Over the past five decades, the Indian textile industries have increasingly become a major user of azo dyes due to their wide range of applications. India is considered as one of the second largest producers of textiles in the world. Due to the rapid increase in the production rate of fabrics, the textile industry generates a huge amount of dyestuff and dyes in the environment. Continuous discharge of wastewater into the environment creates various types of pollution and also health impact on human beings. Azo dyes are toxic aromatic man-made compounds, which cannot be easily degraded by the indigenous microbes, and thus persist in ecosystems over a long period of time. In the current scenario, most wastewater treatment plants are obsolete and especially physico-chemical methods failed to achieve the satisfactory result because they are more expensive and produce a huge amount of sludge which again causes the secondary disposal problems. So, there is an urgent need to develop an alternative method to improve the degradation of azo dyes in an eco-friendly manner with low cost. In order to achieve the higher degradation efficiency in bioremediation technology, the present review mainly focuses on three important factors such as strain development for hyper-production of oxidoreductive enzymes by random mutagenesis, development of bacterial-fungal consortium and reusability of microbial cell cultures. Additionally, this review also compiles the effect of various physico-chemical conditions in decolourisation and degradation of azo dyes. [ABSTRACT FROM AUTHOR] |
