Controlling certain atmospheric conditions in a closed NGI processing chamber can reduce bioburden without disinfectants.
Chemical disinfectants pose risks to live cells. In a closed cell handling system, temperature and relative humidity (RH) were examined as a means to control microbes. Compared with biological safety cabinet conditions, lower RH and physiologic temperatures increased log reductions on polypropylene and steel surfaces. Environmental control can reduce the need for disinfectants.
