Cells of A. mimigardefordensis strain SHX22 were first incubated in modified MS medium with 2 g/liter NH4Cl, 10 g/liter glycerol, and 0.4 g/liter yeast extract. After the optical density indicated that the early stationary phase (OD600 of approximately 4.3) had been reached, cells were collected and transferred into the same medium supplied with different concentrations of glycerol (10, 20, 30, 40, and 60 g/liter) and 6 g/liter DTDP as a precursor. After 4 days of incubation, CDW, OD600, and supernatant of the final cultures were also measured. The values are means and standard deviations from three independent experiments. —, below detection limit.
