Glucose is known to repress lac promoter expression.
LB media (1% tryptone, 0.5% yeast extract, 1% NaCl) is largely
used for media for overproducing cloned gene products.
gene expression under the regulation of lac promoter is repressed by
glucose in the media.
I am curious how much glucose exists in LB.
