摘要
目的:探讨pH和钙离子(Ca^(2+))对分别来自窄食单胞菌、气单胞菌、肠杆菌和马氏杆菌四个属的四株微生物的影响。方法:分别在不同pH和不同Ca^(2+)浓度条件下培养微生物,比较不同培养条件下微生物培养物的比浊度(OD_(600))。结果:除窄食单胞菌外,其余三个菌株都偏爱碱性的培养条件;150 mg/L浓度的Ca^(2+)对窄食单胞菌和气单胞菌具有显著的抑制效果,对肠杆菌和马氏杆菌属的菌株无显著影响。结论:pH和Ca^(2+)对潜在病原微生物的直接影响依菌种不同而呈现差异。
Objective:To investigate the effects of pH and calcium ions(Ca^(2+))on four strains of microorganisms from four genera of Stenotrophomonas,Aeromonas,Enterobacter and Macellibacteroides,respectively.Methods:The microorganisms were cultured at different pH and Ca^(2+)concentrations,and the specific turbidity(OD_(600))of the microbial cultures were compared under different culture conditions.Results:All the three strains,except Stenotrophomonas,preferred alkaline culture conditions;Ca^(2+)at 150 mg/L concentration had significant inhibitory effects on Stenotrophomonas and Aeromonas,but had no significant effects on the strains of the Enterobacter and Macellibacteroides genus.Conclusion:The direct effects of pH and Ca^(2+)on potential pathogenic microorganisms showed differences depending on the strains.
