 (a) Single cell proteins can be used as an alternate source of proteins for human nutrition. Illustrate with two examples.
(b) How can tissue culture be applied to recover healthy plants from virus-infected plants?

Text Solution

Verified by Experts

(a) (1) Microbes like spirulina can be grown easily on materials like waste water from potato processing plants, straw, molasses etc. to produce large quantities of food rich in proteins.
(ii) 250 g of microorganism, Methylophilus methylotrophus can produce about 200 g of protein per day.
Thus SCP can be used as an alternate source of proteins for human nutrition.
(b) Although the plant is infested with a virus, the meristem is free of virus. Hence, the meristem can be grown in vitro conditions to obtain virus free plants.

What are single cell protein? Mention their significance. b) Name any two organisms that are used as single cell protein.

The boiling point elevation and freezing point depression of solutions have a number of partical applications. Ethylene glycol (CH_(2)OH-CH_(2)OH) is used in automobile radiatiors as an antifreeze because it lowers the freezing point of the coolant. The same substance also helps to prevent the radiator coolant from boiling away by elevating the boiling point. Ethylene glycol has low vapour pressure. We can also use glycerol as an antifreeze. In order for the boiling point elevation to occur, the solute must be non-volatile, but no such restriction applies to freezing point depression. For example, methanol (CH_(3)OH) , a fairly volatile liquid that boils only at 65^(@)C , is sometimes used as an antifreeze in automobile radiators. 124 g each of the two reagents glycol and glycerol are added in 5 kg of water of the radiators in two cars.
