manufacturer's recommendations. And some extra time must be allowed for adequate penetration
of steam, especially in densely packed, large autoclaves.
Once sterilized, place the cooker in the laboratory or in a semisterile room and allow the pressure to return to 1 psi before opening. One liter of agar media can generously fill thirty 1 00 x 1 5
mm. petri dishes. Techniques for pouring vary with the cultivator. If only one or two sleeves of petri
dishes are being prepared, the plates should be laid out side by side on the working surface. If more
than two sleeves are being poured or table space is limited, pouring the sterile petri dishes in a vertical stack is usually more convenient.
Before pouring, vigorously shake the molten media to evenly distribute its ingredients. Experienced cultivators fill the plates rhythmically and without interruption. Allow the agar media to cool
and solidify before using. Condensation often forms on the inside surface of the upper lid of a petri
dish when the agar media being poured is still at a high temperature. To reduce condensation, one
can waif a period of time before pouring. If the pressure cooker sits for 45 minutes after reaching 1
psi, a liter of liquid media can be poured with little discomfort to unprotected hands.
Two types of cultures can be obtained from a selected mushroom: one from its spores and the
other from living tissue of a mushroom. Either type can produce a viable strain of mycelia. Each
has advantages and disadvantages.
