摘要: 本文研究了氮盐对螺旋藻生长及胞外多糖积累的影响,发现低氮培养条件对螺旋藻生物量积累影响不太明显,但却有利于螺旋藻胞外多糖的积累。氮源不仅是决定螺旋藻生物量的积累的主要因素,也是螺旋藻胞外多糖的限制因素。

Abstract: The effect of Nitrogen on the accumulation of bio-mass and exopolysacchride of Spirulina Platensis was studied,and it is confirmed that low Nitrogen have a little influences on the biomass but promote the accumulation of Spirulina Platensisexopolysacchride. The Nitrogen not only influence the the biomass of Spirulina Platensis but also its content of exopolysacchride.

Key words: Spirulina Platensis, Nitrogen, Exopolysacchride
