        Degradation of Sulfonated Azo Dyes by the Purified Lignin Peroxidase from Brevibacillus laterosporus MTCC 2298

        Sushama S. Gomare,Jyoti P. Jadhav,Sanjay P. Govindwar 한국생물공학회 2008 Biotechnology and Bioprocess Engineering Vol.13 No.2

        Lignin peroxidase (EC 1.11.1.14) was purified from the Brevibacillus laterosporus MTCC 2298 by ion exchange chromatography. The Km value of the purified lignin peroxidase (using n-propanol as substrate) was 1.6 mM. The MW of purified enzyme determined with the help of MW-standard markers was approximately 205 kDa. Purity of the enzyme was confirmed by native polyacrylamide gel electrophoresis (PAGE) and the activity staining using a substrate L-DOPA. Sulfonated azo dyes such as Methyl orange and Blue-2B were degraded by the purified lignin peroxidase. Degradation of the dyes was confirmed by HPLC, GC-MS, and FTIR spectroscopy. The mainly elected products of Methyl orange were 4-substituted hexanoic acid (m/z = 207), 4-cyclohexenone lactone cation (m/z = 191), and 4-isopropanal-2, 5-cyclohexa-dienone (m/z = 149) and for Blue-2B were 4-(2-hexenoic acid)-2, 5-cyclohexa-diene-one (m/z = 207; M - 1 = 206) and dehydro-acetic acid derivative (m/z = 223).
