Question

Which of the following is not a biofilm?

(a) Dental plaque

(b) Slimes

(c) Biofouling

(d) Biogenic Amines

This question was addressed to me in an interview for internship.

This interesting question is from Microbiology in section Yeast Management & Microbiology of Fermentation Technology

Answer 1

Right choice is (d) Biogenic Amines

For explanation I would say: Biogenic Amines are not a biofilm. Dental plaque, Slimes in water pipes and drains, and biofouling in cooling towers and heat exchangers are the classical biofilms. The biofilms are almost everywhere.
