Ninety-four Gram-positive, catalase-negative bacteria, isolated from pork and chicken that had been packed in modified atmospheres and irradiated to 1.75 and 2.5 kGy respectively, were studied. The majority of the strains were Lactobacillus saké. Numerical taxonomy, with the group average clustering strategy, revealed the existence of six clusters at the 85% similarity level. The largest, Cluster 1, contained 78 (83%) of the test strains along with three Lact. sak'e strains. Cluster 2 contained three test strains and the type strains of Carnobacterium piscicola and Carn. divergens. Cluster 3 contained two chicken strains and Lact. curvatus. Cluster 4 contained a pork strain and Leuconostoc dextranicum. Clusters 5 and 6 contained four pork and two chicken strains respectively and no type strains. Four test strains remained unclustered as did the other reference strains included in the study.
对从分别采用气调包装并辐照至1.75千戈瑞和2.5千戈瑞的猪肉和鸡肉中分离出的94株革兰氏阳性、过氧化氢酶阴性细菌进行了研究。大多数菌株为清酒乳杆菌。采用类平均聚类策略的数值分类法显示，在85%相似性水平上存在6个聚类。最大的聚类1包含78株（83%）测试菌株以及3株清酒乳杆菌菌株。聚类2包含3株测试菌株以及嗜鱼肉杆菌和差异肉杆菌的模式菌株。聚类3包含2株鸡肉菌株和弯曲乳杆菌。聚类4包含1株猪肉菌株和右旋明串珠菌。聚类5和6分别包含4株猪肉菌株和2株鸡肉菌株，且均无模式菌株。4株测试菌株以及研究中纳入的其他参考菌株仍未聚类。
