Answer 1

Answer: (B)

(A)- (III), (B)- (IV), (C)- (I), (D)- (II)

Corynebacterium glutamicum is a gram-positive soil bacterium. Through its metabolism, it synthesizes products such as serine, glutamate, and lysine - amino acids.

Many Halobacterium species possess proteinaceous organelles called gas vacuoles or gas vesicles.

Cristispira belongs to spirochete phylum of bacteria. They have a crest-like structure called crista. Their cells are flexible.

Bacillus mycoides is an ammonifying bacteria and can convert peptone (organic Nitrogen source into Ammonia). Thus, the correct answer is (B).
