不同培养基对杜氏藻（DunaliellaSalina）生长和无机离子含量的影响

Effect of various mediums on the growth and in organic ions accumulation of Dunaliella Salina

培养在Ｊｏｈｎｓｏｎ培养液、Ｊｏｈｎｓｏｎ＋０．３％ＮａＣｌ培养液、海水和卤水中的杜氏藻，其生长速度有区别，在Ｊｏｈｎｓｏｎ＋０．３％ＮａＣｌ培养液中生长较好，Ｊｏｈｎｓｏｎ培养液和卤水次之，海水中生长较差。杜氏藻生沃的盐度范围为０～１２％，当培养基中ＮａＣｌ浓度超过１２％时，细胞数几乎不增加，甚至略有降低。在不同培养基中藻细胞Ｈ￣＋含量较稳定，而积累ｃａ￣（２＋），在Ｊｏｈｎｓｏｎ＋０．３％ＮａＣｌ培养液中，杜氏藻细胞Ｎａ￣＋含量增加；而在含高浓度Ｎａ￣＋的海水和卤水中杜氏藻细胞中Ｎａ￣＋的含量低于培养液。

he change of growth rate and inorganic ions accumulation of Dunaliella salina cultured in various mediums were studied.For the growth of Dunaliella salina,it has been shown that Johnson solution containing 0.3%NaCl gives the best result,Johnson solution and brine come next,sea water gives worse result.The concentration range of NaCl for the growth of this algae is 0%～12%, the cells almost not incrcase if over 12%and even decrcase slightly. Different accumulations of inorganic ions present in Dunaliella salina cells cultured in various mediums.
