BIOREMEDIATION OF TEXTILE INDUSTRY EFFLUENT BY POTENTIAL INDIGENOUS FUNGI

Abstract

Wastewater from the textile industry is regarded to be one of the main causes of pollution owing to the high demand for textile products resulting in a proportionate rise in the production and application of synthetic dyes. Azo dyes are the most common group of synthetic dyes that make up 60–70% of over 10,000 dyes used in the textile industry (Ong et al., 2010). It is projected that about 2 percent and 10–15 percent of azo dyes are lost during manufacturing and dyeing procedures, and the release of these dyes into the environment creates an negative effect on the aquatic ecosystem because they are considered to be toxic to aquatic biota and are known to be carcinogenic to people. Effluent samples were collected from 6 textile factories in El-Giza governorate, Egypt, physicochemical characteristics (color, smell, temperature, pH, BOD, COD,TDS and TSS) of the various wastewater samples were determined using standard procedures according to (APHA, 2012). Results showed elevated levels of color, smell, temperature, and pH, BOD, COD, TDS and TSS in the 6 factories which indicated environmental impact of textile effluents. Five textile dyes, Remazol blue, Remazol red, Remazol yellow GR, Remazol black B and Orange 2RL (kindly supplied from Giza Spinning & Weaving
