II09 CRP-GFP fluor different media.jpg

Cells with BBa_K200018 were grown overnight in various different media, and the GFP fluorescence was measured.

After overnight culture, the corrected fluorescence of glucose is almost negligible, showing that glucose represses the PcstA promoter strongly.

For all the other secondary carbon sources, 10% Casamino Acids in M9 shows the highest corrected fluorescence at 22000.

For effective gene expression, not only must the promoter activity be strong, but there must also be enough cells expressing the genes. Therefore, OD600 is also a critical factor.

Due to the exceedingly low OD600 in 0.5% Lactose in M9, the medium cannot be used even though it induces relatively high fluorescence.
