The studies to work out the most suitable medium for the growth of Clavibacter michiganensis subsp michiganensis was carried out using nonselective (NA, NGY, YPGA, YDCA and SPY) and semi-selective media (SCM, D2ANX). Besides the systemic nature of the pathogen was assessed through formation of biofilm like structures in xylem sap (XS), minimal medium, LB broth and in distills water under in vitro condition. | Evaluation of different growth media for Clavibacter michiganensis subsp michiganensis and formation of biofilm like structures
