Abstract

Lack of environmental friendly treatment of industrial effluent is a severe global problem. Microbial treatment may serve as potential technique to overcome the problem of environmental friendly management of industrial effluents. The present research was undertaken to find out potential indigenous fungal isolates/species from relevant industrial wastewaters and to explore their efficacy in mycoremediation of industrial effluent. Fungal species were isolated from textile, washing, dyeing, tannery and composite wastewaters, and efficient isolates were selected through screening against biobleaching of the effluent. Subsequently the selected fungal isolates were evaluated in mycoremediation of industrial effluent. Eleven fungal isolates were identified as species of Trichoderma, Penicillium, and Aspergillus. Finally, two species (M206 (Aspergillus sp.) and B102 (Penicillium sp.)) were used for mycoremediation. Significant improvement of biobleaching/bioremediation of treated effluent was noticed. After 5 days of treatment maximum 94 and 93% of turbidity, 48.45 and 38.14% of total solids (TS), 96.67 and 95.56% of total suspended solids (TSS), 36.98 and 36.12% of total dissolved solids (TDS) removal were recorded in treated effluent with prior grown fungal species of M206 and B102, respectively compared to control. Moreover, 72.93% chemical oxygen demand (COD) removal was also monitored by both species. Conversely, 93% turbidity and 89% TSS removal were recorded in fresh fungal spores suspension of M206, which were closer to the values obtained at 3 days prior grown treatment. Majority of the studied parameters suggested that the fresh fungal spores suspension exhibited superior performance in mycoremediation of effluent. Definitely fresh fungal spores suspension of M206 played superior roles in mycoremediation of the treated industrial effluent. Mycoremediation by fresh fungal spores suspension might be opened as a potential technique of industrial effluents treatment.

探索用于工业废水的真菌修复的潜在本土真菌物种

摘要

缺乏对工业废水的环保处理是一个严重的全球性问题。微生物处理可作为克服工业废水环境友好管理问题的潜在技术。本研究旨在从相关工业废水中找出潜在的本地真菌分离物/物种，并探索它们在工业废水的真菌修复中的功效。从纺织、洗涤、染色、制革和复合废水中分离出真菌菌种，并通过对出水生物漂白的筛选筛选出有效的分离菌。随后，在工业废水的 mycoremediation 中对选定的真菌分离物进行了评估。11 株真菌被鉴定为木霉属、青霉菌属和曲霉。最后，两个物种（M206 ( Aspergillus sp.) 和 B102 ( Penicilliumsp.)) 用于 mycoremediation。注意到处理后的流出物的生物漂白/生物修复的显着改善。处理 5 天后，记录了最大 94% 和 93% 的浊度、48.45% 和 38.14% 的总固体 (TS)、96.67% 和 95.56% 的总悬浮固体 (TSS)、36.98% 和 36.12% 的总溶解固体 (TDS) 去除率与对照相比，在处理过的污水中分别使用了先前生长的 M206 和 B102 真菌物种。此外，这两种物种还监测到 72.93% 的化学需氧量 (COD) 去除率。相反，在 M206 的新鲜真菌孢子悬浮液中记录到 93% 的浊度和 89% 的 TSS 去除率，这更接近于生长处理前 3 天获得的值。大部分研究参数表明，新鲜真菌孢子悬浮液在污水的菌体修复中表现出优异的性能。M206 的新鲜真菌孢子悬浮液在处理后的工业废水的真菌修复中发挥了卓越的作用。新鲜真菌孢子悬浮液的真菌修复可能会成为工业废水处理的潜在技术。
