Answer 2

The correct match is (d) Serratia - Drug addiction.

• Antibiotic is an antibacterial agent which is used in bacterial infection treatment. Streptomyces is a Gram-positive bacteria that produces many antibiotics such as streptomycin, neomycin etc.
• Serratia induces infections in the urinary tract, wound infections, and pneumonia. This tends to cause endocarditis.
• Rhizobium is a symbiotic bacteria which fixes nitrogen. In conjunction with the legume plants it removes atmospheric nitrogen.
• Consequently it serves as a biofertilizer. Edible unicellular species are single cell protein (SCP). Spirulina is the source of protein in single cells.
