From: A Novel Biocontainment Strategy Makes Bacterial Growth and Survival Dependent on Phosphite

Spot assay to assess growth of RN1008 and related strains on various types of solid media. MOPS-SE were prepared from two types of humic soils to create MOPS-SE[A] and MOPS-SE[B]. Pictures were taken at 48 h after incubation. Strains used (left to right): MG1655, MG1655 harboring Ptac4071-ptxD/pTWV, MT2012, RN1007, and RN1008.
