【摘要】 在实验室条件下,以Zarrouk培养液培养微小色球藻(Chroococcus minutus),探讨温度对微小色球藻生长的影响,并对微小色球藻的营养组成进行了分析。结果表明:在30μE/M2.S~45μE/M2.S光照强度范围内,微小色球藻的最适生长温度范围为30℃~38℃。对微小色球藻的营养组成分析表明,该藻具有高蛋白,低脂肪,脂肪酸组成简单的特点。其粗蛋白含量为61.82%,粗脂含量仅为0.99%,饱和脂肪酸主要为C16:0和C20:0分别占44.88%和11.47%,不饱和脂肪酸主要为18:2n6(占16.01%)。干物质中总氨基酸含量为564.09 mg/g,其中7种必需氨基酸占总量的37.65%,其营养组成与螺旋藻相似。更多还原

【Abstract】 The microalga Chroococcus minutus was cultured in laboratory with Zarrouk medium and the effect of temperature on the growth of Chroococcus minutus was studied.The results indicated that the optimum temperature for Chroococcus minutus growth is between 30 ℃-38 ℃ when a light intensity of 30 μE/M2/S-45 μE/M2/S applied.The nutrition assays showed that this alga has the characters of high protein content(61.82%),low lipid content(0.99%),simple fatty acid composition.The main parts of saturated fatty acid are palmitate(44.88%) and arachidic acid(11.47%).The most unsaturated fatty acid is 18:2n6(16.01%).The amino acid content of the algae is 564.09 mg/g.更多还原
