glucose solution for autoclave
Glucose, used as model sugar in this investigation, was autoclaved for 20,32 or 44 min in volumes of 0.25. 1.2 and 5 1. The rise in temperature of the solutions was monitored by thermocouples. Glucose degradation was estimated by the rate of cyanide-initiated oxygen consumption.

Then: Stir using hot plate w/ stir bar for ~30min. Next, add MQ water up to 2000mL. Pour into 1L glass bottles. Each container should have ~650mL media. Autoclave: ~40min. . Autoclave: ~40min . How to make LB Liquid: For 2L solution: Add:Use autoclave tape to tape on caps, also put a small bit of autoclave tape on any other items you autoclave. The tape will change color during autoclaving, thus signaling to any future user that the item has really been sterilized. Note: Autoclave tape only .
Alternatively, 5g/L NaCl can be used (Lennox formulation) or no salt (-NaCl). The -NaCl (no salt) version of LB should be used when using salt sensitive antibiotics like hygromycin: for example, when cloning into pSS170. (Alternatively, DNA or DNB can be used for hygromycin selection.) To make liquid LB medium, omit the agar and autoclave as above.ATCC medium: 2207 LB medium with 2.0% glucose Tryptone...10.0 g Yeast extract...5.0 g NaCl...10.0 g#01 LB-Medium Materials: - 10 g/L Tryptone - 5 g/L yeast extract - 10 g/L NaCl - MQ H 2 O Procedure: 1.
