Bioremediation is more efficient and cost effective and less environmentally aggressive method for remediation of petroleum-contaminated soil. Researchers have been trying to harness the potential of microbial species for the bioremediation of contaminated soils. In present chapter, we will focus on recent...
Petroleum is the major source of energy for various industries and daily life. Releasing petroleum into the environment whether accidentally or due to human activities is a main cause of soil pollution. Soil contaminated with petroleum has a serious hazard to human health and causes environmental pro...
After 75 days operation,the contents of total petroleum hydrocarbon (TPH) in oil mud was decreased from 43.39 to 0.72g·kg -1 .The degradation rate of TPH reached 98.3% under optimal conditions. 展开 关键词: bio slurry reactor soil contaminated bioremediation ...
petroleum hydrocarbon and hexane in the early stage of bioaugmentation and in the later stages of biostimulation,with petroleum hydrocarbon as the most effective main carbon source,followed by hexane.The results indicated that metabolic capacities of soil microorganisms toward petroleum hydrocarbon are ...
Agricultural wastes, such as wheat bran and swine wastewater, were used for bioremediation of oil-contaminated soil. Two optimised strains that could degrade oil efficiently were selected. The result showed that the best ratio of strain A to strain B was 7:3. Swine wastewater could be a replac...
As the development of petroleum industry,the treatment of hydrocarbon-contaminated soil is concerned by researchers. Bioremediation technology was widely applied in in-situ and ex-situ operation because of the advantage of high efficient,no toxicity and no significant disturb on the ambient environment....
Biodegradation of petroleum hydrocarbon oil (14,000mgkg 1 ) were investigated in six biopiles batches, differing in the remediation strategy: bioaugmentation (selected consortium and kitchen waste were introduced), biostimulation (added with rhamnolipid, high-level, or low-level nutrient), and bioaugme...
The mechanisms for phytoremediation of petroleum contaminated soil using tall fescue (F. arundinacea L.) enhanced by PGPR were investigated by Hou et al. (2015). A total of 67.9% of hydrocarbons were successfully removed after 4 months of investigation. The authors also noted that petroleum ...
The use of an indigenous microbial consortium, pollutant-acclimated and attached to soil particles (activated soil), was studied as a bioaugmentation method for the aerobic biodegradation of pentachlorophenol (PCP) in a contaminated soil. A 125-l completely mixed soil slurry (10% soil) bioreactor ...
Citrate and malonate increase microbial activity and alter microbial community composition in uncontaminated and diesel-contaminated soil microcosms Petroleum hydrocarbons (PHCs) are among the most prevalent sources of environmental contamination. It has been hypothesized that plant root exudation of low mole...
