Effects of Gas Vesicle Collapse under Pressure on Growth and Photosynthesis of Three Planktonic Cyanobacteria Strains

  • 摘要: 采用批量培养方式,研究了伪空胞的破裂对3种典型水华蓝藻——铜绿微囊藻(Microcystis aeruginosa)、螺旋鱼腥藻(Anabaena spiroides)和孟氏浮游蓝丝藻(Plankothrix mougeotii)生长的影响,同时分析了伪空胞破裂对3种藻光合作用及细胞形态的影响.结果表明,伪空胞破裂对3种藻的生长影响不同,铜绿微囊藻和孟氏浮游蓝丝藻的细胞生长不受伪空胞破裂的影响,而螺旋鱼腥藻生长初期出现了5 d的延滞期;伪空胞破裂对3种藻光合作用影响较小,其中铜绿微囊藻和螺旋鱼腥藻的光合作用没有受到影响,而孟氏浮游蓝丝藻在饱和光强时最大光合作用速率降低了12.6%.铜绿微囊藻、孟氏浮游蓝丝藻及螺旋鱼腥藻细胞在伪空胞破裂后恢复较快,在3~5 d内又重新生成了大部分的伪空胞.
