Solution
The correct options are A Spirulina - Single cell protein BRhizobium - Biofertilizer CStreptomyces - Antibiotic
Rhizobium present in root nodules of leguminous plants fixes nitrogen gas (N) from the atmosphere turning it into a more readily useful form of nitrogen (N).
The most interesting property of Streptomyces is the ability to produce bioactive secondary metabolites, such as antifungals, antivirals, antitumor and, anti-hypertensives, immunosuppressants, and especially antibiotics.
Serratia is known to cause nosocomial infections.
Spirulina has a high supply of carotenoids such as beta-carotene and yellow xanthophylls and is used as single cell protein. So the correct options are A, B and C.
