STERILE TECHNIQUE
CAUSE

SOLUTION

Media fails to solidify.

Insufficient quantity of agar or
distribution thereof.

Thoroughly mix media before
pouring.

Media boils out of vessel or
flask containing it.

Excessive escape of steam
from pressure cooker.

Do not vent pressure cooker
until reaching 1 psi.

PROBLEM

Agar Culture

Grease pressure cooker seals

with thin film of petroleum jelly.

For pressure cookers using 5,
10, 1 5 lb weights, do not
operate so steam escapes.

Contamination occurs in petri
dishes after pouring media
but before inoculation.

High contaminant spore load
in lab.

Clean, paint lab. Install laminar flow hood.

Improper media preparation
technique.

Allow pressure cooker to cool
in sterile setting before opening.

Contaminated pressure
cooker (bacteria).

Sterilize pressure cooker for
24-48 hours at 1 5 psi.

No growth from spores or tis-

sue transferred.

Wrong pH.

See media preparation

Old or dehydrated spores.

Soak in sterilized water for
1 2-24 hours.

Scalpel or loop too hot.

Cool tool before contacting
spores or tissue.

Sugar in media caramelized.

Lower sterilization pressure
and temp. to recommended
levels.
