WebAfter the glycerol from the batch phase is consumed, feed glycerol for 1 hour at 20 g glycerol/Liter of initial fermentation broth. After 1 hour, inject methanol to a final concentration of 1.5 ml MeOH/L. At the same time the bolus of MeOH is added, initiate a linear ramp of the glycerol feed rate from 20 g/L/h to 0 g/L/h over 3 hours. WebFermentation tubes containing brilliant green lactose bile broth are inoculated with medium from the tubes showing a positive result in the presumptive test. Inoculation should be performed as soon as possible afte r gas formation occurs. The inoculated tubes are incubated for 48 + 3 hr at 35 + 0.5EC.
