In this study, we aimed to find out the biodegradation efficiency of some soil fungi types on herbicide acetochlor with acetochlor active material, chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total organic carbon (TOC) parameters. We also try to determine the population dynamics of these fungi via turbidity. The fungi cultures were isolated from agricultural field in in Thrace region of Turkey. Each fungi enriched in malt extract broth media and 1 mL of these enriched media was inoculated into 100 mL of acetochlor solutions that suggested for using application concantrations in agricultural field for farmers (11000 mg L) for sunflower and corn agriculture. Bioremediation results of acetochlor have shown different results according to the types of fungi. Our results indicate that Tolypocladium geodes and Cordyceps cicadae might be used in acetochlor bioremediation with a significant acetochlor, COD, TOC and BOD reduction and can be used for rehabilitation of agricultural fields or receiving environments for removal the opposite effects of acetochlor or other herbicides.
在本研究中，我们旨在通过乙草胺活性物质、化学需氧量（COD）、生化需氧量（BOD）和总有机碳（TOC）参数来找出某些土壤真菌类型对除草剂乙草胺的生物降解效率。我们还试图通过浊度来确定这些真菌的种群动态。真菌培养物是从土耳其色雷斯地区的农田中分离出来的。每种真菌在麦芽提取物肉汤培养基中富集，然后将1毫升这些富集培养基接种到100毫升乙草胺溶液中，该溶液的浓度为农民在向日葵和玉米种植的农田中建议使用的施药浓度（11000毫克/升）。乙草胺的生物修复结果因真菌类型而异。我们的结果表明，地托霉和蝉花虫草可用于乙草胺的生物修复，能显著降低乙草胺、COD、TOC和BOD，可用于修复农田或受纳环境，以消除乙草胺或其他除草剂的负面影响。
