摘要
以胶冻样芽孢杆菌菌株(ACCC10012)为出发菌株,经紫外线诱变处理,获得两株胶冻样芽孢杆菌高产菌株UV09K,UV16K,其解K能力较出发菌株分别提高1282.35%,1909.80%。同时通过酸碱和温度处理,获得了一株抗性变异株PHt10K,该菌株能承受pH=4～10,t 50 的不良环境,而且解P解K能力较出发菌株提高35.97%,23.53%。
Two highly productive phosphorus strains, UV09K and UV16K, whose capability of decomposing phosphate rocks increases by 1282.35% and 1909.80% respectively compared with that of the parent strain, were obtained by exposing the parent strain ACCC10012 to ultraviolet. When the two strains were treated with acid, alkali and temperature, a mutation-resistant strain PHt10K was obtained. The new strain can survive under the condition of pH = 4~10 and t < 50℃ and its phosphate-decomposing capacity was 35.98% and 23.53% respectively higher than its parent strains.
