  • Bioremediation of pollutant-contaminated water

    Raw water resources in Kafr El-Sheikh Governorate are affected by many contaminants particularly during the winter season and low demand period of the Nile River, in which water level decreases and organic matter increases resulting in decreased dissolved oxygen, and increased ammonia, nitrite and bacterial load in the water. In this study, physicochemical and microbiological characteristics ...

  • Dual bioremediation of phenol and Cr(VI) by mixed microbial cultures in the presence of molasses

    Simultaneous phenol and Cr(VI) bioremoval by two different mixed cultures, from petroleum-contaminated soil (PS) and boron-contaminated wastewater (BW), was investigated in regard to different culture media, pH levels (6–8), initial phenol (25–100 mg/L) and Cr(VI) (15–50 mg/L) concentrations. The optimum medium was found to be mineral salt medium tested, which contained 1% (v/v) molasses ...

  • Nanobite bioremediates a Contaminated harbour - Case study

    When a hydrocarbon is spilled on water, it is very visible – floating on the surface, a blue green sheen clearly visible. When applied to an oil spill on water, Nanobite Liquid will not mix with the water and become diluted. Within a minute it attaches to the hydrocarbon, bonding with it and creating a matrix – an agglomerated gel- that remains on the surface and cannot sink, no ...

  • Feasibility study of in-situ bioremediation for nitrobenzene-contaminated groundwater

    Although many studies have simulated in-situ bioremediation of contaminated groundwater, most of them have not considered hydrochemical conditions and indigenous microorganisms, thus potentially rendering results inapplicable to actual in-situ groundwater bioremediation projects. This study focused on a nitrobenzene-contaminated groundwater site located in Jilin City, China. The actual ...

  • Sulfate-Enhanced bioremediation of BTEX - Case Study

    Problem A former gas station in North Carolina contaminated groundwater with BTEX from a UST basin. The site is now in the median of a busy four-lane highway. Residents within 250 feet of the site use an irrigation well, prompting the need to conduct proactive remedial action. Site conditions of sand and clay above partially weathered bedrock and depleted sulfate concentrations within the ...

  • Rapid decolorization of methyl orange by a novel Aeromonas sp. strain DH-6

    Azo dyes are extensively used, but are recalcitrant and refractory. In this study, an indigenous strain DH-6 was isolated and identified as Aeromonas sp. based on 16S rDNA analysis for its excellent methyl orange (MO) decolorizing capability. Plackett–Burman design and response surface methodology (RSM) were employed to investigate the effect of operational parameters on ...

  • Operating conditions for the continuous bioremediation of free cyanide contaminated wastewater using Aspergillus awamori

    Generation of cyanide-containing wastewater is a growing problem worldwide as numerous cyanide complexes are highly unstable and degrade to form free cyanide (F-CN), the most toxic form of cyanide. Agro-waste materials, such as sweet orange (Citrus sinensis) waste from the citrus industry, are rich in readily metabolisable carbohydrates that can supplement microbial activity and thus support ...

  • Biodegradation of fenpropathrin by a novel Rhodopseudomonas sp. strain PSB07-8

    The aim of our study was to isolate a fenpropathrin-degrading bacterial strain and to determine its effectiveness in bioremediating fenpropathrin-contaminated soil in the laboratory. We isolated a bacterial strain from soils and named it as PSB07-8, and showed that this organism was able to degrade pyrethroid pesticide fenpropathrin. The organism was identified as a strain of Rhodopseudomonas ...

  • Outstanding bioremediation in winter months case study

    Alga Power 101 was again able to prove its efficacy when it was utilized on a former industrial site in West Thurrock, Essex, under some extremely challenging conditions. Formerly a scrapyard, the contaminated site was heavily laden with diesel and other fuels. Prior to treatment the TPH of the soil ranged between 8,000mg/kg and 10,000mg/kg. Bioremediation took place between November and December ...

  • CL-Out In Situ Bioremediation of Perchlorate

    CL-Out is a consortium of facultative aerobic organisms that are well know for their ability to utilize nitrates.  CL-Out is generally used for the aerobic cometabolism of PCE and other chlorinated solvents.  As the half-reaction for perchlorate is close to that of nitrate, CL-Out cometabolism of perchlorate was successfully tested in the laboratory.  In addition to laboratory ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...
