Quad Plate (NBB, WLD, Nutrient, Wild Yeast) Agar pre-poured plates (pack of 10)
Four quadrant plate that allows for selection of a wide variety of microbes in the brewery environment. Quadrant I: NBB – Selective media for the fast and reliable detection of beverage spoiling microorganisms, such as Lactobacilli, Pedicoccus, Pectinatus and Megasphaera, in all samples that arise in breweries, as well as for the wine industry. Contains chlorphenol red to detect acid-secreting organisms (plate changes color). Quadrant II: LCSM (Lin’s Cupric Sulfate Medium). Selects for wild yeast in yeast slurries and wild yeast captures. This media typically allows growth of non-Saccharomyces yeasts, but some Saccharomyces yeasts such as Saccharomyces cerevisiae var. diastaticus will also grow on this medium. Isolate a wild yeast strain and use it to make some awesome beer! Quadrant III: WLD – Supports growth of various bacteria and yeast, but contains cyclohexamide to inhibit growth of brewer’s yeast. Contains bromocresol green that is used as a pH indicator to detect acid-secreting organisms (plate changes color). Quadrant IV: Nutrient – Will allow growth of many different microbes in the beer brewing environment, including yeast and bacteria.
