Assays

E. coli MG1655 and ∆sdhC and ∆frdA isogenic mutant strains were characterized in batch growth curves aerobic and anaerobically. Optical density, glucose consumption and by-product accumulation were measured during growth.

Glucose transporter mutants were analyzed under aerobic and aerobic conditions in batch cultures with glucose as substrate. Acetate formation rates and glucose consumption rates were measured, as well as extracellular cAMP concentrations.

Mutant strains which lack one or more of the glucose transport systems were analyzed in aerobic chemostat cultures and compared to batch cultures.

MG1655 and mutant strains with defects in glucose transport systems were analyzed in aerobic and anaerobic batch cultures.

This assay describes how to analyze gene expression rates via RT-PCR.

This document describes by-product formation rates measured in MG1655 at steady-state conditions in Infors-Multifors-Bioreactors.
