六种鱼腥藻在大量培养中的生产率和适应性与营养成分比较

COMPARISION OF PRODUCTIVITIES AND ADAPTABILITIES OF SIX STRAINS OF ANABAENA IN MASS CULTURE AND THEIR NUTRITIONAL COMPOSITION

  • 摘要: 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/m2/d以上或接近10g/m2/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。

     

    Abstract: In 1987 and 1988 we compared six strains of Anabaena in outdoor mass culture. The results showed that Anabaena sp. HB1042 and Anabaena sp. HB1105 have capabilities of stable production in the area around the middle and lower reachs of the Yangtze River, from the last tendays of May to the middle ten-days of September (123 days). The average effective growing days of HB1042 and HB1105 were 114 and 100, respectively. Average effective growing days of Anabaena variabilis HB1058, A. azotica HB686 and A. sphearica HB1017 were 73, 58, and 71 respectively. Adaptability of A. oryzae HB13 was relatively poor. Productivities of six strains of Anabaena were relatively high in the last ten-days of May, the first ten-days of June and July and the middle ten-days of August and Septeml er. Average biomass productivities of five strains of Anabaena (except HB13) were 10g (d. wt.)/m-2d-1. or near 10g(d. wt.)/m-2d-1.The six strains of Anabaena expressed their highest productivities in different periods. For this reason, the authors suggest that we can select different strains of Anabaena to obtain the maximum productivities according to seasonal conditions. Nutritional analysis showed that protein ontent of Anabaena spp. is 40% amino acid composition is rational and essential amino acids are in accordance with the standard of FAO/WHO.
