What are beneficial microorganisms and its uses in biotechnology?

There are 10% of beneficial microorganisms and 10% of bad microoganisms exist in the world, the rest 80% will be neutral. If either side of microorganisms dominant than the other, then the result will be one sided. The founder of Beneficial Microoganisms Dr Teruo Higa, from Japan has vast research on beneficial microorganisms. He discovered many types of microbes, that benefit many industries such as agriculture, livestock, aquaculture, environment and household. Different microbes perform different work for industries. Recent pharmaceutical company used E coli, a single cell microbe to produce vaccines for many purposes. The technique of cultivation of microbes in big scale by bioreator is commonly practice by many countries. The products produced were used in pharmaceutical industries.


What is the purpose of flaming the loop after use?

I'm assuming you mean an "innoculating loop" in microbiology. You flame the loop to kill the microoganisms on the loop before using it again to prevent mixing different bacterial colonies and contaminating them.
