【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。更多还原

【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.更多还原
