摘要:
植物分泌物和功能微生物的相互作用对于植物－微生物系统净化水质效果扮演着重要的作用.加入3种植物(黄花水龙、凤眼莲、伊乐藻)的分泌物对接种的氮循环微生物和光合细菌进行培养,结果表明:3种水生植物粗分泌物对光合细菌都起到了促进生长的作用,但是对于氮循环微生物却有不同的作用效果:分泌物对氨化菌和反硝化菌生长有促进作用,但是对于亚硝化菌和反硝化菌表现出抑制的作用,而且不同水生植物的分泌物对微生物作用大小也有所差异.这些结果能为今后进行植物－微生物修复体系中选择何种水生植物和接种微生物才能起到最佳的修复效果提供依据.
Abstract:
The interaction between crude exudates of aquatic macrophyte and functional bacteria play an important role to purify water in the plantbacteria integrated systems.The effects of inoculated the crude extrudes of three macrophytes(Jussiaea stipulacea Ohwi,Eichhornia crassipes and Elodea nuttallii) on growth of photosynthetic bacteria,INCB community were studied.Results showed that the crude exudates promoted the growth of photosynthetic bacteria,ammonifying bacteria and denitrifying bacteria,but inhibited the growth of nitrosation,nitrifying bacteria communities.And the different macrophyte produced different effects.The results can provid the basis theory for selecting suitable aquatic macrophyte and functional bacteria to form effective plant-bacteria system to remediate eutrophic water body.
