%X A reasonable decrease has been found in almost all pollution indicators, which indicated emblems of natural bioremediation in real batik dye effluent from source (S1) to sink (S3). Among nine bacteria only FS5 exhibited the utmost biofouling potential in a microtiter plate assay with a noteworthy optical density of 0.629 ¡À0.042 (p>0.05). Furthermore, an endeavor was made to characterize the biofouling bacterial isolate (FS5) evaluating via 16S DNA sequencing. The present research based on the 16S DNA sequencing displayed that the isolate FS5 was similar to Bacillus sp. Extracellular polymeric substances (EPS) produced by FS5 were harvested and their dry weight (capsular 25.39 ¡À1.19, slime 21.73 ¡À1.40 and total 32.55 ¡À0.92 ¦Ìgml -1 ) and viscosity (169.24 ¡À 0.96 mPa) was measured. The total carbohydrates (TC) (70%) concentration in EPS was higher than total protein (TP) (30%) concentration. Thus, identifying an appropriate biological control agent against this biofouling bacterium is suggested as further course of action.
