Entry title
- Checked plates from 8/5
- Only + control on chloro and RBS-TesA on cholro had growth.
- Obtained acc plasmid (chloro resistance). Started plate and liquid colonies.
Ethanol:
- At 8:30 AM, O.D. of cells was approx. 1.2
- Resuspended in 30 ml PBS, adjusted O.D. to match at 1.0, resuspended in PBS again
- Began resting cell assay (9:15 AM):
- -Flask 1: 1 g/L pyruvate (.03 g)
- -Flask 2: 3 g/L pyruvate (.09 g)+ 1 g/L glucose (.03 g)
- -Flask 3: 3 g/L pyruvate (.09 g)(no glucose)
- Flasks were kept in 32°C shaker/incubator with 1 ml samples taken for Hrs. 1,2,3,6, and 8. (24 Hr. sample will be taken tomorrow)
- Made standards of ethanol and pyruvate to be run on the HPLC:
- Standards were first made of the max possible amount of each substance present in the system. (in 30 ml) These concentrations were then used as a stock to be diluted for subsequent concentrations
