The effect of light on acid-soluble polysaccharide accumulation in Sclerotium rolfsii Sacc.

A light-stimulated increase in beta-1,3 glucan accumulation was observed for Sclerotium rolfsii Sacc. The acid-soluble polysaccharide accumulated in large quantities in 'white' light- and blue light-grown cultures. This polysaccharide also accumulated in both dark- and red light-grown cultures as well. However, the quantities were significantly lower when compared to the 'white' light- and blue light-grown cultures. A greater quantity of polysaccharide accumulated in red light-grown cultures than in dark-grown cultures.
