materials and methods phe degrading bacteria were isolated from surface sediments. isolated strains were then identified by biochemical and molecular (16s rdna gene sequence) analysis. rsm was employed to evaluate the optimum biodegradation of phe by the most effective isolated strain. the investigated parameters included the temperature, inoculum sizes, ph, nh4cl concentration, and salinity. o...

Polycyclic aromatic hydrocarbons (PAH) are regarded as environmental pollutants. A promising approach to reduce PAH pollution is based on the implementation of the natural potential of some microorganisms to utilize hydrocarbons. In this study Proteiniphilum acetatigenes was used for bioaugmentation of sewage sludge to improve the PAH removal. Bioaugmentation experiments were performed in paral...

With approximately 250 000 marine species, the ocean is a vast reservoir of biodiversity and an abundant biological resource natural polymers microorganisms producing biopolymer-degrading enzymes.

Polycyclic aromatic hydrocarbon (PAH)-contaminated soils are of concern to the Environmental Protection Agency (EPA) due to their mutagenic and carcinogenic nature. Bioremediation of PAHs is aimed at increasing the overall rate of natural degradation. Microbial bioremediation promotes processes by which microorganisms can take up and/or degrade organic molecules and their metabolites. Microorga...
