HIMEDIA Yeast Carbon Base, M141, Microbiology Culture Media, Dehydrated Culture Media, Specialty Medium, Yeast Identification, Nitrogen Assimilation, Powder, 100 g
Yeast Carbon Base is the defined medium for classifying yeasts by their ability to assimilate individual nitrogen compounds. It supplies dextrose as the carbon source together with a complete background of amino acids, vitamins, trace elements and mineral salts, so the analyst varies only the nitrogen source under test. This makes it a standard reagent in yeast taxonomy and identification, complementing Yeast Nitrogen Base in auxanographic assimilation studies. Dehydrated powder, store in a cool dry place. Packaged as 100 g.
HIMEDIA Chloramphenicol Yeast Glucose Agar, M1008, Microbiology Culture Media, Dehydrated Culture Media, Selective Agar, Yeast and Mould Enumeration, Dairy Products, Powder, 500 g
Chloramphenicol Yeast Glucose Agar is a selective medium for enumerating yeasts and moulds in milk and milk products. Yeast extract and dextrose support vigorous fungal growth while incorporated chloramphenicol suppresses accompanying bacteria, giving clean, countable plates, final pH 6.6. Its low pH dependence on antibiotic selection makes it well suited to dairy and food mycology where reliable fungal recovery is essential. Dehydrated powder, store in a cool dry place. Packaged as 500 g.
