GYC AGAR 500 grams/bottle (CDL/2026)


RM 521.00


GYC Agar described by Swings (1992) detects the presence of acid-producing microorganisms and is regarded as “standard growth medium” for acetic acid bacteria.

Dextrose is the fermentable carbohydrate providing carbon and energy. Yeast extract is source of vitamins, particularly the B-group. Grown on this medium, Acetobacter will produce clear zones or halos around colonies because the acid being produced will neutralize the CaCO3. Unlike the lactic acid bacteria, acetic acid bacteria are obligate aerobes and so it is necessary to use spread plates. Bacteriological agar is the solidifying agent.
