• Mutualistic dialysis culture of Streptococcus lactis, which is valuable as a dairy starter, and Candida utilis, which is valuable as single cell protein, was investigated in a batch fermentation system. The bacterium and the yeast were inoculated into separate fermentors connected by an intermediate dialyzer, the membranes of which allowed diffusional exchange of solutes. Lactose fed into the bacterial culture was fermented to lactic acid, which was dialyzed into the yeast culture and consumed so as to relieve product inhibition of the bacterial culture. Consequently, the bacterial cell concentration more than doubled in comparison with a nondialysis control, and yeast cells were produced as byproduct. Although the acid production rate by the bacterium was much faster than the acid consumption rate by the yeast, the primary limiting factor of the process apparently was the solute exchange rate across the membrane.
