摘要 Caloglossa leprieurii (Montagne) J. Agardh 是从淡水、河口和海洋地区分离得到的。根据内部离子浓度（K+、Na+ 和 Cl−）和有机溶质甘露醇研究了这些分离株在 0-48 小时时间内对一系列外部盐度的响应。细胞内离子对低盐和高盐处理的反应迅速变化，并在 1 小时内达到稳态条件。在所有盐度下，钠离子似乎都被排除在细胞之外。所有群体中甘露醇的浓度与盐度呈正相关。 8 小时内显示出一些甘露醇在高盐介质中积累，但通常直到 24 小时后才达到新的稳态。在低盐介质中，甘露醇浓度在1小时内显着降低。三个群体之间无机离子和甘露醇变化的程度和速率各不相同。甘露醇作为相容性溶质的相关性及其影响...的潜力
Abstract Caloglossa leprieurii (Montagne) J. Agardh was isolated from a freshwater, an estuarine and a marine locality. The responses of these isolates to a range of external salinity over time periods of 0–48 h was investigated in terms of internal ion concentrations (K+, Na+ and Cl−) and the organic solute mannitol. Changes in intracellular ions in response to hyposaline and hypersaline treatments were rapid with steady state conditions achieved within 1 h. Sodium ions appeared to be excluded from the cells in all salinities. The concentration of mannitol in all populations correlated positively, with salinity. Some mannitol accumulation in hypersaline media was shown within 8 h, but in general a new steady state was not achieved until after 24 h. In hyposaline media mannitol concentration decreased markedly within 1 h. The extent and rate of the change in inorganic ions and mannitol varied between the three populations. The relevance of mannitol as a compatible solute, as well as its potential to effec...
