Fortification of selenium compound in brown oyster mushroom (Pleurotus pulmonarius and Pleurotus sajor-caju)

Selenium (Se) is one of the most important micronutrients needed for human health. However, the content of Se compound in animals and plants isrelativelysmallin order to meet recommended intakes of Se. Therefore, Se fortification in food source, such as mushroom, is needed.

Description
Summary:Selenium (Se) is one of the most important micronutrients needed for human health. However, the content of Se compound in animals and plants isrelativelysmallin order to meet recommended intakes of Se. Therefore, Se fortification in food source, such as mushroom, is needed. In this study, fortification was carried out by adding sodium selenite to the growth media (the mixture of sawdust and OPEFB) of brown oyster mushrooms included Pleurotus pulmonarius and Pleurotus sajor-caju, in various concentrations of 100, 200, 300, and 400 ppm. The results showed that the highest absorption of Se in P. pulmonarius and P. sojur caju (3.51 and 2.31 %, respectively) obtained from 200 ppm sodium selenite addition. High concentrations of sodium selenite in baglog media tend to inhibit mycellium growth and the production of mushroom fruiting body. The additions of 200 ppm sodium selenite in baglog media of P. pulmonarius and P. sajor-caju were the best treatment in term of the fastest mycelium coverage in 40 and 37 days with the highest biological efficiency ratio (BER) value of 18.80 and 17.89 %, respectively.
