Evidence for n -alkane consumption and oxidation by filamentous cyanobacteria from oil-contaminated coasts of the Arabian Gulf

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

“…Maximum degradation of n-C16 and n-C19 by non-axenic cyanobacterial culture, Phormidium corium, from oil contaminated sediments was found to be 60 and 22.2%, respectively. In contrast, maximum consumption of n-C16 and n-C19 by non-axenic cyanobacterial culture, Microcoleus chthanoplasts, was only 20.6 and 4.1%, respectively [12]. Moreover, pure strains of Aphanocapsa sp., Plectonema tere- Fig.…”

“…In batch studies for hydrocarbon degradation using algalbacterial system, the hydrocarbon concentration employed was found to range from 400 to 10,000 mg/L and the degradation efficiency of n-alkanes was in the range of 22-98% [12,16,17,24]. The highest oil degradation in suspended growth system was reported for association of algae obtained from Oredege river (AS-45 and AS-47) with Rhodococcus sp.…”

“…In the coastal environment of the Arabian Gulf experiencing frequent oil pollution, oil degrading bacterial cultures are found to associate with cyanobacterial (blue-green algae) mats [11][12][13]. While some cyanobacterial cultures may play a direct role in hydrocarbon degradation, others may facilitate hydrocarbon degradation indirectly by providing surfaces for adherence of oil degrading bacterial cultures [12][13][14][15][16].…”

“…While some cyanobacterial cultures may play a direct role in hydrocarbon degradation, others may facilitate hydrocarbon degradation indirectly by providing surfaces for adherence of oil degrading bacterial cultures [12][13][14][15][16]. As a result of this association, the bacterial cultures are prevented from being washed-out even under turbulent conditions.…”

“…As a result of this association, the bacterial cultures are prevented from being washed-out even under turbulent conditions. The removal of high concentration of hydrocarbons by algal-bacterial system has been primarily reported in lab-scale batch studies [11,12,16,17]. However, there are no reports on the degradation of high concentration of complex non-aqueous phase liquids (NAPLs) using phototrophic microorganisms and bacterial cultures in RBC.…”
