewage. They release methane and carbondioxide by decomposition of the carbon compounds present in sewage Phenol oxidising bacteria decompose the xenobiotic chemicals present in sewage.
