摘要

"Bacterial strain, plasmu00ecdio, preparation process of a bacterial strain and exopolissacaru00ecdeo bacterial and nucleic acid.This invention relates to a bacterial strain having lost the character fitopatogu00eanico by inactivation of at least one virulence gene, and retained the ability to reproduce exopolissacaru00edDeo.
