Kraft lignin biodegradation by Novosphingobium sp. B-7 and analysis of the degradation process

► The first report on kraft lignin degradation by bacterium of genus Novosphingobium. ► Novosphingobium sp. B-7 secreted extracellular MnP and Lac to degrade lignin. ► Kraft lignin was depolymerized by Novosphingobium sp. B-7 first and then degraded.
