| 摘 要： | 利用藻类批量培养试验研究了不同初始pH和不同固定pH对三种淡水蓝藻和三种淡水绿藻生长的影响。结果表明:藻类对水体pH有较强的缓冲能力,可以通过自身增殖活动改变水体的pH,因而不同初始pH对藻类生长的影响不明显,但加了pH缓冲剂固定初始pH后,藻类的生长反应很明显,适宜的pH范围各不相同,铜绿微囊藻(Microcystis aeruginosa)、水华鱼腥藻(Anabaena flos-aquae)、浮游颤藻(Oscillatoria planctonica)适宜的pH分别9.0、8.0～9.0和7.0～8.0,斜生栅藻(Scendesmus obliquus)、绿球藻(Chlorococcum sp).、雷氏衣藻(Chlamydomonas reinhardtii)适宜的pH分别为9.0～10.0、7.0～8.0和7.0。蓝藻适宜的pH并不都比绿藻的高。 |

| Abstract: | Growth of algae at different initial and constant pH values was studied with bulk culture.Initial pH value in BG11 culture medium was adjusted to 6.0,7.0,8.0,9.0 and 10.0 with either 0.5mol/L NaOH or 0.5mol/L HCL.Constant pH values were kept by addition of 20mmol/L bicine.Results showed that different initial pH values had slight effects on growth of algae,because pH values changed to about 10.0 after 4 days of cultivation,but different constant pH had marked effect on growth of algae.Optimal pH values for ... |
