Inactivation of escherichia coli by photochemical reaction of ferrioxalate at slightly acidic and near neutral pHs

Article Abstract:

Fenton reactions as well as Fenton type reactions have widely been used as advanced oxidation processes in creating non-biodegradable wastewater but they have their limitations like formation of iron sludge when ferrous ions have to be continuously supplied. Illumination of the system by UV-visible light was suggested to overcome these limitations and it was found that it may be a workable a solution for treatment of water or wastewater in remote areas.

Protective effects of organic acids on survival of Escherichia coli 0157:H7 in acidic environments

Article Abstract:

A study was conducted to investigate the killing of Escherichia coli 0157:H7 strains in the presence or absence of selected organic acids, using glyconic acid as a noninhibitory low-pH buffer. It was observed that acetic, malic, and L-Lactic acids can have protective effects on the survival of E. coli, when compared to pH.

Extracellular iron reduction is mediated in part by neutral red and hydrogenase in Escherichia coli

Article Abstract:

The object of this study is to examine the mechanism by which neutral red anode acts as an electron mediator to Escherichia coli metabolism and reduction of iron. This study also discusses the analogies between microbial anode and metal reduction.
