New bactericide for biocide-resistant sulfate-reducing bacteria
Biocide-resistant sulfate-reducing bacteria (SRB) cause low efficacy of bactericides, and there is a high cost of killing the bacteria. A new bactericide, bisquaternary ammonium compound (BQA), has been synthesized in the laboratory. The performance of BQA was tested alone and in combination with metronidazol flagyl (ME). The results show that the biocide-resistant SRB induced by 1227 bactericide (dodecyldimethyl-benzyl ammonium chloride) can be controlled by BQA combined with ME. The equivalent curve indicates synergistic efficacy of BQA and ME. They work together to stifle SRB (especially the biocide-resistant bacteria) at low cost, not only in the laboratory, but also in the oil field, allowing reduced use of toxic commercial biocides.
