Effect of addition of bacterium Pseudomonas aeruginosa on biodecolorization of methylene blue by brown-rot fungus Gloeophyllum trabeum

Methylene Blue (MB) is one kind of textile dye from thiazine dyes that negatively impacts humans and the environment. Therefore, it very important to determine an effective method decolorize it. Brown-rot fungus Gloeophyllum trabeum can MB, but its ability was still relatively low required a long incubation time. In this study, effect adding bacterium Pseudomonas aeruginosa at 2, 4, 6, 8, 10 mL (1 ≈ 9.23 x 108 CFU) on decolorization MB by G. investigated. The particular 11.57%. addition 8 P. into culture showed maximum result 93.20% in liquid medium PDB for 7 days incubation. These results indicated could enhance biodecolorization trabeum, although not significant. Some metabolite products resulted degradation were azure A comes demethylation process, C derived process A, thionine C.
