Solution
The correct option is C High rate of biomass production
Single Cell Protein is an edible protein extracted from pure microbial cultures, dead, or dried cell biomass. It acts as an alternative protein source to humans and animals.
Microbes like algae (Chlorella), fungi (Candida), yeast (Saccharomyces), and bacteria (Methylophilus methylotrophus) are used as SCP.
These microbes multiply rapidly and can be easily grown using inexpensive substrates. These substrates include agricultural wastes, wood shavings, waste water from the potato processing industry, human and animal wastes, etc. Using wastes generated from different sectors in the production of SCP make it cost effective.
The ability to grow on inexpensive substrate is not the reason behind the high yield from SCP production. This makes SCP culture a good method for pollution reduction. Hence option b is incorrect.
The microbes used in SCP provide high yield of protein in short generation time due to their high multiplication rates (fast growth). Within a short time large number of microbial cells are produced which results in high rate of biomass (total amount of living matter) production. Hence option c is correct and option a is incorrect.
For example, Methylophilus methylotrophus is a bacteria which is rich in protein. 250 kg of cow produces only 200 g of protein per day and in the same period 250 g of bacteria can produce 25 tonnes of protein.
