Textile wastewater contains huge quantities of nitrogen (N)‐containing azo‐dyes. Irrigation of crops with such wastewater adds toxic dyes into our healthy soils. One of the ways to prevent their entry to soils could be these waters after the dyes' biodegradation. Therefore, the present study was conducted to evaluate the impact of textile dyes on wheat growth, dye degradation efficiency of bacteria‐fungi consortium, and alleviation of dye toxicity in wheat by treatment with microbial consortium. Among dyes, Red‐S3B (3.19% N) was found to be the most toxic to germination and growth of seven‐day‐old wheat seedlings. Shewanella sp. NIAB‐BM15 and Aspergillus terreus NIAB‐FM10 were found to be efficient degraders of Red‐S3B. Their consortium completely decolorized 500 mg L⁻¹ Red‐S3B within 4 h. Irrigation with Red‐S3B‐contaminated water after treatment with developed consortium increased root length, shoot length, root biomass, and shoot biomass of 30‐day‐old wheat seedlings by 47, 18, 6, and 25%, respectively, than untreated water. Moreover, irrigation after microbial treatment of dye‐contaminated water resulted in 20 and 51% increase in shoot N content and N uptake, respectively, than untreated water. Thus, co‐inoculation of bacteria and fungi could be a useful bioremediation strategy for the treatment of azo‐dye‐polluted water.

共同接种细菌和真菌的生物降解可减轻Red-S3B对小麦生长和氮吸收的不利影响

纺织废水中含有大量的含氮氮偶氮染料。用这种废水灌溉农作物会在我们的健康土壤中添加有毒染料。防止染料进入土壤的一种方法可能是染料生物降解后的这些水。因此，本研究旨在评估纺织品染料对小麦生长的影响，细菌-真菌财团的染料降解效率以及通过微生物财团的处理减轻小麦的染料毒性。在染料中，发现Red-S3B（3.19％N）对七日龄小麦幼苗的发芽和生长最具毒性。希瓦氏菌 发现NIAB-BM15和土曲霉NIAB-FM10是Red-S3B的有效降解剂。他们的财团对500 mg L ^-1完全脱色红色-S3B在4小时内。经过发达的财团处理后，用Red-S3B污染的水灌溉比未处理的水分别使30天龄小麦幼苗的根长，茎长，根生物量和茎生物量分别增加47％，18％，6％和25％。 。此外，与未处理的水相比，经过微生物处理的染料污染的水经过灌溉后，苗中的氮含量和氮吸收量分别增加了20％和51％。因此，细菌和真菌的共同接种可能是处理偶氮染料污染水的有效生物修复策略。
