LIFE SCIENCE

Detailed explanation-1: -This produces natural gas which is used as a fuel. Why are bacteria useful in this example of biotechnology? Bacteria are involved in the nitrogen cycle. Bacteria can reproduce very quickly.

Detailed explanation-2: -We use bacteria as protein factories Bacteria can translate foreign genes into proteins – and scientists have ways to ensure that the bacteria make the proteins in large amounts. For these reasons, bacteria can function as ‘protein factories’, producing medically important proteins and others.

Detailed explanation-3: -Bacteria are extremely useful for genetic engineering purposes because: They contain the same genetic code as the organisms we are taking the genes from, meaning they can easily ‘read’ it and produce the same proteins.

Detailed explanation-4: -Numerous species of bacteria have evolved which can oxidize petroleum and its products for their sole source of carbon and energy, similarly bacteria have played a crucial role in the process of petroleum formation by catalyzing many biological and reactions in the marine sediments rich in organic matter .

Detailed explanation-5: -These bacteria are known as hydrocarbon degrading bacteria. Pseudomonas can digest the hydrocarbons in oil. They are gram negative bacteria that are found in soil, water and plants and animals. A species called Pseudomonas putida is widely used in oil spill decontamination or bioremediation.
