| Abstract: | Semi-continuous tests of lactic fermentation of whey by Lactobacillus buigaricus were carried out using a mixture of hydrolysed milk and vitamins. The volume of the Inoculum varied from 20% to 50% of the reactor working volume. A Monod-like equation correlates the lactic acid productivity and the volume fraction of inoculum.The authors are with the Centro de Desenvolvimento Biotecnológico de Santa Catarina (Biotechnological Development Centre of Santa Catarina), R.
