摘要
培养基中不同的碳源影响冰核细菌的冰核活性、生物量和产胶率,麦芽糖、山梨醇、蔗糖等均可做为促进冰核细菌生长碳源,麦芽糖作为碳源加入发酵培养基中生物活性和生物量均较高,同时产胶率低于葡萄糖和蔗糖十倍左右。麦芽汁代替麦芽糖可以降低产胶率,但效果不如麦芽糖。在培养基中加入0.1ml/100ml乳酸可以有效地抑制黄原胶的产生,而对冰核活性和生物量影响不大。
Different carbon source in medium affected the cell growth, the ice nucleation activity and the gum ratio. Maltose,sorbitol and sucrose promoted the cell growth. Maltose as the carbon source, the gum ratio was less than such about ten timesin other carbons source as glucose and sucrose. Wort as the substitute of maltose can depress the gum ratio, but the effect not asgood as maltose. Addition of 0.1% lactate in the medium can inhibit the gum production effectively, and not too affected the icenucleation activity and the biomass.
