Outline of Final Research Achievements |
To establish of standardized model ecosystem for environmental assessment of alien species, microcosm test was conducted. Several species of bacteria as genetically engineered microorganisms (GEMs) were assessed using experimental microcosm system of prey-predator interaction test, gnotobiotic microcosm test and naturally derived microcosm test. As results, allGEMs didn’t increase their individual number in microcosm, and finally be removed from the ecosystem site under biological interaction with indigenous microbiota.
