Question
Chapter 15.9, Problem 1CR
Summary Introduction
The sulfate reducing bacteria (SRB) are obligate anaerobes therefore, strict anaerobic condition must be maintained during their cultivation or growth. The sulfate reducers show a wide range of morphological and biochemical diversity. Sulfate is highly deposited in the seawater, sediments and water having high concentrations of decaying organic materials therefore, large population of sulfate reducers can be seen in such environments. For this reason, these bacteria have been employed for cleaning the contaminants.
