摘    要:从云南石林,建水采取烟草根部土样,按10-4、10-5梯度稀释并涂布平板,在28℃培养条件下,从硅酸盐固体培养基上初步筛选得到77株解钾菌株,具有透明圈的65株.采用液体培养法(火焰分光光度计法)测定其解钾能力作进一步复筛,获得34株具有较高解钾能力的菌株,其有效钾活性为0.4~10.6 mg/L,同时采用高温筛选出一株耐70℃高温,且具有较好解钾能力的菌株K77,经初步鉴定为侧孢芽孢杆菌(Bacillus Lateraporus),该菌解钾活性达到10.6 mg/L.

关 键 词:云烟高端品牌  根际土壤  解钾细菌

Abstract:The method of gradient dilution coating was adopted to isolate high effective potassium bacteria from tobacco rhizosphere soil collected from Shilin city and Jianshui city,Yunnan Province.The results showed that 77 microbial strains was selected from the solid medium with silicate.Among them,65 strains had transparent circle.The rescreening was conducted with atomic absorption spectrophotometer method to mensurate the ability of potassium dissolution,34 microbial strains with effective ability of potassium-...
Keywords:High-end brand tobacco  Rhizosphere soil  Potassium bacteria
