Biocompatible Removal of Tannin and Associated Color from Tannery Effluent using the Biomass and Tannin Acyl Hydrolase (E.C.3.1.1.20) Enzymes of Mango Industry Solid Waste Isolate Aspergillus candidus MTTC 9628

Abstract:
Tannins, the important recalcitrant natural polymers released along with tannery effluents limits their treatment and reuse. The currently employed treatment methods failed to degrade them completely. An attempt has been made specifically to treat tannin and remove associated color from the tannery effluent. The biomass of mango industry solid waste isolate Aspergillus candidus MTTC 9628 and the tannase enzyme from this organisms were found to degrade and thereby reduce the tannin content of the tannery effluent resulting in the decolourisation of the effluent. The results obtained after treatment with the immobilized tannase enzyme also showed considerable reduction in effluent tannin content and hence the color of the effluent. However, it is observed that the whole organisms treatment have a fundamental advantage over enzymatic treatment as they transform a broad range of compounds resulting decrease in Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and other physicochemical characteristic values. This present works reveals that these undegradable tannins can be specifically removed by enzymatic treatment. Development of suitable treatment facility employing tannase enzymes could be adapted at laboratory and industrial level treatment thereby making it suitable for further use.
