Production, characterization, and prebiotic activity of oligosaccharides from konjac glucomannan by Bacillus amyloliquefaciens WX-1

Konjac glucomannan (KGM) oligosaccharides from KGM is a potentially and valuable prebiotics. A KGM degrading strain was screened and identified as Bacillus amyloliquefaciens WX-1. B. amyloliquefaciens WX-1 was shown to efficiently depolymerize KGM and produce a broad range of small molecule oligosac...
