Chloromethyl-methylisothiazolone (CMIT/MIT) biocide is used for microbial control in industrial water treatment applications. It is effective versus various types of bacteria, algae and fungi. This paper will provide results of planktonic and biofilm efficacy studies with CMIT/MIT biocide versus various strains of Desulfovibrio.
Observations and guidelines to conduct hydrostatic pressure tests of pipelines and/or process equipment. Concerns for hydrostatic pressure tests relate to the water itself, including any suspended solids, dissolved oxygen, or any Sulfate Reducing Bacteria (SRB) or Acid Producing Bacteria (APB) present in the test water.
A preliminary evaluation of the use of Surface Enhanced Raman spectroscopy (SERS) to monitor Biofilm. SERS was used to monitor the growth of Desulfovibrio vulgaris and Desulfovibrio desulfuricans on UNS S30400 stainless steel samples in-situ from pre-inoculation through the initial hours of growth at 37 °C and atmospheric pressure.
Biocides and corrosion inhibitors can decrease corrosion in stagnant and flowing systems. We used 1 ml syringe columns packed with 60 carbon steel beads (55 mg each), which were continuously injected with the effluent of an sulfur reducing bacteria continuous culture chemostat, to monitor corrosion under flow conditions.
