The effectiveness of hydrocarbon bioremediation strategies approaches is depending on various issues such as type and volume of pollution, nutrient accessibility in the target ecosystem, time, biodiversity of microorganisms, pollutant bioavailability and many others. In the present research, laboratory studies were carried out on the bioremediation of coastal sediment samples ...

Dehalococcoides mccartyi strain WBC-2 dechlorinates carcinogen vinyl chloride to ethene in the West Branch Canal Creek (WBC-2) microbial consortium used for bioaugmentation. We assembled and closed the complete genome sequence of this prokaryote using metagenomic sequencing from an enrichment culture.

Autoclaving of crude oil is often used to evaluate the hydrocarbon-degrading abilities of bacteria. This may be potentially useful for bioaugmentation and microbial enhanced oil recovery (MEOR). However, it is not entirely clear if "endogenous" bacteria (e.g., spores) in/on crude oil survive the autoclaving process, or influence subsequent evaluation of the hydrocarbon-degradation abilities of ...

The use of plants to remove Poly-aromatic-hydrocarbons (PAHs) from soil (phytoremediation) is emerging as a cost-effective method. Phytoremediation of contaminated soils can be promoted by the use of adding microorganisms with the potential of pollution biodegradation (bioaugmentation). In the present work, the effect of bacterial consortium was studied on the capability of Sorghum and Onobrych...

Biogas production technologies commonly involve the use of natural anaerobic consortia of microbes. The objective of this study was to elucidate the importance of hydrogen in this complex microbial food chain. Novel laboratory biogas reactor prototypes were designed and constructed. The fates of pure hydrogen-producing cultures of Caldicellulosiruptor saccharolyticus and Enterobacter cloacae we...

The debate over the efficacy of bioaugmentation rages on, with research continuing to demonstrate that its advantages for soil bioremediation are difficult to predict; however, when it works, the results are often very encouraging. The difficulties arise from, among others, the diversity of the microorganisms used, environmental heterogeneity, and variations in the influence of critical paramet...

Bioremediation is a low-cost, clean, and environmentally friendly method in managing marine pollution. Despite its great potential, bioremediation has own challenges. As an open system, limited nutrients fluctuating environmental conditions the ocean affect metabolism of degrading microorganisms, thus influencing biodegradation rate. Multiple strategies have been employed to enhance rate at var...

Seed endophyte inoculation can enhance the plant tolerance to pollutants, which allows cultivation on trace element (TE) polluted soils. Methylobacterium sp. CP3 and Kineococcus endophyticus CP19 were tested in vitro for their Zn Cd growth promotion traits. The vivo effects of bioaugmentation with individual strains or both using two poplar cultivars, Populus deltoides x (P. trichocarpa P. maxi...

Bioaugmentation – the addition of specific microorganisms to microbial consortia obtain functions - is a promising method improve performance sub-optimal anaerobic digestion processes and recover methane production. The present study implements for first time model with bioaugmentation functionalities, enabling dynamic microbiological augmented systems. based on previous advanced mathematical f...
