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.
