dust can be aged up to one year, which is said to improve its moisture holding capacity. Presoaking
the sawdust prior to mixing in the bran is an effective way to achieve the required 60% moisture optimum. A firm squeeze of the mixture should produce only a few drops of water between the fingers.
If the mixture has too much moisture, loose wafer collects in the bottom of the substrate container, a
condition predisposing the culture to contamination.
The substrate can be filled into a number of different containers. Mason jars, polypropylene jars

or high density, heat-resistant polyethylene bags are commonly employed. The containers are
closed and sealed with a microporous filter. They are sterilized at 1 5 psi for 60-90 minutes. After
sterilization the containers are cooled to ambient temperature and inoculated. The inoculum can be
either grain spawn or sawdust-bran spawn.
During incubation substrate filled plastic bags can be molded to the desired cropping form.
Common shapes are round mini-logs or rectangular blocks. Some Pleurotus growers mold the
