Easy DryTM are absorbent pads saturated with a sterile, dehydrated culture medium. Each pad is pre-plated in a Petri dish and is immediately ready to use after pouring sterile distilled or deionized water on it. Easy DryTM are optimal for the examination of large sample volumes by the membrane filter method.
Easy DryTM M-Green Yeast & Mold is a medium used for the isolation and enumeration of yeast and mold in wine, soft drinks, concentrates, sugar products and potable water.
PREPARATION
1.
Cut open a bag and remove the number of Easy Dry plates needed.
2.
Moisten the pad contained
in the Petri dish with 2.2 ml of sterile distilled or deionized water.
3.
Wait 5 minutes before
using.
TEST PROCEDURE
Filter the sample through a filter membrane (0.45 μm pore diameter). Transfer the membrane onto a plate containing a just rehydrated pad. Incubate aerobically at 20-25°C or at 30-35°C, depending on the target of the investigation, for up to 7 days. Read plates twice; once at 2 days, and again at 5-7 days per user discretion.
INTERPRETING RESULTS
Examine the membrane for growth. The colonies are green due to diffusion of Bromcresol Green into the colonies.
APPEARANCE OF THE MEDIUM
Whitish pad. Greenish once rehydrated.
STORAGE
Store at 10-25°C away from light. Do not
use the product beyond its expiry date on the label or if product shows any
evidence of contamination or any sign of deterioration.
SHELF LIFE
2 years.
