Any process involving glucose that stops, prevents or reduces the rate of transcription. The presence of glucose in the growth medium inhibits the synthesis of certain enzymes in bacteria growing on the medium. For example, transcription of some catabolic operons is under negative control by specific repressors and glucose is an anti-inducer of xylose utilization and glycerol kinase. A change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nutrient stimulus. Any process that modulates the frequency, rate or extent of cellular DNA-dependent transcription. Any process involving galactose that stops, prevents or reduces the rate of transcription. Any process that stops, prevents or reduces the frequency, rate or extent of the chemical reactions and pathways involving RNA. Any cellular process that stops, prevents or reduces the frequency, rate or extent of transcription. Any process involving carbon catabolites that modulates the frequency, rate or extent of transcription. Any process involving carbon catabolites that stops, prevents or reduces the rate of transcription. Carbon catabolite repression is a mechanism of genetic regulation in bacteria in which the accumulation of catabolites of one substance in the cell represses the formation of enzymes that contribute to the catabolism of other substances. Any process that stops, prevents or reduces the frequency, rate or extent of cellular DNA-dependent transcription. The cellular synthesis of RNA on a template of DNA.
