www.eppendorf.comand how these influence culture growth. As an example, we look at E. coli fermentation processes at bench scale. We track the biomass and nutrient concentrations during batch, fed-batch, and continuous fermentation runs. We explain different methods to analyze the process, including determination of biomass, growth

multimedia.3m.comMost E. coli (about 97%) produce beta-glucuronidase which produces a blue precipitate associated with the colony indicated by the blue to red-blue colonies. The top film traps gas produced by the lactose fermenting coliforms and E. coli. About 95% of E. coli produce gas, as indicated by colonies associated with entrapped
