Transcriptional profiling of the T. thermophilus HB8 response to tetracycline

ABSTRACT: We observed the expression profile of the total mRNA in Thermus thermophilus HB8 wild-type strain at 10 min after the addition of 50 mM tetracycline. Three wild-type strain of T. thermophilus HB8 were pre-cultured at 70 degC for 16 hours in 4 mL of TT medium containing 0.8% polypeptone, 0.4% yeast extract, 0.2% NaCl, 0.4 mM CaCl2, and 0.4 mM MgCl2, which was adjusted to pH 7.2 with NaOH. The cells (2 mL) were inoculated into 1 L of the same medium and then cultivated at 70Â°C for 6 hours (A600 value being ~0.62). Then the 50 mM of tetracycline was added into the medium, and continued cultivation. Cells were collected at 0 and 10 min time point after the addition of tetracycline, and then crude RNA was extracted. The expression of each mRNA at each time point was analyzed on a GeneChip.
