摘要：
A strain of the imperfect fungus Geotrichum candidum was selected for its ability to utilize the low-pH, high biochemical oxygen demand (BOD) waste generated by an Irish malt whiskey distillery. Growth of the organism on this complex medium, in both batch and continuous culture, showed a sequential assimilation of the major components with the most complete carbon assimilation (63.7%) being achieved in batch culture. Optimum temperature for the continuous culture of the organism was found to be 22°C; at this temperature and at a dilution rate of 0.125 h-1 a productivity of 2.24 g l-1 h-1 was obtained. Variations in organism morphology, produced by varying growth rate and nutritional or environmental factors, as well as the potential of the process for the production of single cell protein from carbohydrate-rich waste are discussed. © 1979 Springer-Verlag.
