  • Robustness of an aerobic metabolically vinyl chloride degrading bacterial enrichment culture

    Degradation of the lower chlorinated ethenes is crucial to the application of natural attenuation or in situ bioremediation on chlorinated ethene contaminated sites. Recently, within mixtures of several chloroethenes as they can occur in contaminated groundwater inhibiting effects on aerobic chloroethene degradation have been shown. The current study demonstrated that metabolic vinyl chloride ...

  • Peroxygen Mediated Bioremediation of MTBE.

    ABSTRACT: Evidence is mounting, from laboratory and field studies, that oxygen plays a role in the bioremediation of methyl tertiary butyl ether (MTBE). Our experience with a number of commercial applications of peroxygen, in the form of Oxygen Release Compound (ORCâ), correlates the provision of enhanced aerobic conditions with enhanced MTBE biodegradation. Subsequent laboratory and field ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...

  • Inhibition of bacterial perchlorate reduction by zero-valent iron

    Perchlorate was reduced by a mixed bacterial culture over a pH range of 7.0–8.9. Similar rates of perchlorate reduction were observed between pH 7.0 and 8.5, whereas significantly slower reduction occurred at pH 8.9. Addition of iron metal, Fe(0), to the mixed bacterial culture resulted in slower rates of perchlorate reduction. Negligible perchlorate reduction was observed under abiotic ...

  • Heavy metal resistant anaerobic bacterial strains from brewery digester sludge

    This work focused on the study of the types of heavy–metal–resistant anaerobic bacteria from the sludge of a brewery wastewater treatment plant exposed to high concentrations of dissolved Cd (II), Cu (II) and Zn (II). Characterisations were carried out by polymerase chain reaction of the 16S rRNA gene of bacterial strain. Using special culture media, two types of strong heavy metal–resistant ...

  • Bioremediation of diesel oil - derwent island, national trust, united kingdom

    Introduction A spillage of red diesel oil (heating oil) from a holding tank located on Derwent Island in Lake Derwentwater, Cumbria, has been successfully treated using Microbac"s oil degrading bacterial cultures. The spill occurred in the Lake District National Park and a major concern was contamination of the lake water. The main problem associated with the work was access to the island ...

  • Bioremediation of fuel oil spill at a coastal naval air station in the united kingdom

    Introduction Approximately 1000 gallons of fuel oil had seeped from broken storage tank lines into the soil matrix beneath a boiler house. Oil was subsequently forced from beneath the boiler building by periodic heavy rainfall. The fuel oil migrated down a slope into a farmer"s field causing extensive damage to the vegetation and grazing area inhabited by sheep. ...

  • Biosurfactant production and its effects on solubilization activity of phenanthrene: a longitudinal study

    Pseudomonas facilis and Pseudomonasspp., isolated on the basis of its ability to grow on polycyclic aromatic hydrocarbon, was assayed for biosurfactant production (BP) potentials by measuring the surface tension (ST) of the culture supernatant at different time intervals. The strains in three levels of initial inoculum size (OD600 nm = 0.5, 1, 1.5) were added ...

  • Metagenomic approach to characterize soil microbial diversity of Phumdi at Loktak Lake

    Loktak, one of the largest freshwater lakes of India, is known for floating islands (Phumdi), being made up of a heterogeneous biomass of vegetation and soil. This ecological site represents an exclusive environmental habitat wherein the rhizospheric microbial community of Phumdi plays a key role in biogeochemical cycling of nutrients. A culture-independent whole genome shotgun sequencing ...

  • Isolation and growth kinetics of a novel phenol-degrading bacterium Microbacterium oxydans from the sediment of Taihu Lake (China)

    Seven phylogenetically diverse phenol-degrading bacterial strains designated as P1 to P7 were isolated from the industry-effluent dump sites of an industrial area near Taihu Lake, China. Through the 16S rDNA sequence analysis, these strains were widely distributed among five different genera: Rhodococcus (P1), Pseudomonas (P2–P4), Acinetobacter (P5), ...

  • Isolation of surfactant-resistant bacteria from natural, surfactant-rich marine habitats

    Environmental remediation efforts often utilize either biodegradative microbes or surfactants, but not in combination. Coupling both strategies holds the potential to dramatically increase the rate and extent of remediation because surfactants can enhance the bioavailability of contaminants to microbes. However, many surfactants permeabilize ...

  • DOD evaluates bioaugmentation for remediating low-pH aquifers

    The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

  • EOS Permeable reactive barriers successfully treat a large Trichloroethene plume - Case Study

    Historical use of trichloroethene (TCE) and other chlorinated solvents at a former au-tomotive parts manufacturing plant in Indiana resulted in a large groundwater plume, stretching approximately 2 miles from the site. TetraTech GEO evaluated sev-eral remedial alternatives and selected enhanced in situ bioremediation to reduce contaminant concentrations and eliminate continued plume migration at ...

  • The Effects of pH on Enhanced Reductive Dechlorination: Growth vs. Activity

    This past May at the International Symposium on In-Situ and On-Site Bioremediation sponsored by Battelle, I attended a session entitled “Microbial Ecology of Reductive Dechlorination and the pH Impact.” The presentation contained fascinating information about a seemingly well understood parameter, pH. Although a relatively simple parameter, the effect of pH on enhanced reductive dechlorination ...
