Treatment of hydrocarbon-rich wastewater using oil degrading bacteria and phototrophic microorganisms in rotating biological contactor: Effect of N:P ratio

Performance of membrane bioreactor (MBR) systems for the treatment of shipboard slops: Assessment of hydrocarbon biodegradation and biomass activity under salinity variation

“…Although physicochemical methods have been successfully applied in the past [8,9], they impose several issues with regards to chemical consumption, high energy requirements and secondary pollution. Conversely, the use of biological treatments is becoming increasingly popular in the field of saline wastewater characterised by high organic content and petroleum hydrocarbons [5,[10][11][12][13][14][15], even if the presence of high concentrations of a separate oily phase usually requires proper pre-treatment [16]. In recent years, membrane bioreactors (MBRs) have been applied for saline wastewater treatment [17][18][19][20].…”

Efficiency of refinery sludge biodegradation using municipal wastewater and activated sludge and effect of hydrocarbon concentration on culturable bacteria community

“…Several solutions have been tried for treating these pollutants, but biological treatments using microorganisms remain the most suitable (Rahman et al 2002). All these biological processes, whether in continuous mode, batch mode or feed batch mode, have indicated that the rate of hydrocarbon biodegradation depends on several factors (Maki et al 1999;Tellez et al 2002;Chavan and Mukhreji 2008;Volpe et al 2009). Factors other than temperature, pH and dissolved oxygen are critical for a successful biodegradation process: these are essentially the competence of the inoculum used, the concentration of hydrocarbon and nutrients levels in the biodegradation medium (Rahman et al 2002;Tellez et al 2002;Margesin et al 2007;Hui et al 2007;Alfreider and Vogt 2007;Shokrollahzahed et al 2008).…”

A Decade of Burkholderia cenocepacia Virulence Determinant Research

“…have been described as plant pathogens (7,21,72), symbiotic rhizospheric or endophytic plant growth promoters (35,130), endosymbionts of fungi (5,56,70) and insects (77,144), and animal pathogens (31,59). They can degrade pollutants (25,30,83,84,147), fix nitrogen and solubilize metals for use by their symbiotic partners (25,73), produce compounds that protect their host-associated partners from pathogenic fungi, bacteria, protozoa, and nematodes (26,111,114), and even induce plant host defense mechanisms (37). B. cenocepacia can be associated with plants, including onions, sugarcane, maize, wheat, and legumes (8,96,112).…”
