“…However, bacteria also play an important role in the degradation of hazardous dyes but fungi are superior to bacteria, due to adsorption of dyes by their hyphae as well as in the production of dye degrading enzymes [26]. Microbial degradation of hazardous dyes may be a good alternative among the conventional degradation of hazardous dyes and others pollutants.…”

Present investigation was carried out to study the fungal decolourization of azo (Acid red) and anthraquinonic (Basic blue) dyes by the fungus Aspergillus flavus. Decolourization of tested dyes was observed visually and studied through spectrophotometric analyses. Growing fungal cultures were filtered through Whatman filter paper No. 1 and filtrates were centrifuged at 6000 rpm for 5 minutes and supernatant was used for spectrophotometric observations, at absorbance 494 nm and 630 nm, for Acid red and Basic blue dyes, respectively. Decolourization/degradation was recorded by calculating the degradation percentage, using initial and final absorbance of the respective dye. The applied fungal species was found to be able to decolourize the mentioned dyes, as revealed by spectrophotometric analyses which showed a gradual decrease in the initial absorbance and increase in the mycelial yield of the used fungus. Decolourization/ degradation of dye were recorded to be 62%, for Basic blue and 77% for Acid red.

In the present study, dye decolorizing bacteria were isolated from water and soil samples, collected from textile industries in Jodhpur province, India. Two bacterial species namely, Bacillus pumilis and Paenibacillus thiaminolyticus were screened and identified based on biochemical characterization. The degradation efficiency of these two microorganisms was compared through optimization of pH, incubation time, initial dye concentration and inoculum size. B. pumilis and P. thiominolyticus were able to degrade 61% and 67% Red HE3B, 81% and 75% Orange F2R, 49.7% and 44.2% Yellow ME4GL and 61.6% and 59.5% Blue RC CT dyes of 800mg/l concentration respectively. The optimum pH and time were found to be 8 within 24 hours. The FT-IR analysis confirmed that microorganisms were able to degrade toxic azo dyes into a non-toxic product as proved through structural modifications to analyze chemical functions in materials by detecting the vibrations that characterize chemical bonds. It is based on the absorption of infrared radiation by the microbial product. Therefore, Bacillus pumilis and Paenibacillus thiaminolyticus are a promising tool for decolorization of dyes due to its potential to effectively decolorize higher azo dye concentrations (10-800 mg/L) and can be exploited for bioremediation.

“…These synthetic dyes and their effluents are recalcitrant to microbial degradation and causing problems in the usual biological degradation. Among the synthetic dyes, azo dyes, characterized by the presence of one or more azo groups (-N=N-), and anthrax-quinonic dyes represent the largest and most versatile group of dyes [6][7][8][9]. The synthetic dyes with azo group (e.g.…”

Present review highlights the role of fungi in biodegradation/decolourization of textile dyes and effluents. Though, fungi and bacteria both are the principal decomposer of xenobiotics in the environment but fungi are superior to bacteria in dyes degradation/decolourization due to their superiority in the production of dyes degrading enzymes and as absorbent. The present study focused on the achievements and advancement on the fungal degradation/decolourization of textiles dyes and effluents by the application of potent fungal strains. The biodegradation through fungi or myco-remediation of textile dyes and effluents using potential fungi is comparatively cheap and environmentally safe process, to decompose or mineralize the hardly or less degrading compounds of synthetic dyes. Fungi play an important role to degrade/decolourize the synthetic dyes through enzymes as well as by the absorption, adsorption and accumulation of colourants from the effluents.
