Dynamics of genetically modified Lactococcus lactis in simulated natural environments and impacts on microbial communities

The survival, impacts on microbiota and gene transfer ability of genetically modified (GM) Lactococcus lactis containing ermAM gene in soil and water environments were investigated. After inoculation of GM L. lactis into environments, its DNA remained longer, and the microbial community was changed. No transfer of chromosomal ermAM was observed.
