| 摘 要： | 利用低功率的X光机,在3.08到18.48戈瑞(Gy)范围内对污染生鲜肉的微生物进行辐照,通过微生物存活率与辐照剂量的相关性分析,得出在此辐照条件下的D10值,并探讨对X射线辐照的敏感性。结果表明:环境污染菌大肠杆菌、蜡状芽孢杆菌及其芽孢的D10值分别为5.41、5.00和23.81 Gy,致病菌金黄色葡萄球菌和单核增生李斯特菌的D10值分别为5.35和6.45 Gy,腐败菌荧光假单胞菌、铜绿假单胞菌及青霉孢子的D10值分别为3.62、4.39和16.39 Gy。供试菌株中蜡状芽孢杆菌芽孢和青霉孢子对辐照的抗性较强,荧光假单胞菌和铜绿假单胞菌对辐照较为敏感。研究亮点:利用低功率的X光机,在Gy剂量范围内对污染生鲜肉的微生物进行辐照,对其杀菌效果进行一定地探索,得到实验中各供试菌株的辐照杀菌致死剂量,获得低功率低剂量X射线仍可对微生物产生一定杀菌效果的初步结论。

| Abstract: | Low power X-ray irradiator was used to irradiate the microorganisms in contaminated fresh beef from 3.08 to 18.48 Gy.D10 values were gained by correlation analysis of microbial survival rate and irradiation dose in this condition.The radiation sensitivity of them was also discussed.The results showed that: the D10 values for environmental polluted bacteria strains of Escherichia coil,Bacillus cereus and its spores were5.41,5.00 and 23.81 Gy respectively.The D10 values for pathogenic bacteria strains of Stap... |
