Abstract
The effect of the initial nitrite concentration on the growth of S. platens is was experimentally investigated using the medium added to the sodium nit rite of 0.0-1.6 kg . m(-3). When the initial nitrite concentration is small er than 0.8 kg . m(-3), the growth rate is greater than that without nitrit e. The specific growth rate had the maximum value and is approximately 1.3 times that of a standard medium when the range of the initial nitrite conce ntration is 0.3-0.4 kg . m(-3). When the initial nitrite concentration is g reater than 0.8 kg . m(-3), the growth rate was smaller than that of a stan dard medium due to nitrite inhibition.
