Data are expressed as mean ± SD (n = 5), and a–d mean significantly different (p < 0.05) by a Tukey test in the same group with different time points. CON, the blank control (no additional carbon source supplement); INU, the positive control (INU supplement), and LDSPs, the experimental group (LDSPs supplement).
