Abstract
The aim of this study was to find out, among grate variety of fungi species from wastewater these which are resistant to effects of detergent and its component, ethoxyl-oleyl-cetyl alcohol and sodium tripolyphosphate. On inoculated fungi specie grown in vitro condition, in the presence of mentioned pollutant, the metabolic changes of bioproduction of different organic compounds, in various aging step of fungi, have been investigated. The results indicated sig-nificant changes in bioproduction of amino ac-ids and proteins of Aspergillus niger cultivated in the presence of detergent and its component, compared with control experiment. The results suggest that bioremediation by Aspergillus ni-ger are promising for biodegradation of deter-gents in aquatic systems.
Highlights
Detergents are formulations designed to have cleaning/solubilisation properties
This paper conducted a research on influence of detergent Merix (Merima, Kruševac, Serbia) and its components on metabolic activity of fungi Aspergillus niger
The fungi was grown in the liquid nutrient medium according to Czapek, where 1% of detergent or its component was added, during the incubation period of 4-8 days after inoculation
Summary
Detergents are formulations designed to have cleaning/solubilisation properties These formulations consist of surface-active agents (surfactants) together with subsidiary components including builders (e.g. tripolyphosphate), boosters, filters and auxiliary compounds. Surfactants are a group of organic compounds achieved by chemical synthesis and characterized for specific behavior in solution that makes them especially suitable for many human activities. Surfactant is an abbreviation for a surface-active agent that refers to its ability to reduce the interfacial tension between two phases. This behavior is caused by the molecular composition in the surfactant, which has a hydrophobic part, composed of alkyl chains, and another part that is an anionic or hydro-. The principal criterion for the ecological behavior of surfactant is their biodegradability [3]
