摘　　要：将2株具有植物促生长潜力的锰氧化细菌(manganese oxidizing bacteria,MOB)——微小杆菌属(Exiguobacterium)OS和松鼠葡萄球菌(Staphylococcus sciuri)WLS01分别定殖到漂浮植物大薸根部,通过观察和测定水培14 d前后植物的生长和生理响应、水中锰和氨氮含量、植物对锰的转运的变化来研究MOB定殖对植物的影响。结果表明:定殖OS和WLS01后大薸生物量增长比例分别达到31.29%和25.81%,远高于未定殖组,同时增强了其光合作用。但定殖MOB后的大薸根部出现损伤。Exiguobacterium sp.(OS)and Staphylococcus sciuri(WLS01),which were two strains of manganese oxidizing bacteria(MOB)with plant growth promoting potential,were inoculated in the roots of the floating plant Pistia stratiotes,respectively,the effects of MOB colonization on plants were studied by observing and measuring the growth and physiological response of plants before and after 14 days of water cultivation,changes in manganese and ammonia nitrogen content in water,and changes in manganese transport by plants.The results showed that colonization of OS and WLS01 led to an increase in P.stratiotes biomass by 31.29%and 25.81%,respectively compared to the uncolonized group,and the colonization also improved the plant photosynthesis.But after colonization MOB,damage appeared in the roots of P.stratiotes.
