摘　　要：为探究小球藻在普通环境和模拟微重力环境下对苯酚耐受性能的变化幅度以及驯化培养对小球藻耐酚及降酚能力的影响,从而明确在微重力环境下利用含酚废水大规模培养小球藻的可行性,比较了小球藻在普通环境和模拟微重力环境下的耐酚与降酚能力,并对其进行了驯化培养。结果表明,普通环境下小球藻最大苯酚耐受浓度为600mg·L-1,而在模拟微重力环境下的最大苯酚耐受浓度提高到700mg·L^(-1),且苯酚完全降解所需时间也明显缩短。通过驯化培养得到的小球藻耐酚性能提高,驯化后的小球藻在普通环境下最大苯酚耐受浓度为800mg·L^(-1),在模拟微重力环境下最大苯酚耐受浓度达1 000mg·L^(-1),同时小球藻在模拟微重力环境下降酚能力也显著提高。In order to make clear the feasibility wastewater under microgravity condition,the varia of cultivation of Chlorella sp. on a large scale using phenolic tion range of phenol tolerance of Chlorella sp. as well as the potential in improving the phenol-tolerant and phenol-degrading abilities by domestication culture under general condition and simulated microgravity condition were investigated. The results showed that, the maximum phenol tolerance concentration was 600 mg·L^-1 under general condition,while the maximum phenol tolerance concen- tration increased to 700 mg·L^-1 under simulated microgravity condition,and the complete degradation time of phenol shortened obviously. The phenol-tolerant ability of Chlorella sp. improved by domestication culture. The maximum phenol tolerance concentration of Chlorella sp. was 800 mg·L^-1 under general condition,while the maximum phenol tolerance concentration reached up to 1 000 mg·L^-1 under simulated microgravity condition. Meanwhile,the phenol-degrading ability of Chlorella sp. improved significantly under simulated microgravity condition.
