A1 was a polysaccharide obtained from the water extracts of the biomass fermentation, and the sugar composition we try to use RP-HPLC and GC-MS analysis, the related data were shown in the attachment files, however the exact composion of the A1 should conduct more work in the future, and the ratio of the sugar in it and the content of each of the sugar should calculated using the each sugar standard. If there are some suggestions and interested about our research, please don't hesitate email:dyt0623xiang@126.com.
