Optimisation of Manganese Peroxidase (MnP) Activity of Using Response Surface Method and Evaluation of Its Maillard Reaction Products Along with Lignin Degradation Ability.

Manganese peroxidase (MnP), a microbial ligninolytic enzyme which plays significant role in lignin and melanoidin degradation has gained much attention in the field of industry. In the present study, 15 ligninolytic bacteria were isolated from the soil sample of Similipal Biosphere Reserve (SBR) and screened for MnP activity. The most efficient MnP-producing bacterium HNB5 was evaluated for alkali lignin and maillard reaction products (MRPs) degradation and identified as using 16S rRNA sequencing.
