Assessment datepalm fibers extract agar with other lignocellulose residues on mycelial growth of pleurotus eryngi

Abstract EN

The influence of various culture media on the mycelial growth of Pleurotus eryngii(king oyster mushroom)was investigated on five agro-substrate agar media; wheat straw extract Agar (S1EA), 70% wheat straw, 20% white sawdust and 10% date palm fibers extract agar (S2EA), 50% wheat straw, 30% white sawdust and 20% date palm fibers extract agar (S3EA), white sawdust extract agar (S4EA)and date palm fibers extract agar (S5EA)media.The best medium for mycelial growth of Pleurotus eryngii was date palm fiber extract agar (S5EA) while less mycelial growth was on white sawdust extract agar (S4EA).In significant difference (P<0.05), the periodic growth after 4 days was 9.4 mm day-1 on fibrillum extract agar medium (S5EA), while the lower growth was 6.7 mm day-1on S4EA.The best cumulative growth of mycelia was 9.4 mm day-1 on S5EA medium, while the less growth was 6.3 mm day-1verified on S4EA, which take more time for covering plate by mycelia.
