Bacterial Lignin Peroxidase: A Tool for Biobleaching and Biodegradation of Industrial Effluents
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 1
Abstract
Lignin, the nature’s plastic is the major pollutant from paper-pulp mill effluent due to its intense unaesthetic brown color, hydrophobicity and poor mechanical properties, tends to be a recalcitrant compound. Textile dyebased industries release colored effluents due to presence of large amount of mixture of dyes which is also hazardous. Microbial extracellular lignin peroxidase enzymes have a potential to degrade lignin and a wide range of complex aromatic dyestuffs. From various environmental niches eleven isolates were screened for lignolytic activity, out of which two bacterial isolates Pseudomonas aeruginosa and Serratia marcescens were able to decolorize 44% to 49% of lignin. The studies on biobleaching of paper-pulp mill effluent gave 60% to 75% color reduction and in case of textile dye- based effluent 50% to 58% decolourization was observed. The heterogeneous combination of lignin peroxidases from mixed consortia gave 80% to 85% color reduction in treatment of paper-pulp mill effluent and 70% to 75% decolourization in treatment of textile dye-based effluent which is significantly high. This system of lignin peroxidase may be efficiently used in biobleaching and biodegradation of effluents from respective industries.
