103753 Yeast Extract for Biotechnology and Microbiology, GranuCult, Merck

Yeast extract (1.03753) is a water-soluble, peptone-like derivative of yeast cells, carefully manufactured through controlled autolysis to preserve naturally occurring B-complex vitamins, amino acids, and minerals. As part of the GranuCult® range, this extract is processed into a granulated format. This specialized granulation ensures rapid and uniform dissolution in water while significantly reducing the formation of airborne dust, making it safer for laboratory personnel by minimizing the inhalation of fine particles. It provides a complete nutritional profile for the cultivation of fastidious microorganisms and is widely used in pharmaceutical, environmental, and food and beverage testing.

Advantages

• Granulated Format: Significant reduction in dust inhalation and laboratory contamination; prevents clumping even under humid conditions.
• Nutrient-Rich: High concentration of B-complex vitamins, organic nitrogen, and essential trace elements.
• Superior Solubility: Rapid and uniform dissolution in water, resulting in clear, bright media solutions.
• High Reproducibility: Homogenous distribution of components ensures consistent batch-to-batch performance in fermentation and culture media.
• Animal-Free: Purely vegetable/yeast origin, suitable for applications requiring non-animal derived components.
