PROBLEM

CAUSE

SOLUTION

Contaminants localized
to point of transfer

Culture contaminated

Isolate new culture.

Scalpel contaminated

Flame sterilize scalpel longer.

Airborne contamination

Filter air & use good sterile
technique.

Contaminated mediaInsufficient sterilization

Increase sterilization time.

Hands upstream of
cultures during inoculation
in airstream of laminar
flow hood

Keep hands downstream of
inoculation site.

Humidity too low

Increase lab rH to 50% or wrap
petri dishes with tape or
elastic film.
Place cultures outside of
airstream.

Contaminants appear
equally over the surface
of agar media

Media evaporates, cracks,
before colonization is
complete

Culture in airstream

GRAIN CULTURE
Grain spawn contaminates
before opening, before
inoculation

Bacteria endemic to grain

Contaminants enter during
cool-down

Mycelium does not grow

Too dry

Soak grain overnight to
trigger endospores into
germination, making them
susceptible to heat
sterilization.
Filter air during cool-down
or open pressure vessel at 1 psi
in clean room.
Over-sterilized. Cook 1-2
hours at 15 psi.
Reduce surface area or porosity
of filter media.

Bacterial contamination

Soak grain spawn overnight.

Boil grain in a cauldron before
sterilization.
