发菜（Nostocflagelliforme）培养条件的研究

Studies on the Cultivation of Nostoc flagelliforme

采用生物传感仪测定法和DNS法，对加入发菜多糖和发菜细胞培养发酵液的葡萄糖溶液进行了浓度测定，研究了多糖和细胞培养液对葡萄糖浓度测定的影响作用。

The effects of nosoflan and Nostoc flagelliforme cell cultures on the determination of glucose concentration were investigated by applying biological sensor and3,5-dinitrosalicylic acid method ( DNS ) .

以藻体长度增加作为量化指标，以自溶和解体作为质量指标，研究了在不同营养培养基、pH值、光照及初始接种长度条件下对发菜生长的影响。

The effects of different nutritional medium , pH value , light illumination and the length of inoculated thalli on growth of Nostoc flagelliforme have been studied with length increase as quantitative criterion and with autolysis and disintegration as qualitative criterion .

实验范围内沙粒直径＜0.44mm、光照强度为20～45μmol／m／s、添加硝酸钠为氮源有利于发菜细胞在沙粒上生长。

The sand of the diameter littler than 0.44 mm , the illumination intensity of 20 & 45 μ mol / m / s and adding sodium nitrate as nitrogen source could promote the growth of cells cultured on the sand .

结果表明：发菜的生长与栽培时间尺度有一定的关系，培养初期（1周内）发菜的比生长速率较快，日生长为3.5%，10d内发菜净增长了42%，但培养后期发菜生长势头减弱。

The results showed that the specific growth rate ( SGR ) of N. flagelliform was culture-time dependent , that 42 % net increase in dry weight was obtained during the first 10 days cultivation and the maximal daily SGR was 3.5 % .
