Microbial Community Response to Simulated Petroleum Seepage in Caspian Sea Sediments

Frontiers in Microbiology, 2017
Anaerobic microbial hydrocarbon degradation is a major biogeochemical process at marine seeps. Here we studied the response of the microbial community to petroleum seepage simulated for 190 days in a sediment core from the Caspian Sea using a sediment ...

Leaf wax n-alkanes in modern plants and topsoils from eastern Georgia (Caucasus) – implications for reconstructing regional paleovegetation [PDF]

Biogeosciences, 2018
Long-chain n-alkanes originate from leaf waxes of higher terrestrial plants, they are relatively resistant against physical and chemical degradation and are preserved in sediment archives for at least millennial timescales.

Metabolic and stress responses of Acinetobacter oleivorans DR1 during long‐chain alkane degradation

Microbial Biotechnology, 2017
Summary Acinetobacter oleivorans DR1 can utilize C12–C30 alkanes as a sole carbon source but not short‐chain alkanes (C6, C10). Two copies of each alkB‐, almA‐ and ladA‐type alkane hydroxylase (AH) are present in the genome of DR1 cells.

Identification of alkane hydroxylase genes in Rhodococcus sp. strain TMP2 that degrades a branched alkane [PDF]

Biotechnology Letters, 2008
Rhodococcus sp. TMP2 is an alkane-degrading strain that can grow with a branched alkane as a sole carbon source. TMP2 degrades considerable amounts of pristane at 20 degrees C but not at 30 degrees C. In order to gain insights into microbial alkane degradation, we characterized one of the key enzymes for alkane degradation.

Cytochrome P450 Alkane Hydroxylases of the CYP153 Family Are Common in Alkane-Degrading Eubacteria Lacking Integral Membrane Alkane Hydroxylases [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT Several strains that grow on medium-chain-length alkanes and catalyze interesting hydroxylation and epoxidation reactions do not possess integral membrane nonheme iron alkane hydroxylases. Using PCR, we show that most of these strains possess enzymes related to CYP153A1 and CYP153A6, cytochrome P450 enzymes that were ...

Identification of long-chain alkane-degrading (LadA) monooxygenases in Aspergillus flavus via in silico analysis

Frontiers in Microbiology, 2022
Efficient degradation of alkanes in crude oil by the isolated Aspergillus flavus MM1 alluded to the presence of highly active alkane-degrading enzymes in this fungus. A long-chain alkane-degrading, LadA-like enzyme family in A. flavus was identified, and

Characterization and Transcriptional Regulation of n-Alkane Hydroxylase Gene Cluster of Rhodococcus jostii RHA1

Microorganisms, 2019
Gram-positive actinomycete Rhodococcus jostii RHA1 is able to grow on C10 to C19 n-alkanes as a sole source of carbon and energy. To clarify, the n-alkane utilization pathway—a cluster of 5 genes (alkBrubA1A2BalkU) which appeared to be involved in ...

The genome of the moderate halophile Amycolicicoccus subflavus DQS3-9A1(T) reveals four alkane hydroxylation systems and provides some clues on the genetic basis for its adaptation to a petroleum environment. [PDF]

PLoS ONE, 2013
The moderate halophile Amycolicicoccus subflavus DQS3-9A1(T) is the type strain of a novel species in the recently described novel genus Amycolicicoccus, which was isolated from oil mud precipitated from oil produced water.

Ecosystem-scale genomic and metatranscriptomic evidence for a coupled, active short-term hydrocarbon cycle in the marine photic ocean

Applied and Environmental Microbiology
Natural hydrocarbon seeps and human activities are the primary pathways by which oil enters the sea. Marine Cyanobacteria, among the most abundant photosynthetic organisms in the world, continuously produce alkanes, an additional substantial hydrocarbon ...
