 ABSTRACT

The aim of the study was to investigate the suitability of locally available substrate Eleusine coracana (finger millet) straw for the cultivation of different Pleurotus species in terms of yield, biological efficiency, nutritional contents and antioxidant properties under the native condition of Tawang, Arunachal Pradesh. Four species of oyster mushroom namely Pleurotus florida, P. ostreatus, P. citrinopileatus and P. erygnii were successfully cultivated on finger millet straw in the native condition of Tawang. P. florida and P. ostreatus showed better results in terms of pin head appearance, fruiting bodies maturation, yield and biological efficiency when compared (P≤0.05) to P. citrinopileatus and P. erygnii. Crude protein, fat, total ash, dietary fiber and total carbohydrate content in respective oyster species were found to be in the ranges of 0.70 – 2.37, 0.16 - 0.19, 0.62 – 1.05, 0.69 – 1.40 and 3.31 to 6.47 g/100g of fresh edible portion (EP) respectively. Whereas the values of calcium, magnesium, zinc and iron in the four oyster species were found to be in the ranges of 11.23 – 12.32, 11.02 – 16.21, 1.45 – 1.97 and 1.46 – 2.89 mg/100g of fresh EP respectively. In addition, the Pleurotus species grown on finger millet also showed good antioxidant activity with DPPH radical scavenging assay and hydroxyl radical scavenging assay. The ethanolic extract of P. florida showed the highest DPPH radical scavenging effect (47.71 ± 0.73%) at 1000 μg/ml concentration and strongest hydroxyl radical scavenging activity (56.75 ± 1.19%) at 2.5 µg/ml concentration when compared to other three Pleurotus species. This is the first study evaluating the suitability of Eleusine coracana (finger millet) straw as a substrate for growing oyster species.
