Plasmid distribution and evidence for a proteinase plasmid in Streptococcus lactis C2-1.

چکیده
Five plasmids, distinguishable by their molecular weights (10(6), 2 x 10(6), 5 x 10(6), 10(7), 3 x 10(7), respectively) were isolated from Streptococcus lactis C2. A spontaneous proteinase-negative derivative of this strain lacked the 10(7) plasmid.

Transductional evidence for plasmid linkage of lactose metabolism in streptococcus lactis C2.
A lactose-negative (Lac-), proteinase-negative (Prt-) mutant, designated C145 was isolated from Streptococcus lactis C2 after treatment with nitrosoguanidine and ultraviolet irradiation. The mutant appeared to be cured of the prophage(s) present in S. lactis C2 based on non-inducibility by ultraviolet irradiation or mitomycin C. When cleared lysate material from C145 was subjected, to cesium ch...
متن کاملConjugative 40-megadalton plasmid in Streptococcus lactis subsp. diacetylactis DRC3 is associated with resistance to nisin and bacteriophage.
Streptococcus lactis subsp. diacetylactis DRC3 was examined for plasmid DNA and found to contain a previously unreported plasmid of 40 X 10(6) daltons. This plasmid, designated pNP40, was conjugally transferred to a plasmid-cured derivative of S. lactis C2. Transconjugants containing pNP40 acquired resistance to nisin produced by strains of S. lactis and to commercially available nisin when ass...
متن کاملPlasmids in Streptococcus lactis: evidence that lactose metabolism and proteinase activity are plasmid linked.
Populations of lactose positive (Lac+) and proteinase positive (Prt+) cells from Streptococcus lactis M18, C10, and ML3 grown at 39 degrees C gave rise to increasing proportions of Lac- Prt- clones. The deficiencies did not appear until after a number of generations at the elevated temperature, and the rate depended on the strain.Lac- Prt+ and Lac+ Prt- mutants were isolated after treatment wit...
متن کاملPlasmid transfer via transduction from Streptococcus thermophilus to Lactococcus lactis.
Using Streptococcus thermophilus phages, plasmid transduction in Lactococcus lactis was demonstrated. The transduction frequencies were 4 orders of magnitude lower in L. lactis than in S. thermophilus. These results are the first evidence that there is phage-mediated direct transfer of DNA from S. thermophilus to L. lactis. The implications of these results for phage evolution are discussed.
متن کاملCloning in Streptococcus lactis of plasmid-mediated UV resistance and effect on prophage stability.
Plasmid pIL7 (33 kilobases) from Streptococcus lactis enhances UV resistance and prophage stability. A 5.4-kilobase pIL7 fragment carrying genes coding for both characters was cloned into S. lactis, using plasmid pHV1301 as the cloning vector. The recombinant plasmid was subsequently transferred to three other S. lactis strains by transformation or protoplast fusion. Cloned genes were expressed...
