Modification of kraft lignin (KL), traditionally uses harsh and energy-demanding phys. and chem. processes. In this study, the potential of the bacterial laccase CotA (spore coating protein A) for oxidation of KL under mild conditions was assessed. Thereby, the efficiency of CotA to oxidize both softwood and hardwood KL of varying purity at alk. conditions was examined For the resp. type of wood, the highest oxidation activity by CotA was determined for the medium ash content softwood KL (MA_S) and the medium ash content hardwood KL (MA_H), resp. By an up to 95% decrease in fluorescence and up to 65% in phenol content coupling of the structural lignin units was indicated. These results correlated with an increase in viscosity and mol. weight, which increased nearly 2 and 20-fold for MA_H and about 1.3 and 6.0-fold for MA_S, resp. Thus, this study confirms that the CotA laccase can oxidize a variety of KL at alk. conditions, while the origin and purity of KL were found to have a major impact on the efficiency of oxidation Under the herein tested conditions, it was observed that the MA_H KL showed the highest susceptibility to CotA oxidation when compared to the other hardwood KLs and the softwood KLs. Therefore, this could be a viable method to produce sustainable resins and adhesives. The experimental process involved the reaction of ABTS Diammonium(cas: 30931-67-0SDS of cas: 30931-67-0)
ABTS Diammonium(cas: 30931-67-0) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine. The synthesis of the insect repellent N,N-diethyl-m-toluamide (DEET) incorporates diethylamine while that of the synthetic fibre Kevlar requires aromatic amines.SDS of cas: 30931-67-0
