ABSTRACT This study reports on the identification and characterization of a novel abortive infection system, AbiU, from Lactococcus lactis. AbiU confers resistance to phages from the three main industrially relevant lactococcal phage species: c2, 936, and P335. The presence of AbiU reduced the efficiency of plaquing against specific phage from each species as follows: 3.7 × 10−1, 1.0 × 10−2, and 1.0 × 10−1, respectively. abiU involves two open reading frames,abiU1 (1,772 bp) and abiU2 (1,019 bp). Evidence indicates that AbiU1 is responsible for phage resistance and that AbiU2 may downregulate phage resistance against 936 and P335 type phages but not c2 type phage. AbiU appeared to delay transcription of both phage 712 and c2, with the effect being more marked on phage c2.

The genome of Lactococcus lactis subsp. lactis bv. diacetylactis SD96, a strain used for cheese production, is presented. SD96 is refractory to phage attack, which is a desired property for starter bacteria. Its 10 plasmids provide industrially important traits, such as lactose and citrate metabolism, proteolytic activity, and phage resistance.
