发酵前包被裂殖壶菌微胶囊工艺优化及其对 裂殖壶菌生长和代谢特性的影响Optimization of the preparation process of Schizochytrium sp. microcapsules before fermentation and its effect on the growth and metabolic properties of Schizochytrium sp.

为了探究发酵前微胶囊化对裂殖壶菌生长代谢及二十二碳六烯酸（DHA）生产的影响，采用内源乳化凝胶法制备发酵前裂殖壶菌微胶囊，通过单因素实验和正交实验优化微胶囊制备工艺，并探究了裂殖壶菌在固化核心和液化核心两种微胶囊条件下的生长、代谢特性及耐热性。结果表明：裂殖壶菌微胶囊的最佳制备条件为海藻酸钠质量浓度12 g/L、Span 85添加量2 g/L、水油相体积比1∶ 3、搅拌速度300 r/min，在此条件下微胶囊平均粒径为（420.49±23.12） μm，最适粒径比例为55.74%，得率为73.10%。微胶囊环境下裂殖壶菌呈现聚团生长特征；与游离培养相比，微胶囊培养裂殖壶菌的葡萄糖消耗无显著变化...
