Microbial Biodegradation of Paraffin Wax in Malaysian Crude Oil Mediated by Degradative Enzymes

Frontiers in Microbiology, 2020
The deposition of paraffin wax in crude oil is a problem faced by the oil and gas industry during extraction, transportation, and refining of crude oil. Most of the commercialized chemical additives to prevent wax are expensive and toxic.

Exploring novel alkane-degradation pathways in uncultured bacteria from the North Atlantic Ocean

mSystems, 2023
Microbes play a significant role in the degradation of petroleum hydrocarbons in the oceans, yet little is known about the native bacteria that metabolize hydrocarbons before an oil spill.

Transcriptomic analyses reveal increased expression of dioxygenases, monooxygenases, and other metabolizing enzymes involved in anthracene degradation in the marine alga Ulva lactuca

Frontiers in Plant Science, 2022
To analyze the mechanisms involved in anthracene (ANT) degradation in the marine alga Ulva lactuca, total RNA was obtained from the alga cultivated without ANT and with 5 μM of ANT for 24 h, and transcriptomic analyses were performed.

Interaction of Ammonia Monooxygenase from Nitrosomonas europaea with Alkanes, Alkenes, and Alkynes [PDF]

Applied and Environmental Microbiology, 1988
Ammonia monooxygenase of Nitrosomonas europaea catalyzes the oxidation of alkanes (up to C 8 ) to alcohols and alkenes (up to C 5 ) to epoxides and alcohols in the presence of ammonium ions.

Transcriptomic analysis of Rhodococcus opacus R7 grown on polyethylene by RNA-seq

Scientific Reports, 2021
Plastic waste management has become a global issue. Polyethylene (PE) is the most abundant synthetic plastic worldwide, and one of the most resistant to biodegradation. Indeed, few bacteria can degrade polyethylene.

Assessment of the number of catabolic genes of oil-contaminated soils

Учёные записки Казанского университета: Серия Естественные науки, 2019
In this work, laboratory modeling of three levels of oil contamination (60, 120 and 250 g kg–1) was carried out for three types of soil: eutric podzoluvisols, haplic greyzem, and haplic chernozems.

Primary structure of xylene monooxygenase: similarities to and differences from the alkane hydroxylation system [PDF]

Journal of Bacteriology, 1991
Xylene monooxygenase, encoded by the TOL plasmid of Pseudomonas putida, catalyzes the oxidation of toluene and xylenes and consists of two different subunits encoded by xylA and xylM. In this study, the complete nucleotide sequences of these genes were determined and the amino acid sequences of the xylA and xylM products were deduced. The XylM sequence

Two Distinct Monooxygenases for Alkane Oxidation in Nocardioides sp. Strain CF8 [PDF]

Applied and Environmental Microbiology, 2001
ABSTRACT Alkane monooxygenases in Nocardioides sp. strain CF8 were examined at the physiological and genetic levels. Strain CF8 can utilize alkanes ranging in chain length from C 2 to C 16 .
