          摘要:

          以中慢生根瘤菌S-15和類芽胞桿菌S-17作為供試菌株,采用細胞破碎、NH4OAc浸提、H2O2溶液消煮及不作任何前處理等4種方法,利用火焰光度計檢測解鉀菌發酵液中K+含量,并計算解鉀菌在培養基中的解鉀效率。結果表明,配制的3種鉀系列標準溶液所繪制的鉀標準曲線較為接近,R2分別高達0.994 4、0.999 7、0.999 8。采用H2O2消煮后所測得的K+濃度最高,2株解鉀菌的解鉀效率分別達到101.1%、125.1%,與其他處理組之間有顯著性差異。用H2O2溶液處理所得到的解鉀率更能真實反映解鉀菌的解鉀作用。

          Abstract:

          Using Mesorhizobium sp.S-15 and Paenibacillus sp.S-17 as experimental strains.After cell disruption,NH4OAc extraction,H2O2 solution digestion or without any pre-treatment,K+ content in the fermentation broth of potassium solubilizing bacteria was determined with flame photometer.The efficiency of K solubilizing by potassium solubilizing bacteria in the culture medium was calculated.The results showed that the standard curves of the three kinds of K series of standard solutions were similar with the R2 values of 0.994 4,0.999 7 and 0.999 8,respectively.After digested by H2O2 solution,concentration of K+ was detected.The efficiency of two strains was 101.1% and 125.1%,significantly higher than that of other groups.The efficiency of potassium solubilizing detected after H2O2 digestion well reflected potassium solubilization of bacteria.
