Description

Hiveg WL (Wallerstein Laboratory) media are formulated as described by Green and Gray for the examination of materials
encountered in brewing and for industrial fermentations containing mixed flora of yeast and bacteria. WL Nutrient and WL Differential Media are used in combination. The WL Nutrient Agar plate is incubated aerobically to give a total yeast count while one
WL Differential Agar plate gives the count of acetic acid bacteria, Flavobacterium , Proteus and thermophilic bacterial
count when incubated aerobically. The other WL Differential Agar Plate is incubated anaerobically for the growth of lactic
acid bacteria and Pediococcus.
