Medium-chain alkane biodegradation and its link to some unifying attributes of alkB genes diversity

Science of The Total Environment, 2023
Hydrocarbon footprints in the environment, via biosynthesis, natural seepage, anthropogenic activities and accidents, affect the ecosystem and induce a shift in the healthy biogeochemical equilibrium that drives needed ecological services. In addition, these imbalances cause human diseases and reduce animal and microorganism diversity.

Diversity and Abundance of Oil-Degrading Bacteria and Alkane Hydroxylase (alkB) Genes in the Subtropical Seawater of Xiamen Island

Microbial Ecology, 2010
In this report, the diversity of oil-degrading bacteria and alkB gene was surveyed in the seawater around Xiamen Island. Forty-four isolates unique in 16S rRNA sequence were obtained after enrichment with crude oil. Most of the obtained isolates exhibited growth with diesel oil and crude oil.

Molecular characterization of the alkB gene in the thermophilic Geobacillus sp. strain MH-1

Research in Microbiology, 2009
An extremely thermophilic alkane-degrading bacterium, strain MH-1, was isolated from the deep subterranean petroleum reservoir in Shengli oil field, PR China. Based on its physiological characteristics and analysis of its 16S rRNA gene sequence, strain MH-1 was identified as Geobacillus stearothermophilus.

Isolation of an alkane-degrading Alcanivorax sp. strain 2B5 and cloning of the alkB gene

Bioresource Technology, 2010
A Gram-negative coccus, strain 2B5, was isolated from the sea mud of the crude oil-polluted Donghai area in China and identified as Alcanivorax sp. based on its physiological characteristics and analysis of its 16S rRNA gene sequence. Strain 2B5 was able to degrade C(13)-C(30)n-alkanes and branched alkanes (pristane and phytane) from crude oil as the ...

Expression of an alkane monooxygenase (alkB) gene and methyl tert-butyl ether co-metabolic oxidation in Pseudomonas citronellolis

Biotechnology Letters, 2014
Pseudomonas citronellolis UAM-Ps1 co-metabolically transforms methyl tert-butyl ether (MTBE) to tert-butyl alcohol with n-pentane (2.6 mM), n-octane (1.5 mM) or dicyclopropylketone (DCPK) (4.4 mM), a gratuitous inducer of alkane hydroxylase (AlkB) activity.

A new method for the detection of alkane-monooxygenase homologous genes (alkB) in soils based on PCR-hybridization

Journal of Microbiological Methods, 2006
An improved method was developed that allowed the specific detection of the gene alkB (coding for the rubredoxin dependent alkane monooxygenase) from bacteria without any obvious strain specific discrimination using a combination of PCR and hybridization.

Are alkane hydroxylase genes (alkB) relevant to assess petroleum bioremediation processes in chronically polluted coastal sediments? [PDF]

Applied Microbiology and Biotechnology, 2011
The diversity of alkB-related alkane hydroxylase sequences and the relationship between alkB gene expression and the hydrocarbon contamination level have been investigated in the chronically polluted Etang-de-Berre sediments. For this purpose, these sediments were maintained in microcosms and submitted to a controlled oil input miming an oil spill. New

Detection and transcription of n-alkane biodegradation genes (alkB) in the genome of a hydrocarbon-oxidizing bacterium Geobacillus subterraneus K

Microbiology, 2011
The diversity and localization of alkB genes in the genome of the hydrocarbon-oxidizing bacterium Geobacillus subterraneus K, as well as the transcription of alkB genes, were studied as functions of culture growth phase and the hydrocarbon substrates utilized. Analysis of 96 clones containing inserted alkB genes revealed six alkB homologs in the strain

Diversity of crude oil-degrading bacteria and alkane hydroxylase (alkB) genes from the Qinghai-Tibet Plateau

Environmental Monitoring and Assessment, 2017
The aim of this study was to survey the response of the microbial community to crude oil and the diversity of alkane hydroxylase (alkB) genes in soil samples from the Qinghai-Tibet Plateau (QTP). The enrichment cultures and clone libraries were used. Finally, 53 isolates and 94 alkB sequences were obtained from 10 pristine soil samples after enrichment

Diversity of the alkB Genes of n-Alkane Biodegradation in Thermophilic Hydrocarbon-Oxidizing Bacteria of the Genera Geobacillus, Parageobacillus, and Aeribacillus

Microbiology, 2018
Analysis of complete genomes of thermophilic bacteria of the genus Geobacillus, oxidizing n-alkanes and crude oil revealed the ladA gene and its homologues. In the genomes of some strains, the ladA gene was not detected, although they were capable of growth on n-alkanes.
