Effect of medium composition on amylase production by some starch‐degrading yeasts

The production of extracellular amylase activity by a number of recently described amyloytic yeast species, viz. Candida homilentoma, C. silvanorum, C. tsukubaensis, Cryptococcus flavus, Leucosporidium capsuligenum, Filobasidium capsuligenum and Trichosporon pullulans, was investigated. The effects on amylase secretion of pH, different carbon sources (glucose, maltose, dextrin, soluble starch) and of various nitrogen sources [yeast nitrogen base, yeast extract, corn steep liquor (CSL)] were compared for these yeasts.
