Key points

  • Effects of phytohormones including indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) and 1-naphthaleneacetic [corrected] acid (NAA) on mycelial growth of medicinal mushroom Phellinus linteus were investigated
  • Under the optimal IAA, IBA and NAA concentration of 1.0, 1.5 and 5.0 mg/l, the maximal mycelial diameter reached 8.6 +/- 0.4, 7.3 +/- 2.6 and 9.0 +/- 1.0 mm, respectively
  • The mycelial biomass and exopolysaccharide (EPS) production with addition of 5.0 mg/l NAA in a shake flask were 6.24 +/- 0.18 g/l at 168 h and 0.86 +/-0.01 g/l at 192 h, which were enhanced by 15.98 and 56.36% compared to the control, respectively
  • However, the molecular weight and infrared spectrum of EPS were coincident with the control
  • Results indicated that NAA at the proper concentration was beneficial in stimulating mycelial growth and EPS biosynthesis, whereas it could not alter the molecular structure of EPS
