✦ Synopsis

Alkali-soluble glucans; AspergiUus giganteus mut alba; Glucans, alkali-soluble Glucans constitute a large proportion of the glucopolymers present in the cell walls of Aspergilh gigunteus mut. afba. This species is sensitive to light which controls some metabolic processes taking place in the cells [l-4]. In an earlier study, the occurrence of a quantitative dependence of the alkali-soluble glucans to light in the mycelium of A. gigunteus mut. ulbu was demonstrated [5,61.

From the mycelia of Aspergillus giganteus mut. alba grown in light and darkness two fractions of glucans were extracted. One of them was purified and characterized by its alkali-solubility and enzymatic degradation as polymer of b-D-glucose.

## Abstract The amounts of S‐ and R‐glucans in the mycelium of __Aspergillus giganteus__ mut. __alba__ depend on light within the range of selected light intensities: 0 W Β· m^βˆ’2^; 3 W Β· m^βˆ’2^; 10.6 W Β· m^βˆ’2^ at 20% glucose concentration in the nutrient medium. This species synthetises the highest a
