<![CDATA[Rhodamin B is a dangerous synthetic dyes substances used as a fabric dye in thetextile industry. Biodegradation is one way that is used in the processing of liquid wasteRhodamin B. Biodegradation technique is leveraging the ability of microbial activitiesdegrade or eliminate pollutant compounds. The main objective of this research was toinvestigate the characteristic of bacteria that are capable of living on wastewater containingRhodamin B and the effectiveness of single and microbial consortium isolates to degradeRhodamin B on wastewater. The isolation of the bacteria was done by plating method and theidentification of the bacteria by using a Kit API 20E. Test of bacterial potential of RhodaminB dyes substance carried out in the Microbiology Laboratory, Biology Department, Facultyof Science, Udayana University. It was found in this research that five bacterial isolates wereobtained (Pseudomonas sp., Shigella spp., Stenotrophomonas sp., Pasteurella sp. dan Proteussp.). Pasteurella sp. had the highest percentage degrade effectiveness of 40.55%. Microbialpotential degrade Rhodamin B by Pasteurella sp. dan Proteus sp. results showed significantdifferences (P <0.05) to control.Keyword: bacteria, biodegradation, Rhodamin B]]>
