| Abstract | The streptococcal plasmid pAMβ_1 (erythromycin resistance)was transferred via conjugation from Streptococcus faecalis DS 5 to Lactobacillus casei YIT 9018 by a filter mating method. The transfer frequency depended greatly on the type, pore size and side(front or back) of membrane filter. Water passing through a membrane under reduced pressure induced very tight contact between the cells, increased the transconjugation frequency about 1.3 to 37-fold when Millipore membrane filter (0.45.mu.m, front side up) was used. | ||
