Although existing US NRT and RRT guidance covers important facts about bioremediation, existing material does not adequately define ...

  • Petrol Non-Combustibility Attribute - Case Study

    Petrol becomes non-combustible when sprayed with S-200 OilGone. Petrol non-combustibility and bioremediation demonstration in the presence of Mumbai Port Trust, India 18th February 2019. After four minutes the petrol treated with S-200 OilGone will not ignite. S-200 OilGone also renders the oil non-viscous – it will not stick to any surface. The treated fuel cannot sink and will always stay ...

  • Bioremediation Of Highway Spills On Sites With Shallow Underground Utility Lines

    Highway spills involving saddle tanks of trucks are fairly common and in such cases almost 104 gallons of diesel are released in the environment. Although excavation is a preferred method, bioremediation using AgroRemed is considered another option in many situations like this one in West Virginia where the underlying cables were likely to be damaged. At the end of bioremediation, the values of ...

  • Mechanisms and strategies of microbial cometabolism in the degradation of organic compounds – chlorinated ethylenes as the model

    The universal microbial cometabolism provides us with an effective approach to remove man-made xenobiotics. However, the cometabolic bioremediation of toxic organic compounds has not been widely initiated due to the obscure underlying fundamentals in the studies or applications of microbial cometabolism. This review summarizes the current research trends in mechanistic understanding of microbial ...

  • Removal of cadmium and zinc from contaminated wastewater using Rhodobacter sphaeroides

    Rhodobacter sphaeroides was used for bioremediation of wastewater polluted with cadmium (Cd) and zinc (Zn). The tolerance of the microorganism to selected heavy metals (HMs), as well as the effects of pH, temperature and inoculum size on the removal rate, was investigated. The remediation effects of R. sphaeroides were analysed at different initial concentrations of ...

  • Year-long effort secures California regulatory thumbs-up

    Working on behalf of client engineering firm URS Corporation, EOS Remediation brought the bioremediation product EOS® through unprecedented, custom testing to meet low-salt/low-metal regulatory standards for two California regulators. The result: a hard-to-secure regulatory approval for EOS®, which may be the only bioremediation product yet to meet these demanding state standards. EOS ...

  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • PAH Bioremediation

    The results of a recent bench-scale test confirmed the effectiveness of a special blend of CL Solutions’ microbes formulated for PAH bioremediation.  The test results showed that after two weeks, the total concentration of 15 PAH compounds decreased by 85% from a total of 358 mg/kg to 50.9 mg/kg.  Benzo(A)pyrene is often a most difficult PAH to remove. The test showed that the ...

  • Bioremediation of heavy metal contaminated aqueous solution by using red algae Porphyra leucosticta

    Bioremediation is an effective process for the removal and recovery of heavy metal ions from aqueous solutions. In this study, red algae Porphyra leucosticta was examined to remove Cd(II) and Pb(II) ions from wastewater through biological enrichment and biological precipitation. The experimental parameters that affect the bioremediation process such as pH, contact time and biomass dosage were ...

  • Biofilm Processes

    The biofilm process is a process which uses a biofilm for the purposes of filtration, bioremediation or barrier formation. A biofilm is a complex and heterogeneous matrix of microorganisms attatched to and growing on a surface. Biofilms are most often found on solid substrates that are exposed ...

  • Effect of a commercial alcohol ethoxylate surfactant (C11–15E7) on biodegradation of phenanthrene in a saline water medium by Neptunomonas naphthovorans

    Biodegradation of poorly soluble polycyclic aromatic hydrocarbons (PAHs) has been a challenge in bioremediation. In recent years, surfactant-enhanced bioremediation of PAH contaminants has attracted great attention in research. In this study, biodegradation of phenanthrene as a model PAHs solubilized in saline micellar solutions of a biodegradable commercial alcohol ethoxylate nonionic surfactant ...

  • Bioremediation Consulting Inc (BCI) develops an anaerobic chloroform-degrading culture

    BCI’s newest culture is a microbial mixture (consortia) which can transform chloroform (CF) to dichloroemthane (DCM), a transient intermediate which is then converted to a non-chlorinated product.  We have demonstrated that the culture can dechlorinate at least 10 ppm of chloroform. Dechlorinating Bacteria in BCI Cultures. To address single compounds or a mixture of chlorinated ethenes, BCI ...

  • Mythbusters: LNAPL & BOS 200

    By now you’ve heard of Trap & Treat BOS 200 and its uncanny ability to remediate LNAPL. If you’ve ever scratched your head and thought “bioremediation just can’t take place in an LNAPL environment, especially when it’s mixed with a product like BOS 200” you’re not alone. In fact, LNAPL plus BOS 200 seems as uncanny as, well, oil and water. Time to ...
