Abstract:

Previous studies of oxidation-reduction potential ORP variation in monolayer Roux bottle cultures pointed out the need for data on pH and ORP patterns in simple spinner cultures. This information was desirable for optimizing conditions of growth in small 1-liter and 7.5-liter New Brunswick fermentors. Results of experiments in 250-ml centrifuge spinner vessels show that incubation of media prior to inoculation induces desirable qualities reflected in better growth. The importance of initial ORP values of the medium is discussed. The relationship of ORP levels to yield and longevity of cell growth is also considered. The ORP level of the medium at inoculation is shown to be affected by previous incubation. Author
