摘要

真菌菌株被广泛用于土壤、沉积物、地下水、地表水和生态系统的清洁。真菌中胞外酶的存在有利于纺织染料的生物修复。本研究对纺织染料工业废水的水质进行了观察,并对几种真菌对染料的修复能力进行了研究。从拉合尔纺织印染工业周围的污染区域收集了水样。在分离过程中,采用马铃薯葡萄糖琼脂(PDA)培养基验证真菌的生长情况。对真菌菌株进行纯化,在10倍和100倍放大镜下对真菌菌株进行形态学表征。鉴定出黑曲霉、曲霉、黄曲霉等真菌菌株。对每个真菌菌株施加4种染料胁迫。结果表明,曲霉是抗染料高胁迫最稳定、无毒、抗性最强的真菌之一。

Studies On the Role of Fungal Strains in Bioremediation of Dyes Isolated from Textile Effluents
Fungal strains are widely used for the cleaning of soil, sediments, groundwater, surface water, and theecosystem. The presence of extracellular enzymes in fungi facilitates the process of bioremediation of textile dyes. Thisstudy was conducted to observe the quality of water being released from textile dyes industries and also the capabilityof some fungal strains which can remediate these dyes by showing the tendency of their resistance. Samples of waterwere collected from the polluted area surrounding the textile dyeing industries in Lahore. In the process of isolation,Potato Dextrose Agar (PDA) medium was used to verify the fungal growth. Fungal strains were purified, and themorphological characterization of fungal strains was carried out at 10X and 100X by using a magnification microscope.The fungal strains, such as Aspergillus niger, Aspergillusoryzae, and Aspergillusflavus were identified. The stress offour types of dyes was given to each fungal strain. The results showed that Aspergillusoryzae was one of the moststable, non-toxic, and resistant fungal species against the high stress of dyes as compared to other species.
