Discoloration of Textile Liquid Waste by Indigenous Bacteria

The research about decolorization of remazol blue pigment by using indigenous bacterial isolate has been conducted since March July 2019. This research was conducted to analyze the efficiency of the change remazol blue pigment used on the most textile industry. It was through the process of decolorization by using Bacillus spp, that is indigenous bacterial isolate from batik waste water. The method used in this research is decriptive. The waste used was artificial waste and it used remazol blue pigment with 50 mg/L, 100 mg/L and 200 mg/L concentrate. The process of decolorization was done by using submerged fermentation technic on statist condition through 7 day-incubation. The result of this research shows that the eficiency of decreasing colour and COD (Chemical Oxygen Demand) reachs 80-90 % on the concentrate of pigment 100 mg/L.
