Use of chemical criteria in assessing the potential for adverse toxic effects in contaminated sites can under or overestimate the necessary level of site cleanup required. The use of ecotoxicity testing provides a more direct assessment of adverse environmental impact. A multi-trophic level soil ecotoxicity assessment was done on soil contaminated with crude oil distilled into five different fr...

Bacterial biocatalysts play a key role in our transition to a bio-based, post-petroleum economy. However, the discovery of new biocatalysts is currently limited by our ability to analyze genomic information and our capacity of functionally screening for desired activities. Here, we present a simple workflow that combines functional metaproteomics and metagenomics, which facilitates the unmediat...

Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environmentfriendly treatment for oilcontaminated sites. Many reports indicated that, large quantities of organic and inorganic compounds are released into the environments every year as results of human activities causing serious environmental problems. Among those pr...

We report here the draft genome sequence of Acinetobacter sp. Strain V2 isolated from the oil contaminated soil collected from ENGEN, Amanzimtoti, South Africa. Degradation of phenolic compounds such as phenol, toluene, aniline etc. at 400ppm in 24h and oil degrading capability makes this organism an efficient multifunctional bioremediator. Genome sequencing of Acinetobacter spp. V2 was carried...

Role of microbes in bioremediation of oil spills has become inevitable owing to their eco friendly nature. This study focused on the isolation and characterization of bacterial strains with superior oil degrading potential from crude-oil contaminated soil. Three such bacterial strains were selected and subsequently identified by 16S rRNA gene sequence analysis as Corynebacterium aurimucosum, Ac...

The relationship between toxicity and soil contamination must be understood to develop reliable indicators of environmental restoration for bioremediation. Two bacterial rapid bioassays, SOS chromotest and the umu test with and without metabolic activation (S-9 mixture), were used to evaluate the genotoxicity of petroleum hydrocarbon-contaminated soil following bioremediation treatment. The soi...

A short-term ecological study was carried out to comparatively evaluate the phytoremediation potential potential of two leguminous plant species. This aimed at quantifying residual TPH as index for assessing a post-phytoremediated crude oil contaminated soil. Plant and soil analysis were carried out using the photometric method of American Petroleum Institute (API). Result has shown that Leucae...

Mangrove sediment harbors a unique microbiome and is a hospitable environment for a diverse group of bacteria capable of oil biodegradation. Our goal was to understand bacterial community dynamics from mangrove sediments contaminated with heavy-oil and to evaluate patterns potentially associated with oil biodegradation is such environments. We tested the previously proposed hypothesis of a two-...

the effects of arbuscular mycorrhizal fungi on nitrogen concentration of berseem clover were examined in contaminated soil with cadmium. examined factors included: levels of arbuscular mycorrhizal fungi inoculation ( glomus mosseae ) (with and without inoculation), and different levels of soil contamination by cadmium (0, 5, 10, 20, 40 and 80 mg.kg-1). the results showed that the effects of cad...
