摘要：

The conjugative transfer of plasmid RP4 between two strains of Escherichia coli in a sterile marine sediment was enhanced by the presence of glycine betain (frequency increased 20 to 40 times). The conjugation was also faciliatated by the osmoprotection of donor cells. Glycine betaine is a universal osmolyte and has been found in marine sediments at hight concentrationS. So this phenomenon could have epidemiological and sanitary importance by increasing the possibility of dissemination of some plasmids present in enterobacteria in natural mairne deposits Copyright © 1990, Wiley Blackwell.
