Dna encoding phage abortive infection protein from lactococcus lactis, and method of use thereof

摘要

DNA encoding phage resistance protein which aborts infection by the phage, designated as AbiE. The DNA which is contained in a Lactococcus lactis deposited as NRRL-B-21443 and described in SEQ ID NO: 1, is incorporated into a bacterium to encode the AbiE and provide phage resistance. Lactococcus and other bacteria encoding the AbiE are useful in industrial fermentations wherein phage are a problem.
