鲍鱼壳煅烧物抗菌活性初步研究

研究鲍鱼壳煅烧物对几种常见致病菌的体外抗菌活性。采用滤纸片法和牛津杯双层琼脂扩散法测试不同温度段鲍鱼壳煅烧物对受试菌的抑制作用,并用琼脂梯度稀释法确定最小抑菌浓度(MIC)。结果表明:当煅烧温度段≥800℃,鲍鱼壳煅烧物对几种常见致病菌均有较强的抑制作用,尤其对金黄色葡萄球菌和铜绿假单鲍菌具有显著的抑制作用(p<0.05),MIC分别为1 mg/m L和0.5 mg/m L;并且在一定温度范围内,其对受试菌的抑制能力均随煅烧温度的升高而显著增加,在1100℃煅烧温度上抗菌效果最好。 

The preliminary study on antibacterial activity of abalone shell calcinate

The antibacterial activities of abalone shell calcinate against the common pathogenic bacteria were studied.Both of filter paper and Oxford cup double agar diffusion methods were used to detect the constrain on the specific bacteria of different temperature rangesbalone shell calcinate,while the minimal inhibitory concentration( MIC) was determined by agar gradient dilution method.The results showed that abalone shell calcinate inhibited strongly against those common pathogenic bacteria in the calcining temperature ranges ≥ 800 ℃,especially significantly for Staphylococcus aureus and Pseudomonas aeruginosa( p < 0.05). MIC was 1 mg / m L and0.5 mg / m L. And within a certain temperature range,the inhibition ability increased with the calcining temperatures,with the optimal antimicrobial calcining temperature at 1100 ℃.
