❣Antibiotics are medicines PRODUCED by certain micro-organisms to kill other disease-causing micro-organisms.

Precautions to be TAKEN while using antibiotics are:

• i. Antibiotics should be taken under the supervision of a well qualified doctor.

• ii. Course (INTAKE) of antibiotics should be COMPLETED as prescribed by the doctor.

• iii. Antibiotics should be taken in the right amount and at the right time. A wrong DOSE of antibiotics makes the drug ineffective. Also, excessive consumption of drugs may kill the useful bacteria present in our body.

Answer:

Micro-organisms are too small to be seen through naked eyes. However, they are vital to plants and the environment. GIVEN below are the few uses of microorganisms:

LACTOBACILLUS is used to form curd from milk.

Rhizobium present in the roots of pulse plants fix nitrogen from the air and supply nitrogen compounds to the pulse plants.

Micro-organisms are also used in winemaking, baking, pickling, and other food-making processes.

Alcoholic fermentation by yeast is widely used in the preparation of wine and bread.

Microbes are used to reduce pollution. For example, decomposers such as bacteria and fungi break down dead bodies and excreta to form inorganic compounds, which can be absorbed by plants.

Microbes also play an IMPORTANT role in the preparation of medicines. Antibiotics are chemicals produced by micro-organisms to kill bacteria. Penicillin is an antibiotic made from Penicillium.

Bacteria present in our intestine helps in proper digestion and release Vitamin B which is absorbed by the intestine.

Many vaccines are prepared from micro-organisms. These vaccines are given to children to protect them from disease.

Certain microbes are also used in the biological treatment of sewage and industrial effluents.

Yeast is used in making idli, BHATURAS, bread, pastries, and cakes.
