Biodegradation pattern of hydrocarbons from a fuel oil-type complex residue by an emulsifier-producing microbial consortium

Isolation of hydrocarbonoclastic bacteria from bilge oil contaminated water

“…The obtained results are in agreement with the analysis of Nievas et al (2006Nievas et al ( , 2008 which higher concentration of aliphatics than aromatics in bilge oil waste. According to the observed kinetics of Nievas et al (2008), three main types of hydrocarbons i.e. n-alkanes, biodegradable UCM and recalcitrant UCM are present in BWOP.…”

Biodegradation of crude petroleum oil and environmental pollutants by Candida tropicalis strain

“…On the contrary, there are scanty information that yeasts is better crude oil degraders than bacteria (Walker et al, 1978). Additionally, a consortium of symbiotic bacteria or supporting materials can be used to enhance the biodegradation process as described by Tejo-Hernandez et al (2007); Nievas et al (2008); Hii et al (2009) ;Wang et al (2010) and Zhang et al (2010). Some reviews focused on the examination of factors, are including nutrients, physical state of the oil, oxygen, temperature, salinity and pressure influencing petroleum biodegradation rates, with a view to developing environmental applications (Atlas, 1981;Jonathan et al, 2003).…”

Biodegradation of diesel oil hydrocarbons enhanced with Mucor circinelloides enzyme preparation

“…Bioremediation, either as a spontaneous or as a managed strategy, is the application of biological processes for the clean up of hazardous chemicals present in the environment. There are many successful examples indicating that bioremediation is an effective and economically feasible means for treatment of oil contaminations (Chaillan et al, 2004;Vinas et al, 2002;Nievas et al, 2008). Nevertheless, an important concern still remains due to the toxicity of petroleum compounds, the large amounts of effluents, water and soil that need to be remediated in compliance with environmental standards, and the need to enhance the biodegradation of the more recalcitrant compounds (Nievas et al, 2008).…”

Microorganisms existing in contaminated environment can naturally attenuate pollutants but in active, engineered bioremediation, the addition of specific microbes or enzymes into the contaminated area may be required.…”
