T.P. WEST AND B.R.‐H. STROHFUS. 1996. Cells of the fungus Aureobasidium pullulans ATCC 42023 were immobilized in sponge cubes and examined for their ability to elaborate the polysaccharide pullulan in relation to carbon source. It was found that fungal cells grown on corn syrup, sucrose or glucose as a carbon source could be immobilized in sponge cubes and that comparable cell weights and viable cell concentrations were immobilized. Independent of the carbon source tested, the immobilized fungal cells could be used at least three times for the production of polysaccharide. The immobilized A. pullulans cells elaborated the highest polysaccharide levels in the culture medium after 5–7 d of growth at 30°C.
