We evaluated the efficacy of different neutralizing solutions for use in disinfectant efficacy assays. Our approach used comparisons between the recoveries of low inocula in different treatment populations. The challenge organisms employed were those described by the AOAC for use in determining germicidal, tuberculocidal, sporicidal, and fungicidal activity of disinfectants. Neutralizer efficac...

in the present study, the potential of a bacterial consortium of enterobacter cloacae and pseudomonas sp. (ercppi-2) for microbial enhanced oil recovery was investigated. various mechanisms of enhanced oil recovery (eor) as a result of using ercppi-2 and its metabolic products were studied in detail. the obtained results showed that under simulated reservoir conditions, interfacial tension redu...

  Background : The development of microbial resistance to the existing anti-microbial agents has become a real challenge and a serious problem facing patients suffering from skin infections. Seeds of Nigella sativa have been used for a long time in folk medicine for the treatment of skin infections. Production of new potent agents is urgently needed, especially for hospitals and health care cen...
