GVS M-Green Select Broth; 2mL Ampoule

M-Green Select Broth is an improved modification of the liquid medium M-Yeast and Mould Broth. It was developed to improve efficiency of detection and enumeration of fungi in sugar based drinks using the membrane filtration method. This medium has a low pH, which inhibits bacterial growth. Bromocresol green indicates pH change: yellow (acid reaction), green (alkaline reaction). When bromocresol green diffuses into fungal colonies it has an alkaline reaction, allowing identification easily. Metabolic by-products from the developing colonies diffuse into the surrounding medium, further reducing the pH which aids in the inhibition of bacterial growth, but also produces an acid reaction which causes residual bromocresol green to change to yellow. The addition of chloramphenicol further inhibits the growth of bacteria to allow for the development and enumeration of yeast and mould.

GVS provides an extensive range of culture broths and solutions for the cultivation, detection and enumeration of bacteria yeast, fungi, viruses, pathogens and moulds. Each nutrient rich liquid media is specifically developed for use in the analysis of drinking water, surface water, milk, juice, beverages, sugar based drinks, food and pharmaceutical samples. These ready to use liquid medias are packaged in individual pre-portioned ampoules for ease of use. All liquid medias undergo detailed quality control checks in accordance with standard methods, guaranteeing uniform preparation every time. Comprehensive end product testing ensures a stable sterile liquid media for optimal culture growth.
