BSU prof discovers Cordillera tree good for growing shiitake

LA TRINIDAD, Benguet -- Chipped branches of Alnus tree endemic to the Cordillera are good for growing Shiitake mushrooms, which are noted for their anti-cancer properties.

Dr. Bernard S. Tad-awan, a professor of the College of Agriculture of the Benguet State University here, found out that the chipped branches of the Alnus tree mixed with sawdust, rice bran and lime can be good growing media for Shiitake mushrooms.

The study, entitled “Using chipped Alnus as substrate f or Shiitake (Lentinulaedodes) in growing bags,” noted that since it is a nitrogen-fixing tree, Alnus actually helps improves soil fertility.

The health benefits of the Shiitake mushroom fueled Dr. Tad-awan’s interest in undertaking a study to intensify its production.

Shiitake mushroom contains lentinan, a polysaccharide, which is an helps restore the vitality of the immune system.

Lentinan is responsible for the mushroom’s reported anti-carcinogenic, anti-tumor, anti-viral and anti-bacterial effects, Tad-awan said.
