Rapid industrialization has necessitated the manufacture and use of different chemicals in day to day life. Water is life but now-a-days due to advancement in industrialization, it a spoiling a lot. In the present study, an attempt was made to examine the isolation and identification of Bacillus species from marine soil, Nagapattinum seashore, Tamil Nadu, India. Dyes are collected from in around Tirupur dyeing unit, Tamil Nadu, India namely Reactive purple, Malachite green, Reactive red M5B, Reactive pink MB. Out of 5 Bacillus isolated, 2 of them are selected for our study based on the decolourization screening test. Percentage of dye degradation and physical and chemical parameters were optimized. In dye samples TS,TDS,TSS, calcium, phosphorus were estimated. It was therefore calculated that Bacillus subtilis is an remedial strain for the dye effluent treatment in Reactive pink dye degradation. Compared to Bacillus cereus the Bacillus subtilis was showed maximum dye degradation 70.8% at PH 7, Temperature 37°C and carbon (glucose) nitrogen(yeast extract) for Reactive pink MB. Dye decolourization can use measured in terms of optical density.

Key words: Marine soil, Dye, B.subtilis, B.cereus, Total solids, Total dissolved solids, Total suspended solids.
