The present invention provides a method of treating an aqueous system for biocide control, by adding an acidified solution that includes monoalkyldithiocarbamate salt and alkyl isothiocyanate to an aqueous system. A biocide feed system is also provided that is configured to generate a reproducible level of alkyl isothiocyanate. The method and system provide effective levels of alkyl isothiocyanate for rapid biocidal activity, along with levels of monoalkyldithiocarbamate salt which can decompose to form additional alkyl isothiocyanate and provide longer-term biocidal activity.
The activity of β-lactam antibiotics is compromised by metallo-β-lactamases (MBLs). Herein, a series of dithiocarbamate derivatives were designed and synthesized. Their antibacterial activities were tested in combination with meropenem (MEM) against several MBL (NDM and IMP type)-producing clinical isolates. Clinical isolates harboring NDM-1 and IMP-4 became susceptible to MEM when it was combined
