plasmids which assigns subjects - ufoelsomhed to bacteria containing such plasmids, and the use of such plasmids and cultures within foedevareindustrien
The invention relates to a plasmid, other than a plasmid in a naturally occurring host/plasmid combination, carrying one or more genes which confer phage insensitivity upon Streptococcus lactis or Streptococcus lactis subsp. diacetylactis as well as Streptococcus cremoris bacteria, the capability of conferring phage insensitivity not being destroyed by temperatures of up to 40 DEG C. Two such plasmids are characterized in terms of their sensitivity to restriction endonucleases. The invention further relates to DNA from such a plasmid which encodes phage insensitivity. The invention also provides bacterial hosts containing a plasmid as above and food starter cultures containing such bacterial hosts.
