Question

Which of the following are usually not degraded by aerobic degradation of nitro-aromatics?

(a) Di-nitro derivatives

(b) Mono derivatives

(c) Poly-nitro derivatives

(d) Amino aromatics

The question was posed to me in an interview for internship.

The doubt is from Microbial Transformations of Pesticides topic in portion Microbial Transformations of Pesticides of Environmental Biotechnology

Answer 1

The correct answer is (d) Amino aromatics

Best explanation: Amino aromatics are usually degraded by anaerobic degradation of nitro-aromatics and not by aerobic degradation of nitro-aromatics. Whereas, Di-nitro derivatives, Mono derivatives, Poly-nitro derivatives are degraded by aerobic degradation of nitro-aromatics by microbes.
