Residual malachite green dye is often pollutes the environment. Therefore, in recent years, the use of microbial agents to decolorize indusbry textile dye is a very popular alternative. This study was designed to evaluate the collection of Bacillus amyloliquefaciens at Pelita Harapan University to decolorize malachite green dye. Decolorization ability of B. amyloliquefaciens was evaluated using solid and liquid media, decolorization process is also analyzed by TLC and uv-vlS spectrophotometer. The results showed that some strains of B.amyloliquefaciens decolorize MG in solid and liquid media, so it could indicate that B.amyloliquefaciens can be used as environmentally friendly remediation agent for malachite green dye (MG). The results also showed that malachite green biodegradation process produces several products metabolites when it was analyzed by UV-VIS spectrophotometer and TLC.
