Effect of nitrate exposure history on the oxygen/nitrate diauxic growth of Pseudomonas denitrificans.
Pseudomonas denitrificans pre-cultured (revived from agar plates) under varying conditions (nitrate absent or present; dissolved oxygen absent or present) was subsequently grown aerobically with or without nitrate present, and finally exposed to anoxic conditions (i.e., aeration stopped and dissolved oxygen stripped from solution). The occurrence and length of diauxic lags following transition from aerobic to anoxic conditions were affected strongly by the nitrate and oxygen exposure history of the biomass.
