Abstract
食用性高蛋白質螺旋藻Spirulina platensis，爲一絕對光自營性生物，除了照度因素外，溫度、接種濃度與培養方式對其生長都有重要的影響。劇烈的攪拌會減弱藻體對高溫及強光的耐性而使生長速率變慢。太過稀薄的藻體則在40℃及強光下生長時會迅速進入衰滅期；然而，提高溫度至40°及45℃時可使較高濃度的藻體得到較大的生長速率與較小的飽和光量。Edible blue-green alga, Spirulina platensis, rich in protein and carotenoids, is an obligate photo-autotroph. Not only light intensity, but also temperature, inoculum size and cultivating type affect the growth of this alga. Violent agitation would decrease the resistance of high temperature and strong illumination, then slow down the growth rate. Too diluted inoculant and strong illumination at 40℃ would quickly make the algal growth approaching to decline phase. However, the maximum algal growth rate and lesser saturation constant of light intensity could be obtained with dense inoculant and increasing the cultivation temperature to 40° and 45℃.
