उत्तर
Advantages:
- Spirulina serves as a good source of proteins (SCP).
- These can be produced throughout the year.
- Large quantities of SCP from very small land area can be obtained due to rapid growth of microbes.
- Substrates used may be cheaper or even wastes.
- Some SCPs are good sources of B-complex vitamins.
- So SCP is expected to solve the problem of protein deficiency in the children of developing countries. (But SCP may contain toxic compounds produced by some microbes and may lead to indigestion and allergic reactions.)
