The effects of a detergent product (Merix, Merima, Krusevac) o the production of aminoacids and monosaccharides and the proteolytic enzyme activity of the fungi Alternariae tenuis am Trichotecium roseum were examined. After incubation for 8 days the concentrations of all aminoacids except for isoleucine in the case of A tenuis and alanine in the case of T. roseum, were found to be lower it media with 1 % detergent than in the control media without acfcfeo detergent. However, progressively increasing concentrations o detergent from 0.01 to 1 % did not appear to affect consistently the proteolytic activity of either fungus in comparison with controls after 4 to 8 days incubation. After 4 days incubation the production of glucose: by A. tenuis was greater than the production of fructose ana concentrations of both monosaccharides were greater than with I roseum with or without detergent in the medium. It may be concluded that the metabolic activity of both fungal species is generally maintained in the presence of small quantities of the examined detergent.
