| Research Abstract |
This study aimed at revealing the detail and the generality of nonconjugative, nonviral horizontal gene transfer in colony biofilms of Escherichia coli. We found that this horizontal gene transfer is a novel kind of transformation, that there are several dozens of genes which are involved in this gene transfer in E.coli, and that this gene transfer occurs on the culture on food-based media as well as between E.coli and Bacillus subtilis.
