Changes in low molecular weight carbohydrates composition and chitin throughout the cultivation stages ofPleurotus ostreatus

  • Yasushi Obatake


Changes in contents of soluble low molecular weight carbohydrates and chitin in a sawdust-rice bran medium during mycelial growth ofPleurotus ostreatus in bottle cultivation were examined in relation to fruit-body yield of nine stocks. Glucose, mannitol, inositol, sucrose, and trehalose were detected in cultures after mycelial spreading. No significant correlation was observed between contents of soluble low molecular weight carbohydrate during mycelial growth and the fruit-body yield. Negative correlation was found between trehalose content in post-harvest cultures and the fruit-body yield. Chitin content in cultures decreased in the fruiting stage. Positive correlation was detected between chitin content of fruit-bodies and the decrement of chitin in post-harvest culture caused by fruit-body growth.
