Summary: | The ability of fungus Mucor racemosus Fresenius to decompose high
concentration of commercial detergent (MERIX, Henkel, Serbia) was
investigated in this study. Fungus was cultivated in liquid growth medium by
Czapek with addition of detergent at concentration 0.5% during 16 days. The
biochemical changes of pH, redox potential, amount of free and total
organic acids, and activity of alkaline phosphatase were evaluated by
analysis of fermentation broth. Simultaneously, biodegradation percentage
of anionic surfactant of tested detergent was confirmed by MBAS assay. At
the same time, the influence of detergent on fungal growth and total dry
weight biomass was determined. Detergent at concentration 0.5% influenced
on decreasing of pH value and increasing of redox potential as well as
increasing of free and total organic acids. Enzyme activity of alkaline
phosphatase was reduced by detergent at concentration 0.5%. The fungus was
decomposed about 62% of anionic surfactant during 16 day. Due to fungus was
produced higher dry weight biomass (53%) in relation to control. [Projekat
