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 Sβ and Rβglucans in the mycelium of Aspergillus giganteus mut. alba depend on light within the range of selected light intensities: 0 W Β· m^β2^; 3 W Β· m^β2^; 10.6 W Β· m^β2^ at 20% glucose concentration in the nutrient medium. This species synthetises the highest amount of Sβglucans at the light intensity 10.6 W Β· m^β2^, and that of Rβglucans β at the intensity 3 W Β· m^β2^.
