Growth of Aureobasidium pullulans on waste water hemicelluloses

P Biely et al. Folia Microbiol (Praha). 1979.

Abstract

Strain Aureobasidium pullulans capable of utilizing hemicelluloses and xylan was cultivated on processed waste dialysis liquor from the production of viscose fibres, containing about 1.5% hemocelluloses. Basic conditions of biomass production were tested on a laboratory scale. The dialysis waste liquor adjusted with mineral acids to pH 4--5 and supplemented with 0.05% yeast autolyzate and 0.2% ammonium sulphate affords protein yields of about 0.8 g/l, corresponding to 4.0--4.5 g dry biomass. Biomass is isolated together with residual water-insoluble hemicelluloses which are not utilized by the microorganism. The total utilization of hemicelluloses attains about 70%.
