Effect of NaCl concentration on the accumulation of Nα-acetyl-α-lysine in S. halodurans H3B36.
(a) Growth curves and sampling points for S. halodurans H3B36 cells cultured in GMH medium containing 2% or 14% NaCl at 30 °C and pH 7.0; 2%-OD600 and 14%-OD600 represent the OD600 of the cells cultured at 2% and 14% NaCl, respectively. (b) The concentration of Nα-acetyl-α-lysine accumulated in S. halodurans H3B36 at every corresponding sampling point. Intracellular amounts of Nα-acetyl-α-lysine were calculated based on cellular dry weight; 2%-NaAL and 14%-NaAL represent the intracellular amounts of Nα-acetyl-α-lysine at 2% and 14% NaCl, respectively.
