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