Diversity of methane and short chain hydrocarbon degrading bacteria with an emphasis on methane biofilter systems
Methanotrophs house enzymes capable of methane oxidation, act as a sink for atmospheric methane and play a key role in the global carbon cycle. This study conducted multiple studies on methanotrophs, including: examination of the evolutionary history of copper membrane monooxygenases (CuMMOs), …

Marine microbial communities capable of hydrocarbon biodegradation along shipping routes in the Kivalliq region of the Canadian Arctic
… and cultural livelihood. Naturally occurring hydrocarbon-degrading bacteria within the marine microbiome have the potential to catalyze biodegradation of crude oil compounds, with previous studies showing cold-adapted oil-degrading bacteria inhabiting different marine biomes in the Canadian …

2-D and 3-D tools for electrical imaging in environmental applications
… measures of presence and degradation activity of hydrocarbon-degrading biomass.

An Evaluation of the Effects of Marine Oil-spills, Remediation Strategies, and Shipwrecks on Microbial Community Structure and Succession
… significantly increased growth of obligate hydrocarbonoclastic bacteria (OHCB) in 24 hours, translating into significantly enhanced alkane-biodegradation. Early sampling of microcosms revealed how the OHCB Oleispira, hitherto considered a psychrophile, can dominate bacterial communities at …

The effect of freeze /thaw temperature fluctuations on microbial metabolism of petroleum hydrocarbon contaminated Antarctic soil
… a statistically significant loss of petroleum hydrocarbons occurred at stable temperature. Approximately 440 mg/Kg of the starting average petroleum hydrocarbon concentration (38%) were lost by the 56th day of the experiment. Approximately 163 mg/Kg of was lost from the volatilization control …

Functional characterisation of alkane-degrading monooxygenases in Rhodococcus jostii strain 8
Short-chain alkanes are gaseous hydrocarbons that contribute to photochemical pollution and ozone production in the atmosphere. A number of studies have shown that Rhodococcus species possess the ability to metabolite a wide range of hydrocarbons since they contain multiple hydrocarbon-degrading …

Biodegradation, water solubility and characterisation studies of unresolved complex mixtures (UCMs) of aromatic hydrocarbons
… processes which remove the simple, volatile hydrocarbons leaving an unresolved complex mixture (UCM) comprising the more environmentally persistent components. Aromatic UCMs have been reported in a wide variety of environmental matrices. Recent studies indicate such material, particularly …

Bioremediation of modelled petroleum-contaminated soils of the Niger Delta and the impact of zeolite augmentation
… of the Niger Delta by a mixed culture of three hydrocarbon-degrading bacteria, Acinetobacter sp, Rhodococcus sp and Pseudomonas sp, was investigated. These bacterial strains were selected based on criteria that they were able to utilize hydrocarbons (hexadecane and sodium benzoate) as the sole …

Characterisation of surfactant-expressing bacteria and their potential bioremediation properties from hydrocarbon-contaminated and uncontaminated soils
… was to characterise the bacteria isolated from hydrocarbon-contaminated soils in the UK and Nigeria that express biodegradation properties. The specific objectives were to isolate and characterise surfactant-producing bacteria from various soils, and to identify lipase-producing bacteria for …

Characterization and comparison of microbial communities from different tourist ports in Mediterranean Sea and evaluation of applicability of bioremediation treatments
… areas. Specifically, pollution by petroleum hydrocarbons is one of the major environmental problems in ports and it is mainly associated with the heavy ship/boat traffic and the related facilities located in these areas. The ship transport in ports is powered by diesel. The present study was …
