选用粗沙、细沙和PA6三种固体材料作为培养基质,以BG110为培养液,研究了不同浓度的阿拉伯胶、海藻酸钠和果胶对发菜细胞生物量的影响情况。实验结果表明,添加多糖有利于发菜细胞的生长,其中以细沙为固培基质,在培养液中添加0.3%的果胶,发菜细胞生物量最大,生长速率最快。

The Nostoc flagelliforme cell is cultivated on three solid bed-materials,which are coarse sand,fine sand and PA6,added BG110,then the effects of different concentrations of gum arabic,sodium alginate and pectin on Nostoc flagelliforme cell biomass was investigated.The results indicated that adding polysaccharides were all conducive to the growth of Nostoc flagelliforme cell and that the Nostoc flagelliforme cell that uses fine sand as solid interface with 0.3% pectin in BG110 has the fastest growth rate and the most biomass.
