摘要:
A method for locating hidden microorganism contaminated surfaces in industrial water systems is described and claimed. The method works by applying a solution or dispersion of a fluorogenic reagent in water to the hidden water contact surfaces of said industrial water system and allowing said fluorogenic reagent to react with any hidden microorganisms present, wherein said fluorogenic reagent is selected from the group of fluorogenic reagents that are known to react with microorganisms such that a fluorescent signal of said fluorogenic reagent is detectable in such a way as to make the detection of the fluorescent signal indicate that there are hidden microorganisms present on the water contact surfaces of the equipment and piping.
摘要:
A method is disclosed for controlling biofouling in an aqueous medium by treating the aqueous medium with an oil-in-water emulsion comprising an antimicrobial oil phase and at least one emulsifier. This method efficiently controls biofouling in the aqueous medium by specifically targeting the antimicrobial oil phase directly to biofilms, cell surfaces and cell aggregates in a concentrated form.
