Question

3. Retaining food quality for longer time
4. Rhizobium, Clostridium and Azotobactor
5. The process of conversion of sugar into alcohol by yeast​

Answer 1

Answer:

1.

To retain quality and nutritive value, stock only the kinds and amounts of food you can store properly. Proper storage means maintaining a clean refrigerator and freezer. Avoid overcrowding the refrigerator. Arrange items so cold air can circulate freely.

2.

Rhizobium, Azotobacter, Beijerinckia, and Clostridium are some example of nitrogen-fixing bacteria. Nitrosomonas is a nitrifying bacteria which assists in the process of nitrification. Nitrification is the oxidation or conversion of ammonia to nitrite to nitrate.

3.

Fermentation is a metabolic process that converts sugar to acids, gases or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation.
