Yeast Extract Powder | Microbiology & Fermentation Nutrient – Ausamics
$25.00 AUD
Documentation
Ausamics Yeast Extract Powder (CAT: AS-1010) is a highly soluble, complex nutrient source produced by the controlled autolysis and hot-water extraction of Saccharomyces cerevisiae cells, followed by concentration and spray drying. It delivers a rich, reproducible supply of free amino acids, B-complex vitamins, nucleotides, and growth factors essential for the cultivation of bacteria, yeasts, and moulds across microbiological, fermentation, and biotechnology applications.

Key Features & Benefits
Pre-digested nutrients directly assimilable by microorganisms — reduces lag phase and accelerates growth
Rich in B-complex vitamins, supporting fastidious organisms that cannot synthesise these de novo
High and consistent total nitrogen content (≥10%) for reliable biomass and metabolite yields
Freely water-soluble — dissolves rapidly for straightforward media preparation
Batch-to-batch consistency for reproducible experimental results
Compatible with autoclaving (121°C, 15 min) without significant nutrient degradation
Typical Applications
Microbiological culture media (bacteria, yeasts, moulds)
Fermentation and biotechnology research
Antibiotic assay media (e.g. Antibiotic Medium No. 3)
Pharmaceutical microbiology & QC testing
Industrial microbiology & scale-up fermentation
Growth media for fastidious & demanding organisms
Storage & Stability
Store at 10–30°C in a cool, dry, well-ventilated place
Protect from moisture and direct light — hygroscopic product
Keep container tightly closed after each use
Use before stated expiry date printed on packaging
