Abstract
Spheroplasts ofMucor rouxii were prepared from mycelial and yeast-like cells by use of aPenicillium islandicum enzymatic complex. This enzyme preparation, which presents high chitosanase and chitinase activities, was produced by growingP. islandicum either on mycelial or yeast-like walls ofM. rouxii. The presence of magnesium sulfate as an osmotic stabilizer was critical to obtain high yields of spheroplasts from mycelial forms. In the case of yeast-like cells, pretreatment with β-mercaptoethanol followed by magnesium sulfate was essential for extensive spheroplast production.
