Abstract The pollution of terrestrial and aquatic environments by petroleum contaminants, especially diesel fuel, is a persistent environmental threat requiring cost-effective environmentally sensitive remediation approaches. Bioremediation one such approach, but dependent on the availability microorganisms with necessary metabolic abilities adaptability. aim this study was to examine microbial...

Following the trend of studies that investigate microbial ecosystems using different metagenomic techniques, we propose a new integrative systems ecology approach that aims to decipher functional roles within a consortium through the integration of genomic and metabolic knowledge at genome scale. For the sake of application, using public genomes of five bacterial strains involved in copper biol...

aroa is an important gene which produces aromatic amino acids essential for bacterial life. the sequence of this gene was shown to be different in bacteria, so the purpose of this study was sequencing of aroa gene in native e. coli o78: k80 to determine the putative differences between this strain and other e. coli o78: k80 strains in gene bank. pcr was used to amplify aroa gene in native e. co...

Globally, the trichothecene mycotoxins deoxynivalenol (DON) and nivalenol (NIV) are among the most widely distributed mycotoxins that contaminate small grain cereals. In this study, a bacterial consortium, PGC-3, with de-epoxydation activity was isolated from soil by an in situ soil enrichment method. Screening of 14 soil samples that were sprayed with DON revealed that 4 samples were able to b...

In the present study we examined the performance of a thermoalkalophilic bacterial consortium, where the predominant strain was Bacillus sp. SF, in the degradation of Reactive Black 5 (RB5). We used a reactor working in continuous mode and investigated the effects of pH, hydraulic retention time (HRT) and several added salts on colour and chemical oxygen demand (COD) reductions. For the chosen ...

The extensive use of petroleum and petroleum products leads to serious oil contamination of the environment, thus considerable interests were taken in microbial degradation and detoxification of these pollutants. Microalgae play an important role in the environmental cleaning of pollutants. Microalgae provide O2 to aerobic bacteria to mineralize pollutants and then take-up the released CO2 [1]....

Effective translation of research findings from laboratory to agricultural fields is essential for the success of biocontrol or growth promotion trials employing beneficial microorganisms. The rhizosphere is to be viewed holistically as a dynamic ecological niche comprising of diverse microorganisms including competitors and noxious antagonists to the bio-inoculant. This study was undertaken to...

Seed inoculation with bacterial consortium was found to increase legume yield, providing a higher growth than the standard nitrogen treatment methods. Alfalfa plants were inoculated by mono- and binary compositions of nitrogen-fixing microorganisms. Their physiological and biochemical properties were estimated. Inoculation by microbial consortium of Sinorhizobium meliloti T17 together with a ne...
