Abstract

Eurotium repens (Anamorph Aspergillus repens) was isolated from spoiled fruit (Fig). It reproduced sexually in presence of different sucrose concentrations up to 50% (w/v) (water activity, 0.79). While at high sucrose concentration 60% (w/v) (water activity, 0.75) it reproduced asexually. The concentrations of all detected amino acids were higher in teleomorph stage than anamorph stage except glycine. While a-aminoadipic acid and alanine were detected in teleomorph only. The extracellular secondary metabolites produced by teleomorph and anamorph stages were variable and different except epoxysuccinic acid and 2-pyruvylamino benzamide were produced by the two stages. Glycine, arginine and calcium chloride unlike glutamic acid, aspartic acid and alanine plays an important role in the induction of teleomorph stage formation at a concentration of 60 % (w/v) sucrose.
