摘要

摘要: 为探究细菌Chryseobaterium sp.的溶藻能力及方式,通过扫描电镜观察细菌Chryseobaterium sp.对藻Anabaena flosaquae的作用效果,进一步通过分离菌体和菌上清液的方法探讨其溶藻的作用机制。结果表明:细菌Chryseobaterium sp.具有很强的溶藻能力,其主要通过分泌溶藻活性物质进行间接溶藻。胶囊制备的优化条件为:SA、CaCl₂、EC和柠檬酸质量分数分别为3%、3%、3%和2%,CaCO₃与SA的质量分数比为4/5,交联时间为30 min,溶藻物质质量分数为16%,该条件下所制胶囊缓慢释放溶藻物质,具有长效的溶藻能力。揭示了细菌Chryseobaterium sp.主要通过分泌溶藻活性物质进行间接溶藻,所制胶囊具有较强的溶藻能力,为细菌Chryseobaterium sp.溶藻机理和生物控藻技术的研究提供了理论依据。
