乳酸钠对铜绿假单胞菌生长的影响
Effect of Sodium Lactate on the Growth of Pseudomonas aeruginosa
摘要
Abstract
Nutrient broth media containing different concentrations of sodium lactate （0,0.2, 0.5, 1.0, 1.5 g/100 mE and 2.0 g/100 mL; consequent pH 4.0 -- 6.2） were used to culture Pseudomonas aeruginosa constantly at 25 ℃ to examine the inhibitory effect of sodium lactate on bacterial growth. In the proper pH range, sodium lactate showed outstanding antibacterial activity. At a medium pH level lower than the critical inhibitory pH, the antibacterial effect of sodium lactate was directly proportional to the corresponding concentration. At a medium pH of 4.8, sodium lactate exhibited the highest antibacterial activity at 2.0 g/100 mL, followed by 1.0 g/100 mL; the antibacterial activity was the weakest at 0.5 g/100 mL. At a constant sodium lactate concentration, the antibacterial activity was inversely proportional to medium pH.关键词
