Ja. Perezpons et al., INDUCTION OF GLYCANOLYTIC ACTIVITIES BY STREPTOMYCES SP QM-B814 GROWING ON DIFFERENT GLUCOPOLYMERS, Biotechnology letters, 16(9), 1994, pp. 959-964
The actinomycete Streptomyces sp. QM-B814 is able to use polymeric glu
caris as sole carbon source by the induction of specific extracellular
enzymatic systems. Carboxymethylcellulose and barley beta-glucan were
the most effective inducers of endoglucanase activities towards beta-
(1,4) and mixed beta-(1,3)-(1,4) linkages. Avicelase activity was indu
ced by Avicel and carboxymethylcellulose. The higher activity towards
filter paper (cellulase) was measured in cultures growing in Avicel, c
arboxymethylcellulose, and barley beta-glucan. Laminarinase activity w
as induced only by laminarin and lichenan failed to induce significant
activity levels against any of the substrates tested.
