  1. Values in same column not connected by the same letter are significantly different, p < 0.05.
  2. NEP - Nitrogen consumed during exponential phase.
  3. NSP - Nitrogen consumed during stationary phase.
  4. NSP rate - Nitrogen consumption rate during stationary phase.
  5. TN100% - Time necessary to consume all nitrogen.
