Degradation of Endrin, Aldrin, and DDT by Soil Microorganisms
TLDR
Twenty microbial cultures which had been shown to degrade dieldrin were tested to determine their ability to degrade endrin, aldrin, DDT, gamma isomers of benzenehexachloride (gamma-BHC), and Baygon, and none of them was able to degrade Baygon or gamma- BHC.Abstract:
Twenty microbial cultures which had been shown to degrade dieldrin were tested to determine their ability to degrade endrin, aldrin, DDT, gamma isomers of benzenehexachloride (gamma-BHC), and Baygon All isolates were able to degrade DDT and endrin, whereas 13 degraded aldrin However, none of them was able to degrade Baygon or gamma-BHCread more

TL;DR: The effects of parathion on the growth of bacteria, fungi, and algae is shown to be dose dependent, with very low concentrations having no effect at all and higher concentrations drastically arresting the multiplication of the microorganisms.

Pesticide relevance and their microbial degradation: a-state-of-art
TL;DR: In this article, the authors have attempted to discuss the recent challenge of pesticide problem in soil environment and their biodegradation with the help of effective indigenous pesticides degrading microorganisms and highlighted and explored the molecular mechanism for the pesticide degradation in soil with effective indigenous microbial consortium.

Degradation of organochlorine pesticides, particularly endosulfan, by Trichoderma harzianum
Arata Katayama,Fumio Matsumura +1 more
TL;DR: Using a cell-free preparation from Trichoderma harzianum, it is demonstrated that endosulfan metabolism in vitro was stimulated by exogenously added NADPH, and the evidence that the initial metabolic product of endOSulfan was endos sulfuran sulfate is concluded.

Dechlorination of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane by Aerobacter aerogenes. I. Metabolic products.
TL;DR: The metabolic pathway was shown to be: DDT --> DDD -->DDMU -->DDMS --> DDNU --> DDA --> DBP, or DDT ― DDE.

Dechlorination of DDT by Aerobacter aerogenes
TL;DR: In cell-free preparations of Aerobacter aerogenes, the use of selected metabolic inhibitors indicated that reduced Fe(II) cytochrome oxidase was responsible for DDT dechlorination, which may possibly explain the persistence of DDT residues in soils and sediments.

Chlorinated Hydrocarbon Pesticides: Degradation by Microbes
TL;DR: In culture, most of the actinomycetes and filamentous fungi tested degraded PCNB; several actinomersetes dechlorinated DDT to DDD, but no microorganism degraded dieldrin.
