Degradasi Direct Violet 35 menggunakan Pseudomonas aeruginosa
Degradation process of Direct Violet 35 has been carried out by Pseudomonas aeruginosa through azoreduktase enzyme activity. In this study, the factors that affect process of degradation were investigated including contact time, number of bacterial colonies, initial dye concentration, and pH of dye...

| Summary: | Degradation process of Direct Violet 35 has been carried out by
Pseudomonas aeruginosa through azoreduktase enzyme activity. In this study, the
factors that affect process of degradation were investigated including contact time,
number of bacterial colonies, initial dye concentration, and pH of dye solution.
The process of Direct Violet 35 dye degradation was analyzed by UV-Vis
spekrofotometer.
The results showed that the degradation of Direct Violet 35 dye with
Pseudomonas aeruginosa is optimum with the time of contact 48 hours, bacterial
colonies number of 2,89 x 1010 cfu, initial dye concentration 15 mg/L, and pH 6.5.
The result of UV analysis indicated that the dye structure changed after the
degradation process. |
