February
Week 1
Introduction to anaerobic facilities for new members
Week 3
Making of NaS solution.
Making of formate media.
Week 4
Creation of transformation buffer (TB).
First geraniol extraction efficiency test with balch tubes.
March
Week 1
Creation of geraniol standards for gas chromatography (GC) analysis/calibration through serial dilutions.
Week 3
Creation of more formate media.
Creation of general salts solution.
Creation of glycylglycine buffer.
April
Week 1
Learning about ribosome binding site library (RBS) and our metabolic Optflux model.
Week 2
Made agar plates
Creation of fresh wild type (WT) stocks.
Week 3
Created diluted puromycin
May
Week 4
Inoculation and revival of frozen stocks.
June
Week 1
Determined the optical density (OD) of the previously revived cultures.
Week 2
Restriction digestion, purification, and ligation of pMEV4 and PCR products (C1 and C2).
Transformation by heat shock, plated the cells, made an agarose gel and ran the products on it.
Picked colonies from the previous day of plating.
Plasmid extraction, digestion, gel electrophoresis, and verification.
Week 3
Revival of pAW50-mCherry frozen stock.
Revival of S0001 (WT) frozen stock.
Week 4
Prepared the revived cultures for fluorescence microscopy.
Fluorescence microscopy training.
Anaerobic transformation of RBS libraries 1-12 into M. maripaludis.
Puromycin enrichment of transformants.
Made glycerol stocks of original transformants.
Fluorescent microscopy of transformants/pAW50-mCherry/S0001.
July
Week 1
Took ODs of the native RBS and library 1 and 2 (12; L-1; L-2 respectively).
Plated the 12, L-1, and L-2 cultures.
Dispensed media to test tubes.
Picked colonies form the plates.
Week 2
ODs from last weeks picked colonies were taken.
Made frozen stocks of RBS colonies,
Sub-cultured parent strains.
Researched primary literature on mCherry maturation.
Began developing a protocol for oxygen maturation of mCherry.
Week 3
Made frozen stocks of RBS colonies and sub-cultured parent strains.
Re-subcultured and revive pAW50-mcherry.
Subcultured the parent strains of WT and native RBS (12) into triplicates. The triplicates were wrapped in foil to prevent any photobleaching.
The pAW50-mcherry came up and then all samples were taken to a plate reader to perform fluorescence tests.
Week 5
Filled out and submitted safety form.
The geraniol extraction efficiency experiment was performed.
- Left the organic phase to dry over night and be resuspended to test for voltility.
Track selection.
August
Week 2
Geraniol synthase containing cells (GS) were inoculated into triplicates of varying concentrations of puromycin.
- The previous geraniol extraction methods were repeated with these new GS samples.
Week 3
Geraniol standards were made to be test on GC/MS.
We did an extraction efficiency test between batch tube vs. separatory funnel.
Testing of geraniol on the GC/MS was done.
Week 4
Cells containing our pMEV4 plasmid with native RBS were inoculated into 5mL of rezasurin free (RF) media with varying levels of puromycin concentration.
ODs were taken of the samples and they were placed into darkness.
Week 5
The cells were prepared for the plate reader as per the first plate reader preparation protocol.
The plate reader results were in conclusion and a new protocol was required.
