连续两年对鱼腥藻的六个品系进行了大量培养比较研究,在长江中下游气候条件下,HB1042和HB1105具有稳定的生产性能,5月下旬至九月中旬123d内,平均有效生长分别为114和100d;其次是HB1058,HB686和HB1017,平均有效生长天分别为73,58和71d;HB13适应性较差。生物量生产率在5月下旬、6月中旬至9月中旬较高,除HB13外,平均都在10g干重/m~2/d以上或接近10g/m~2/d。在不同的季节它们表现出了各自的最高生物量生产率。据此,提出了逐月逐旬采取藻种搭配生产,以获得最高生物量生产率的配合关系。营养成分分析表明它们的蛋白质含量在40％左右;氨基酸组成合理,除某些种类的含硫氨基酸略低外,都符合FAO/WHO的标准。
For two consecutive years, six strains of Anabaena were extensively cultured and compared. Under the climatic conditions in the middle and lower reaches of the Yangtze River, HB1042 and HB1105 had stable production performance. Within the 123 days from late May to mid September, the average effective growth rates of HB1042 and HB1105 were 114 and 100d respectively; followed by HB1058, HB686 and HB1017, with the average effective growth days of 73, 58 and 71d, respectively; and the poor adaptability of HB13. Biomass productivity was higher in late May and mid-June to mid-September, with an average of 10g dry weight / m ~ 2 / d or nearly 10g / m ~ 2 / d, except HB13. They showed their highest biomass productivity in different seasons. According to this, we propose to adopt a monthly month-by-month to take with the algae species production, in order to obtain the highest biomass productivity with the relationship. Nutritional analysis shows that their protein content is about 40%; amino acid composition is reasonable, with the exception of some slightly lower sulfur-containing amino acids, are in line with FAO / WHO standards.
