Establishment of a submerged culture medium for a native strain of a Poliporal mushroom
The effect of two agitation speeds (80 and 100 rpm), two carbón sources (glucose and sucrose) and three initial pH (5.5, 6 and 6.5) was evaluated on total phenol production, antioxidant activity, mycelial growth and substrate consumption of a native Poliporal fungi strain in submerged culture.The greatest mycelial growth (10 g/L) was obtained by the third day with an agitation speed of 80 rpm, sucrose as carbón source and initial 5.5 pH. Máximum phenol production and antioxidant activity were observed on the same day, reaching 0.18 g GAE/L and 0.28 TEAC (mM/mL) valúes, respectively, for both agitation speeds using glucose as carbón source and an initial 6.0 and/or 6.5 pH for phenol and initial pH 5.5 for antioxidant activity.Keywords: antioxidant activity, mycelial growth, phenol, submerged culture.
