适合于咸宁基地生产的螺旋藻品系的选育研究

According to the natural conditions of the Xianning production base in Huhei Province and the demand for mass production,a good strain of Spirulina (Sp)NS-90020 was selected.Besides its fast growth rate, the strain can grow normally within a wide temperature range (10～40℃). Its filterable effeciency, and the contents of protein and polyunsaturated fatty acid are 94.95%,63.37%d.w. and 2.99%d.w., respectively.These characteristics have been proved to be stable in mass production for more than three years. The strain can be cultured continuously in the whole year, and its average protein content is stably above 60%d.w..
