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 Orange Serum is a medium used for the isolation, cultivation and enumeration of microorganisms associated with spoilage of citrus fruits and derivates, such as lactic acid and acetic acid bacteria, yeasts and moulds.
This medium is recommended by the APHA for the examination of fruit beverages.
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 32.5 ± 2.5°C for 3-5 days.
INTERPRETING RESULTS
Determine the microbial count and report as colony forming unit (CFU) per ml of test sample. Further tests can be performed to differentiate and identify the colonies.
APPEARANCE OF THE MEDIUM
Whitish pad. Yellowish 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
