    摘要： A yellow pigments generation deficient Sphingomonas strain (Sphingomonas sp. ZD001) and application thereof in preparing gellan gum by microbial fermentation are provided. The strain is preserved in China Center for Type Culture Collection (CCTCC) with the address of Wuhan University, Wuhan, 430072, China, the preservation date of the strain is 10 Sep. 2009, and the preservation serial number is CCTCC No: M 209298. The main beneficial effect of the present invention is that the fermented liquor contains no yellow pigments but is milky white, colorless superior gellan gum can be obtained by only depositing polysaccharide with a small quantity of ethanol or isopropanol, so that the post purification and de-coloration techniques of gellan gum production can be simplified, the yield can be enhanced, and the production cost can be reduced.

    摘要翻译： 提供黄色色素代谢缺陷型鞘氨醇单胞菌（Sphingomonas sp。ZD001）及其通过微生物发酵制备吉兰糖胶的应用。 该菌株保藏在中国类型培养物保藏中心（CCTCC），武汉大学地址，武汉，430072，保护期为2009年9月10日，保藏号为CCTCC号：209198 本发明的主要有益效果在于，发酵液不含黄色颜料，但为乳白色，仅通过少量乙醇或异丙醇沉淀多糖即可获得无色的优质结冷胶，因此后期纯化和脱色 可以简化结冷胶生产的成色技术，可以提高产量，降低生产成本。
