Abstract
Pleurotus djamor also known as pink oyster mushroom is known to produce light to dark pink colored fruiting bodies which depends on the strain and the growing conditions. The effect of the different light conditions particularly light emitting diode (LED) on the mycelial growth and fruiting body production on P. djamor was investigated. The radical scavenging activity and total phenolic content of fruiting bodies grown on different illumination conditions were determined. Mycelial under blue LED showed the widest mycelial diamater (79.83 mm) after 4 days of incubation. The highest yield (67.30g) and biological efficiency (13.46%) were noted in blue LED. The most number of fruiting bodies was recorded in alternating light and dark while the longest stipe (21.67mm) and widest diameter of pileus (41.00mm) were observed in total darkness and blue LED, respectively. Fruiting bodies harvested under blue LED had the highest radical scavenging activity (68.44%) while those grown under flourescent light contain the highest total phenolic content (121.29 mg GAE/g sample).
