Fungal Remediation of Nematocyte with Fluopyram Active Ingredient by P. frequantans and its Mortality Effect on D. magna

Abstract

In this study, to understand the bioremediation efficiency of Penicilium frequantans soil fungus used as a useful tool for bioremediate a fluopyram nematocide with important environmental parameters such as chemical oxygen demand (COD) and total organic carbon (TOC) studied. Additionally, mortality tests were performed for treated and untreated media with D. magna to gain additional knowledge about the toxic effect of this pesticide after bioremediation step. According to the results of the study, P. frequantans performed high COD and TOC reduction rates of fluopyron nematocide as 90 % for both parameters in 6 and 7 days respectively. This means P. frequantans is a suitable tool for bioremediating this kind of nematocides. According to the D. magna mortality test results, TOC and COD values of pesticide dereeased, mortality rates increased by the reason of chemical structure and side products of pesticide.
