一种通过发酵条件控制提高黄原胶白度的方法及黄原胶发酵液检测方法
摘要：
本发明公开了一种通过发酵条件控制提高黄原胶白度的方法及黄原胶发酵液检测方法，所述一种通过发酵条件控制提高黄原胶白度的方法，步骤如下：(1)斜面培养、(2)液体发酵培养；所述液体发酵培养，操作如下：取一环斜面菌株接种于NF‑5液体发酵培养基中，该发酵培养基包含如下成分：35g/L蔗糖、0.5‑1g/L酵母粉、0.5‑1g/L酪蛋白胨、0.5‑1g/L尿嘧啶、0.5‑1g/L(NH4)HPO4、1g/L CaCl2、1g/L KH2PO4，培养温度30℃，好氧条件下培养80‑100h。本方法步骤简单，产物提取成本低，产物品质好。
摘要（英）：

The invention discloses a method for improving the whiteness of xanthan gum through fermentation condition control and a method for detecting a xanthan gum fermentation broth. The method for improvingthe whiteness of the xanthan gum through fermentation condition control includes the following steps of firstly, conducting slope culturing; secondly, conducting liquid fermentation culturing, wherein the liquid fermentation culturing includes the substeps of inoculating a ring slope strain in an NF-5 liquid fermentation culture medium and conducting culturing for 80-100 h under the aerobic conditions at the culture temperature of 30 DEG C, and the fermentation culture medium comprises 35 g/L cane sugar, 0.5-1 g/L yeast powder, 0.5-1 g/L casein peptone, 0.5-1 g/L uracil, 0.5-1 g/L (NH4)HPO4,1 g/L CaCl2 and 1 g/L KH2PO4. The method includes simple steps and is low in product extraction cost and good in product quality.
