MES 1.95 g 1.95 9.988
2 Add solutions A, B, and Trace mineral solution (see recipes below):
Solution A (100x solution) 2.00 ml - -
Solution B (500x solution) 1.50 ml - -
Trace mineral solution (100x) 10.00 ml - -
3 pH the media to 6.0 and gas the flask containing the media with CO2 for 20 min at least. Gas first culture tube in rack and place 5 ml of media in previous tube. Place stopper on loaded culture tube, crimp tube cap onto stopper. Autoclave the medium for 20 min., 121°C. Add 1 ml of O2 to each tube before inoculation. After the inoculation the tubes are pressurized with H2 (138 KP).
