abstract：:Screening of derivatives of Rhizobium etli KIM5s randomly mutagenized with mTn5SSgusA30 resulted in the identification of strain KIM-G1. Its rough colony appearance, flocculation in liquid culture, and Ndv(-) Fix(-) phenotype were indicative of a lipopolysaccharide (LPS) defect. Electrophoretic analysis of cell-associ...
