Ramie bast is a kind of multipurpose biological material. Selective bio-degradation of ramie bast compounds is an important step to partial utilization of complex polysaccharides. Bacillus subtilis is a kind of dominant species with its ability to degrade ramie bast. In order to understand how polysaccharides were catalyzed and utilized in the metabolism of the bacteria, the proteome of B. subtilis strain 168 was analyzed in the presence of ramie bast as sole carbon source,...
