Microbial Degradation of the Sulfonate of Dodecyl Benzene Sulfonate [PDF]
Applied Microbiology, 1965 It has been observed that the sulfonate portion of alkyl benzene sulfonate (ABS) will undergo microbial attack in certain pure and mixed cultures if an energy source, such as glucose, is available. The evidence for this is provided by the stoichiometric relationship between the reduction of ABS concentration and the appearance of inorganic sulfur ...
