Abstract

Starter culture lysis by Lactococcus lactis bacteriophages is one of the leading causes of the fermentation failure in dairy industry. In the present work we performed a PCR grouping of lactophages identified in 73 samples of milk whey obtained from industrial facilities located in Russia. From these samples we isolated 10 novel L. lactis bacteriophages associated with the fermentation failure in different regions of the Russian Federation. The genomes of these bacteriophage isolates are closely related and similar to the known c2-like phages (Ceduovirus genus). However, the allelic variants of the receptor recognition proteins found in these genomes were different.

俄罗斯乳业工厂乳酸乳球菌噬菌体的生物多样性、分离和测序

摘要乳酸菌噬菌体裂解发酵剂是乳制品发酵失败的主要原因之一。在目前的工作中，我们对从俄罗斯工业设施获得的73份乳清样品中鉴定的乳清噬菌体进行了PCR分组。从这些样品中，我们分离出10种与俄罗斯联邦不同地区发酵失败相关的新型乳酸乳杆菌噬菌体。这些噬菌体分离物的基因组与已知的c2样噬菌体(ceduvirus属)密切相关且相似。然而，在这些基因组中发现的受体识别蛋白的等位变异是不同的。
