crude glycerol (cg) is an abundantly available and cheap by-product from biodiesel production. value-added applications for cg are highly wanted by industry and several processes such as the use of cg for enhanced oil recovery have been proposed. the aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (srb) indigenous to oil reservoirs using cg as substrate. th...

the objective of this research was to study the feasibility of a two stage continuous system employing anaerobic-aerobic microbial film for domestic wastewater treatment and the effect of iron on the behavior of sulfate reducing bacteria in anaerobic metabolism. a bench scale system with an anaerobic filter followed by aerobic fixed units used plastic media and was operated in up flow manner wi...

behaviors of simultaneous removal of no and so2 using the coculture of anaerobic denitrifying bacteria and sulfate reducing bacteria were investigated in a bench-scale biotrickling-filter. approximate 20 days were required to use the landfill leachate as the microbial seed to develop the biofilm on the surface of packing material. when the combined no/so2 removal biotrickling-filter was operate...
