Overview
Malt Extract 170SD is a water-soluble fine beige powder, produced by blending the special selected malt extract, yeast peptone and plant peptone together. It contains reducing sugars, proteins, in readily and easily absorbable pre-digested forms such as peptides and amino acids, minerals and growth factors.
Choosing a medium for yeasts and moulds
Potato Dextrose Agar and Sabouraud Dextrose Agar are the two general-purpose media most often used for yeasts and moulds. The former promotes mycelial growth and sporulation for morphological work; the latter's low pH itself suppresses bacteria. Malt-based media suit the cultivation and maintenance of yeasts, while the Czapek range is used for the taxonomy of filamentous fungi such as Aspergillus. Broths are for propagation, agars for enumeration and isolation.

Food grade versus laboratory grade
Most culture media suppliers use laboratory-grade raw materials, which are held to lower standards for heavy metal residues, microbial contamination control, and traceability. That is adequate for pure research but not for applications with stricter raw-material requirements. STBIO manufactures with food-grade raw materials throughout, in a facility certified to ISO 22000 food safety management.
- Food microbiology laboratories working to ISO 17025 or equivalent requirements
- Biotech manufacturers exporting fermentation products and needing full raw-material traceability
- Organisations with ESG or compliance audit requirements across their supply chain
- Companies sourcing both Halal and non-Halal products who need one consistent material grade
Frequently asked questions
01Do I need to suppress bacterial growth in fungal testing?
It depends on the sample. For foods or environmental samples with high bacterial loads, the pH is usually lowered or antibiotics are added to suppress bacteria. Follow the requirements of your chosen method; we are happy to advise.
02Which organisms is it suitable for?
Lactic acid bacteria, S. cerevisiae. See the cultural response table and the specification sheet.
03Is it free of animal-derived components?
Yes. This product is animal-origin-free, suitable for animal-free formulations and Halal requirements; a declaration is available on request.
04Is the raw material non-GMO?
Yes. The raw material is non-GMO; the supplier declaration can be provided with the COA.
05Can it be used for food-grade applications?
Yes. It is made from food-grade raw materials in an ISO 22000 certified facility and is suitable for culturing starters for fermented products that are consumed directly.
06How should it be stored, and what is the shelf life?
When stored in sealed containers, at ambient temperature in dry and clean conditions, the expected shelf life is 3 years.
