Abstract

During a two year screening period, approximately 200 phages active against lactic streptococci have been isolated in a cheese factory from raw milk, cheese whey and starter culture using an indicator set of 24 strains of Streptococcus lactis, 17 strains of S. cremoris and 16 strains of S. lactis subsp. diacetylactis. Electron microscopy of these phages suggests the existence of at least 14 distinct morphological types. The ultrastructural and host range properties of 14 typical phage types are described and discussed.

N群(乳酸)链球菌噬菌体的分离及超微结构研究
在为期两年的筛选期间,利用24株乳酸链球菌、17株乳糜链球菌和16株乳酸链球菌亚种的指标集,从一家奶酪工厂的原料奶、奶酪乳清和发酵剂中分离出了大约200株抗乳酸链球菌的噬菌体。diacetylactis。这些噬菌体的电子显微镜显示存在至少14种不同的形态类型。描述和讨论了14种典型噬菌体类型的超微结构和宿主范围特性。
