GVPC Agar for Legionella
GVPC agar for Legionella is used for the enumeration, isolation and culture of Legionella species in clean water (hot water production, hot sanitary water, swimming pools…) and in dirty water (industrial water, cooling towers…).
The typical composition corresponds to that defined in the standards NF T90-431 and NF EN ISO 11731
Available in 20 or 120 plates (90mm)
Autolytic yeast extract constitutes a primary nutrient leading to Legionella growth.
Activated charcoal decomposes hydrogen peroxide (toxic metabolic by-product), captures the carbon dioxide and modifies the surface tension.
The ACES/KOH buffer maintains the pH and permits aerobic incubation.
Cysteine and ferric pyrophosphate represent indispensable nutritive elements for the growth of Legionella.
α-cetoglutarate is a growth activator for Legionella.
Secondary microflora are inhibited by the association of glycine, vancomycin, polymyxin B and cycloheximide.
