✦ Synopsis

The production of xylanase in the presence of various polymeric substrates was studied. Among the polymeric substrates, xylan was the best inducer of xylanase by V. albo-atrum. Other cellulolytic enzymes such as glucanase and P-glucosidase were synthesized in smaller quantities. The process of degradation indicated that xylanase behaved as typical endo enzyme causing first production of high , mol. wt. products. Studies on xylan medium indicated that V. albo-atrum produced at least three enzymes which degrade xylan.

Methods

Verticillium albo-atrum (isolate 454,51) was obtained from Centraalbureau Voor Schimmel Cultures (Baarn, Netherlands) and was maintained on potato dextrose agar slants by regular transfers. Cellulose

## Abstract The radical polymerization of acrylic acid and sodium 4‐styrenesulfonate in the presence of chitosan as a template gives insoluble products, identified as the polyelectrolyte complexes chitosan‐poly(acrylic acid) and chitosan‐poly(4‐styrenesulfonate). Kinetic results do not permit to pr
