摘要
研究了盐泽螺旋藻的形态、生理生化特性和在不同条件下的生长状况,并与其他螺旋藻进行了比较。盐泽螺旋藻、极大螺旋藻和钝顶螺旋藻在蛋白质的含量、氨基酸组分以及可见光吸收光谱等方面差别不大。盐泽螺旋藻的生长速度最快(世代时间为8.4h)。极大螺旋藻、钝顶螺旋藻1926和钝顶螺旋藻2340的世代时间分别为11、11.8和14.8h。盐泽螺旋藻的光合作用和呼吸作用强度亦大于极大螺旋藻和钝顶螺旋藻。此外,这种藻对盐分和温度还具有较宽的适应范围,在形态上也和其他3种螺旋藻有较大之差异。
Morphology, physiology, biochemical composition and growth of Spirulina siibsalsa were studied and compared with those of other Spirulina. There are no apparent differences in protein content, amino acid composition and contents of several pigments among S. subsalsa, S. maxima and S. platensis. The generation time of S. subsaha is 8.4 hours. This growth rate is higher than that of any other species reported in the present paper. The generation times of 5. maxima, S. platensis 1926 and S. platensis 2340 are 11.0, 11.8 and 14.8 hours respectively. S. subsalsa exhibits a wider tolerance of temperature and salinity, and is easily harvested with simple methods. Both rates of photosynthetic oxygen evolution and respiratory oxygen uptake of S. subsalsa are higher than those of S. maxima and S. platensis. The potential of improving the medium is discussed.
