Overview
Beef Extract B105 is a casein and meat-derived extract, used as a nitrogen and growth-factor source in culture media. It is suited to the cultivation of lactic acid bacteria, probiotics and yeast. Contains milk allergen. Supplied by STBIO MEDIA with a COA for every batch; samples and specifications are available on request. This is the Halal-certified version.
Beef peptone or beef extract
Beef peptone is enzymatically hydrolysed meat protein, mainly peptides, and the main nitrogen source in nutrient media. Beef extract is the water-soluble extract of meat, naturally containing vitamins, minerals and small nitrogenous molecules; it is used in small amounts mainly for growth factors. Fastidious organisms and nutrient media often use both. Where Halal or bovine-free material is required, look at soy, yeast or plant peptones instead.
