Abstract

The effect of thinned fruits, apple, pear and peach, on the mycelial growth of mushrooms was investigated. The growth of mycelia with the addition of thinned fruit was clearly better than that in the control for all the tested mushrooms. The growth rate ofPleurotus ostreatus was faster than any other mushroom. The optimal concentrations of thinned apple, pear, and peach in a solid culture were 1.0%, 1.0%, and 3%, respectively, while in a liquid culture the optimal concentrations were 5,0%, 3.0%, and 5.0%, respectively. WhenPleurotus ostreatus was incubated in a 20-L pilot scale fermenter with 10 L of a liquid medium containing 3% thinned fruit at 25°C and 6 vvm for 10 days, the mass-production of mycelia was 74.2 g/10 L (apple), 96.2 g/10 L (pear), and 86.3 g/10 L (peach). The mycelial yield ofPleurotus ostreatus in a medium containing thinned fruit was 2≈3 times higher than that in the control.
