Abstract
The proximate nutrient potential, phytochemical screening and vitamin B-composition of Pleurotus ostreatus (P.O) cultivated by three substrate organic supplementation techniques (avocado seed supplementation (AVOS), whole wheat supplementation (WWS) and soya bean + avocado + wheat + corn supplementation (SAWCS) were determined using standard methods. Proximate nutrient potential revealed that (SAWCS) had the highest crude protein potential (35.75 ± 0.03) and AVOS the least (31.62±0.02). SAWCS had the highest crude fibre potential (29.0±0.06) followed by WWS (26.91± 0.04) and AVOS the least (21.91±0.02). Qualitative phytochemical screening of the ethanol extract of P. ostreatus samples highlighted the presence of alkaloids, triterpinoids and steroids. B1-vitamins observed and their respective percentage daily values were 0.90 mg/100 g and 7.5% for AVOS, 1.23 mg/100 g and 10.3% for SAWCS; and 2.07 mg/100 g and 17.2% for WWS. Also, B2-vitamins observed and their respective percentage daily values were 1.60/100 g and 12.3% for AVOS, 0.20 mg/100 g and 1.5% for SAWCS and 1.11 mg/100 g and 8.5% for WWS. These results showed that P. ostreatus cultivated by substrate organic supplementation techniques was rich in crude protein, crude fibre, vitamin B1 and bioactive substances and suggest the employment of the technique in the improvement of mushrooms (during cultivation) for food, feed and medicinal formulations.
