Characterization of mycobacterial oligopeptide permease system

ABSTRACT: M. tuberculosis strain 1254 wild type (WT) and its isogenic delta Rv3662c-Rv3665c KO (opp KO) and complemented opp::opp were cultured in vitro, in liquid 7H9 media supplemented with OADC and 0.05% Tween 80, 0.5% glycerol, in a 150 mL volume, contained in roller bottles, incubated at 37oC. Growth was monitored as OD600 nm and recorded on a daily basis. In all experiments, the starting OD600 nm was 0.04-0.05. Aliquots were removed at each OD600 nm to make serial dilutions, plate onto 7H10 OADC agar plates for CFU counts. When cells reached OD600 nm of 0.3, 1.0, and 1.5, a 10-30 mL aliquot was taken, centrifuged 3 min at 3000 g, at room temperature, and the supernatant was discarded, with cell pellets being immediately frozen by inclusion into dry ice. Frozen cell pellets were stored at -80o
