Genome Deletion

Restriction Enzyme testing in Dam+ve and Dam-ve Strains

An experiment investigating the effects of methylation on the amount of cleavage by varying concentrations of restriction enzymes.

Temporal Control

Diauxic Growth

Growth in the presence of Glucose only

Testing the effects of glucose concentration on cell growth: This experiment will be linked to diauxic growth.
Rationale: A cell culture in the presence of glucose grows exponentially. Once it uses up its resource, it stops growing and the population density saturates.

Growth in the presence of Glucose + Xylose

Testing the effects of different xylose concentrations on cell growth, for a fixed initial glucose concentration: This experiment will be linked to diauxic growth.
Rationale: A cell culture in the presence of glucose grows exponentially. Once it uses up its resource, it stops growing and the population density saturates. However, in the presence of a secondary carbon source, the cells enter a second exponential phase where they grow and saturate once again when the secondary source has been used up.
NOTE: Same raw data file as above!

Thermoinduction

Harvard+GFP results

Testing the effects of temperature on fluorescence output.
Rationale: Genome deletion is repressed at low temperatures, and triggered when the temperature rises. Here, we are testing the p-lambda promoter by attaching GFP to it, in order to show how the fluorescence output varies when the temperature rises. raw data
