Title: Isolation,screening and identification of the strain T-8 with high lignin-degrading activity
Abstract: In order to obtain the strain with lignin-degrading capability,79 spore-forming bacterial strains were isolated and screened from specimen collected from the vegetable field,animal manure and silage feed.Total 20 strains with lignin-degrading capability were obtained through the primary screening.Among them,a strain named T-8 was found with higher activity of degrading lignin than other strains via the secondary screening,and the activity of lignin peroxidase was 626.67 U/L.The morphology characteristics,physiological and biochemical characteristics and 16S rDNA sequence of strain T-8 were further studied.It was finally identified as a Bacillus amyloliquefaciens.The similarity of the 16S rDNA sequences between strain T-8 and the other strains of B.amyloliquefaciens was up to 99.91%.
