Resting cells of bacteria grown in the presence of diphenylmethane oxidized substituted analogs such as 4-hydroxydiphenylmethane, bis(4-hydroxyphenyl)methane, bis(4-chlorophenyl)methane (DDM), benzhydrol, and 4,4'-dichlorobenzhydrol. Resting cells of bacteria grown with benzhydrol as the sole carbon source oxidized substituted benzhydrols such as 4-chlorobenzhydrol, 4,4'-dichlorobenzhydrol, and other metabolites of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT), such as DDM and bis(4…

TLDR
The results demonstrate that the pathway for DDT degradation in P. chrysosporium is clearly different from the major pathway proposed for microbial or environmental degradation of DDT.
Characterization of new bacterial transformation products of 1,1,1-trichloro-2,2-bis-(4-chlorophenyl) ethane (DDT) by gas chromatography/mass spectrometry.
TLDR
A number of phenolic metabolites were identified as the trimethylsilyl derivatives in the bacterial extracts by gas chromatography/mass spectrometry and a metabolic scheme accounting for their formation is proposed.
Metabolism of DDT [1,1,1-Trichloro-2,2-bis(4-chlorophenyl)ethane] by Alcaligenes denitrificans ITRC-4 Under Aerobic and Anaerobic Conditions
TLDR
An isolated bacterium, Alcaligenes denitrificans ITRC-4, metabolizes 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT) under both aerobic and anaerobic conditions and metabolizes 4-chlorobenzoate, which is accompanied by the release of chloride ions.
Recalcitrance of 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene to degradation by pure cultures of 1,1-diphenylethylene-degrading aerobic bacteria
TLDR
The results of the present study show that, at least for some bacteria, the chlorination of DDE is the main reason for its resistance to biodegradation by styrene and DPE-degrading bacteria.
Aerobic degradation of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT) by Alcaligenes eutrophus A5
TLDR
It is indicated that DDT appears to be oxidized by a dioxygenase in A. eutrophus A5 and that the products of this oxidation are subsequently subjected to ring fission to eventually yield 4-chlorobenzoic acid as a major stable intermediate.
Fenton (H2O2/Fe) reaction involved in Penicillium sp. culture for DDT [1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane)] degradation
TLDR
It is proposed that the degradation of the DDT mixture by Penicillium sp.
A novel metabolic pathway for biodegradation of DDT by the white rot fungi, Phlebia lindtneri and Phlebia brevispora
TLDR
Results indicate that the white rot fungi P. lindtneri and P. brevispora can degrade DBP/DBH through hydroxylation of the aromatic ring, demonstrating that the cleavage reaction of the aliphatic-aryl carbon bond occurs in the biodegradation process of DDT bywhite rot fungi.

TLDR
A meta-fission pathway for the degradation of DDD is proposed based on the recovery of seven chlorinated metabolites identified by gas chromatography-mass spectrometry analysis.

Dechlorination of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane by Aerobacter aerogenes. I. Metabolic products.
TLDR
The metabolic pathway was shown to be: DDT --> DDD -->DDMU -->DDMS --> DDNU --> DDA --> DBP, or DDT ― DDE.
Products Formed from Analogues of 1,1,1-Trichloro-2,2-Bis(p-Chlorophenyl) Ethane (DDT) Metabolites by Pseudomonas putida
TLDR
Cultures of Pseudomonas putida growing in solutions with diphenylmethane as sole carbon source formed 1,1,1',1'-tetraphenyldimethyl ether, and the formation of benzophenone, benzhydrol, and phenylglycolic acid was established and it was revealed that phenylacetic acid was a major metabolite.
Location and consequences of 1,1,1-trichloro-2,2-bis(p-chlorophenyl) ethane uptake by Bacillus megaterium.
TLDR
The atypical macroscopic appearance of membranes isolated from treated cells suggested that cell death may result from altered membrane chemistry, and levels of DDT as low as 1 mug/ml enhanced the rate of death in the population.
Bacterial Methylation of Chlorinated Phenols and Guaiacols: Formation of Veratroles from Guaiacols and High-Molecular-Weight Chlorinated Lignin
TLDR
Two strains of bacteria were shown to metabolize mono-, di-, tri-, and tetrachloroguaiacols and pentachlorophenol to the corresponding O-methyl compounds, and the possible environmental consequences resulting from synthesis of these highly lipophilic substances are discussed briefly.
DDT metabolized by Microorganisms from Lake Michigan
TLDR
A study of the metabolism of DDT by microorganisms isolated from water and bottom silt of Lake Michigan and related water systems and indicates that TDE is the principal product ofDDT metabolism in aquatic environments.
Bacterial degradation of diphenylmethane, a DDT model substrate.
TLDR
A strain of Hydrogenomonas was isolated by elective culture in a solution with diphenylmethane, an analogue of DDT, as the sole carbon source, and phenylacetic acid was found as a major degradation product.

Effect of nutritional factors on DDT-degradation by Mucor alternans.
TLDR
The effects of nutritional factors on the capacity of Mucor alternans to degrade 14C-DDT in shake cultures were investigated, and growth on other sugars resulted in a decrease in the production of DDT-metabolites, which was most noticeable when maltose was used.
