Eleven isolates of sulphate-reducing bacteria (SRB) were isolated from soil contaminated with crude oil derivatives and petroleum-refining wastewaters and used to investigate the effectiveness of carbon reduction and biotransformation of phosphogypsum. One of the isolates (culture no. 10) was found to be very effective with 90% carbon reduction (measured as COD) and the simultaneous biotransformation...
The paper presents the activity of anaerobic bacterial communities isolated from soil polluted by aircraft fuel on distillery decoctions with phosphogypsum. The microorganisms were selected using the microcosms method, and then enriched on Postgate medium with ethanol. The isolated communities became the inoculum to establish a culture on potato and rye distillery decoctions. The obtained results...
The biotransformation of phosphogypsum in cultures of sulfate-reducing bacteria (SRB) isolated from crude petroleum-refining wastewaters or purified using activated sludge method was studied. Selection was with the microcosms method on Postgate and minimal medium with different carbon sources, Emerson medium and petroleum-refining wastewaters. Highest hydrogen sulfide production, in excess of 500...
