TL;DR: Ethanol-enriched anaerobic culture was much better for the reductive biotransformation of 2,4-DNT than methanol- and acetate-en enriched cultures when hydrogen was used as the primary substrate. (via Semantic Scholar)

1997 article

Kinetics of anaerobic cometabolism of 2,4-dinitrotoluene with ethanol as the primary substrate

WATER SCIENCE AND TECHNOLOGY, Vol. 36, pp. 271–278.

By: J. Cheng, M. Suidan & A. Venosa

author keywords: anaerobic; biotransformation; cometabolism; 2,4-dinitrotoluene; ethanol; inhibition; kinetics; model
TL;DR: A kinetic model that describes the anaerobic cometabolism of 2,4-dinitrtoluene (DNT) with ethanol as the primary substrate has been developed based on experimental results and exhibits a very strong competitive inhibition to further biotransformation of 4-A-2-NT and 2,A-4-NT.

1996 journal article

Anaerobic biotransformation of 2,4-dinitrotoluene with ethanol as primary substrate: Mutual effect of the substrates on their biotransformation

WATER RESEARCH, 30(2), 307–314.

By: J. Cheng*, Y. Kanjo*, M. Suidan* & A. Venosa*

author keywords: 2,4-dinitrotoluene; anaerobic biotransformation; ethanol; primary substrate; methanogenic culture; biochemical methane potential; propionate; inhibition
TL;DR: 2,4-DNT inhibited its own biotransformation as well as the acetogenesis of ethanol and caused a decrease in the extent of formation of propionate with acetate production being favored. (via Semantic Scholar)
