Media will not solidify



Not enough agar
Insufficiently mixed

Add more agar> 20 grams/liter.


Spores will not germinate

Inviable spores

Agitate before pouring.
Increase sterilization time to at
least 30 minutes at 15 psi.
Obtain fresher spores.

Soak in 5 cc. of sterilized.
water for 48 hours.
Place one drop of spore
solution per petri dish.
Improperly formulated media

See page 90.

Spores germinate with
mold contaminants
("powdery mildews")

Contaminated spores

Isolate & transfer "white
spots" from one another to
new media dishes. Always
move mycelium away from

Spores germinate with
bacterial contaminants

Contaminated spores

Use antibiotic media. (1/15 1/20 g/liter of gentamycin
sulfate). "Sandwich" spores
between two layers of antibiotic media. Isolate mycelium
when it appears on top surface.

Mycelium grows then
dies back

Poor Media Formulation

See page 90.

Over-sterilized Media

Sterilize for less than 1 hour
at 15 psi.
Acquire new strain.

Poor strain

Contaminants appear
along inside edge of
petri dish

Contamination airborne in

Filter lab air, clean lab. Look
for source.
Wrap edges of petri dishes
with tape or elastic film after
pouring & inoculation.
