Karin Kallander Monitor drug stocks: One technological solution could be through the use of bar coding of medicines, to track and trace stocks, sales, brands across geographies in real time.
The veteran mezzo-soprano Ann Murray, as Marcellina, and the blustery baritone Andrew Shore, as Bartolo, who have their own reasons for trying to derail Figaro's marriage to Susanna, bring not a trace of stock comic posturing to their winning portrayals.
Whereas the glucose, MgSO4 and trace elements stock solutions were prepared and autoclaved in separate vessels.
The composition of the mineral salt medium (MSM) was as follows (g L−1): 1.5 NH4NO3, 1.5 K2HPO4·3H2O, 0.2 MgSO4·7H2O, 1.0 NaCl and 1 mL of trace element stock solution.
In addition, 5 mL/L of a trace metal stock solution [ 35] was added.
All chemicals for PTM1 trace salts stock solution were from Riedel-de Haën (Seelze, Germany), except for biotin (Sigma, St . Louis MO, USA), and H2SO4 (Merck Eurolab).
Chemostat medium contained per liter: 55 g glucose· 1H2O, 2.5 g KCl, 1.0 g MgSO4· 7H2O, 0.035 g CaCl2· 21.8, 21.8 g (NH4 2HPO4 and 2.4 ml PTM1 trace salts stock solution; furthermore the pH was set to 5.0 with 25% HCl.
The chemostat medium contained (per L): 13.4 mL H3PO4 (85%), 0.47 g CaSO4, 9.1 g K2SO4, 7.5 g MgSO4·7H2O, 2.07 g KOH, 20.0 g methanol or glycerol, 0.5 mL antifoam, and 4.35 mL trace salt stock solution.
The media were as follows: Batch medium contained per liter: 2.0 g citric acid, 12.4 g (NH4 2HPO4, 0.022 g CaCl2· 2H2O, 0.9 g KCl, 0.5 g MgSO4· 7H2O, 40 g glycerol, 4.6 ml PTM1 trace salts stock solution.
Batch cultivations were performed in basal salt medium, containing (per L): 26.7 mL H3PO4 (85%), 0.93 g CaSO4, 18.2 g K2SO4, 14.9 g MgSO4·7H2O, 4.13 g KOH, 40.0 g glycerol, 0.5 mL antifoam, and 4.35 mL trace salt stock solution.
