摘要 | 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ca2+,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。 |
Abstract | The 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 % - I 2 % , the cells almost not increase if over 12 % and even decrease slightly. Different accumulations of inorganic ions present in Dunaliella salina cells cultured in various mediums. |
