Abstract
An apparatus and method for microbial growth by fermentation with the apparatus including a plurality of vessels connected in series. The fermentation vessels include a prefermenter which feeds microorganism-containing effluent continuously to an intermediate fermenter in which the majority of fermentation is conducted. The intermediate fermenter feeds microorganism-containing effluent to a secondary fermenter in which portions of the feedstock are consumed substantially to extinction. Preferably heat exchangers for each of the vessels are connected in series and an oxygen-containing gas which is partially depleted of oxygen can be fed from the intermediate fermenter to the other fermenters in series.
