摘要：

The effect of temperature on polysaccharide formation, cell growth, and morphology of A. pullulans was examined in both batch and continuous culture in the range 20°C to 36°C. Apart from minor deviations at both the extremes of temperature, the response was similar in both modes of cultivation. It was found that the temperature affects the fermentation significantly, with 24°C being the optimum for product formation. The variation in polysaccharide concentration with temperature may be a result of changes in the growth rate or morphology of the producer organism. A mechanism that may explain the observed results is suggested. © 1990.
