一株黄单胞菌NYW79及其用途
摘要：
本发明涉及一种黄单胞菌(Xanthomonas sp.)NYW79及其用途。使用NYW79菌株生产无色素黄原胶的步骤包括活化培养、液体种子培养、发酵培养与黄原胶沉淀等步骤。使用NYW79菌株生产黄原胶的产量比诱变出发NY07菌株提高14.9％以上；发酵液的OD值降低77.1％以上，由NYW79菌株生产黄原胶能够从根本上解决黄原胶产品的脱色问题，同时黄原胶多糖产量也非常显著提高。
摘要（英）：

The invention relates to Xanthomonas sp. NYW79 and use thereof. NYW79 strain is used to produce non-pigmented xanthan gum via the following steps such as activation culturing, liquid seed culturing, fermentation culturing and xanthan gum precipitating. The yield of xanthan gum production using the NYW79 strain is higher than 14.9% as high as that by induction of starting NY07 strain; OD value of fermentation broth is decreased by higher than 77.1%, the production of xanthan gum with NYW79 strain can substantially solve the fading problem of xanthan gum products, and xanthan gum polysaccharide yield is significantly increased.
