Beef Extract Powder

Beef Extract Powder

Microbiological Nutrient Base for Culture Media & Fermentation

Catalog Number: AS-1135

Overview

Beef Extract Powder (AS-1135) is a water-soluble, dehydrated nutrient concentrate produced by the controlled enzymatic digestion and extraction of lean beef muscle tissue. It is a rich natural source of amino acids, peptides, B-group vitamins, nucleotides, organic acids, minerals, and growth factors, making it one of the most widely used components in microbiological culture media worldwide.

Due to its balanced nutritional profile and excellent solubility, beef extract is extensively used as a general-purpose growth supplement in bacteriological media, supporting both fast-growing and nutritionally demanding microorganisms.

Ausamics Beef Extract Powder is manufactured to deliver consistent nutrient composition, reliable performance, and batch-to-batch reproducibility for laboratory and industrial microbiology applications.
