Abstract

A yellow color in wastewater as a result of pharmaceutical manufacturing process can not be discharged directly to the environment because the abnormal color captures the attention of public and authority, even if the wastewater is harmless. Decolorization of wastewater that contained beta-carotene was investigated by using naturally microorganisms/indigenous microorganisms that have been present in the wastewater under aerobic condition. A particular medium (minimal medium) was used to determine microorganisms that were potential to decolorize yellow color in wastewater. As a result, there are more than one type microorganisms that could consume beta-carotene and have potency for decolorization. The effects of temperature (room temperature and 45 o C) and pH (acid, neutral, base) were studied for 3 – 4 days to obtain the optimal condition for microbial growth. The optimal condition was achieved at room temperature (24 o C) in basic condition (pH 9). Finally, decolorization process was monitored in artificial media for 3 – 4 days. As a result, 71 – 73% of yellow color was degraded and the wastewater is having similar visual color as water.
