Carbon dioxide and Ethylene Levels during Incubation and Fruiting Stages on Sawdust-Based Culture of Lentinula edodes

The production of volatiles from the sawdust-based culture of Lentinula edodes was monitored during mycelial growth and fruit body first flush for 100 days. Carbon dioxide and ethylene production was recognized in relation to mycelial growth and fruit body development. These two volatiles were released with similar pattern. It was seen that high rates of both volatiles production occurred on days 20 to 30 of fully colonized stage, and day 60 of fruit body veil break stage.

Cultural Characteristics for Inducing Fruit body of various Insect Mushrooms on Polyurethane Foams

Cultural characteristics of various seven strains of lsaria and Cordyceps spp, by cultivating on four different kinds of polyurethane foams (PUF) were investigated. Significantly faster mycelial growth was recorded from Cordyceps ophioglossoides and fsaria atypicola. Highest whiteness was achieved from 1. sinclairii on plant based with 36.5 O/o castor oil and plant based with 2 O/o wood and O.9 O/o sucrose, but petroleum based and plant based with 1 O/o sucrose PUF were best for C. sinensis. Comparing to all PUF whiteness was comparatively much better on plant based with 1 O/o sucrose PUF for six species, while 1. farinose was on plant based with 2 O/o wood and O.9 O/o sucrose. The ergosterol contain was significantly high in 1. sinclairii. Fruit bodies were successfully observed in five species in between 70 to 90 days.
