摘要黄原胶是由野油菜黄单胞菌产生的一种杂多糖。研究了一株野油菜黄原胶菌株在不同碳源条件下发酵产黄原胶的效果。碳源对多糖产量有影响。在合成培养基中黄原胶的产量为15.654 g/l。研究了在25 °C和40°C之间的各种温度下黄原胶的生产。 在25-30 °C之间生长和产量最高。 黄原胶产量在pH 7.0-7.5时最大。
Abstract Xanthan is an heteropolysaccharide produced by Xanthomonascampestris. Xanthan gum fermentation by a local isolate of X. campestris using different carbon sources was studied. The production of polysaccharide was influenced by the carbon source used. The production of the xanthan was 15.654 g/l with synthetic medium. Production of xanthan at various temperatures ranging between 25 °C and 40 °C was studied. The growth and production was maximum between 25–30 °C. Xanthan production was maximum at pH 7.0–7.5.
