In order to search the degradability of kraft lignin, the potential bacterial strains Bacillus subtilis (GU193980) and Klebsiella pneumoniae (GU193981) were isolated, screened and applied in axenic and co-culture conditions. Results revealed that mixed culture showed better decolorization efficiency (80%) and reduction of pollution parameters (COD 73% and BOD 62%) than axenic culture. This indi...

The kraft process is applied to wood chips for separation of lignin from the polysaccharides within lignocellulose for pulp that will produce a high quality paper. Black liquor is a pulping waste generated by the kraft process that has potential for downstream bioconversion. However, the recalcitrant nature of the lignocellulose resources, its chemical derivatives that constitute the majority o...

Total reduced sulfurs (TRS) include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3) and dimethyl disulfide (CH3S2CH3) and are referred to as noncondensible gases. They are part of a well-known environmental problem afflicting pulp mills exploiting the Kraft pulp mill process. These sulfur compounds are formed in the Kraft pulping process and come in co...
