摘要
研究了温度和光强对极大螺旋藻438多糖和SOD酶活力的影响。结果显示:对极大螺旋藻生长不利的温度、光照条件,会促进螺旋藻胞外多糖的分泌和提高超氧化物歧化酶(SOD)的活性,即高温和弱光更利于胞外多糖的积累,低温和强光显著提高SOD酶活力,而胞内多糖积累的条件与螺旋藻的最适生长条件(30℃,5000 lux)一致。此研究结果为通过优化培养条件调控活性物质提供了理论依据。
The effects of temperature and illumination on polysaccharides and SOD activity in Spirulina Maxima were studied. The results showed that： illumination and temperature that unsuitable for the growth of Spirulina Maxima would raise extracellular polysaccharide content and SOD activity. In particular, high temperature and feeble illumination were favorable to the excreting of extracellular polysaccharide. SOD activity was increased notably under low temperature and strong light. The optimum temperature and light for excreting of intracellular polysaccharides were consistent with optimum condition for the growth of Spirulina Maxima. The results provided the theory and practical parameters of scale-up exploitation in the functional food and pharmacy.
