1H NMR spectra (methanol- d4-KH2PO4 in D2O, pH 6.0 extract) of medium on which P. microspora was cultured (Medium 1) and of the control. (a) spectrum of Medium 1 in the range δ 3.7–9.9. (b) spectrum of the control media in the range δ 3.7–9.9. (c) spectrum of Medium 1 in the range δ 4.1–5.5 (carbohydrates range). (d) spectrum of the control medium in the range δ 4.1–5.5 (carbohydrates). The assigned peaks are as follows, 1: vanillyl alcohol; 2: p-hydroxybenzoic acid; 3: p-hydroxybenzaldehyde; 4: vanillic acid; 5: vanillin; 6: glucovanillin; 7: glucose and 8: sucrose
