BIODEGRADATION OF TEXTILE DYE USING MARINE MICROORGANISM AND SCREENING FOR LACCASE PRODUCTION

A. N. Sruthi* and T. Mekala

ABSTRACT

Textile dye industry waste is one of the most serious problem in the environment. The dye wastes are severely deleterious to surface water bodies. In the present study, an attempt was made to analyse the isolation and identification of dye degrading bacteria from marine water muthupettai mangrove forest, Tamil nadu. India. Dye was collected from home textile industry kumbakonam dyeing unit, Tamil nadu, India. There screening test percentage of dye degradation at different concentration were analysed. It was therefore calculated that Staphylococcus is an remedial strain for the dye effluent treatment. Dye decolouriztion was measured in terms of optical density. Staphylococcus aureus was screened for laccase production in Luria Bertani agar and was observed by broen colour zone formation around the colonies. Laccase (E.C.1.10.3.2, benzenedial oxygen oxyreductase) are also called as “Blue Enzyme” because they are multinuclear copper containing enzymes. They can catalyse the oxidation of various organic and inorganic compounds.

Keywords: Marine water, Textile dye, Decolourization, Laccase.
