The potential application of fungus Trichoderma harzianum Rifai in biodegradation of commercial detergent (Merix, Henkel, Serbia) was the focus of this study. The fungus was isolated from wastewater samples of the Rasina River, downstream from where the industrial wastewaters of the plant Henkel (Kruševac, Serbia) discharge into the river. The fungus was cultivated in liquid growth medium by Czapek with addition of detergent at a concentration of 0.3% during 16 days. Analysis of fermentation broth evaluated the chemical and biochemical changes of pH, redox potential, activity of alkaline and acid invertase as well as activity of alkaline protease. In addition, the influence of detergent on fungal growth and total dry weight biomass was determined. At the same time, detergent disappearance in terms of methylene blue active substances in the medium was measured. The detergent at a concentration of 0.3% influenced significant decrease of pH value and increase of redox potential. The detergent showed inhibitory effect on acid invertase activity and stimulatory effect on alkaline invertase and protease activity. The fungus decomposed about 74.24% of tested detergent during 16 days, but total dry weight biomass reduced about 20% in relation to control.
