Peptone from Soymeal (Soy Peptone) – Enzymatic Digest for Microbiological Media

Peptone from Soymeal is a premium, animal-free nutrient derived from papaic digestion of non-GMO soybean meal. It delivers a rich, reproducible supply of peptides, free amino acids, carbohydrates, vitamins, and growth factors essential for the cultivation of bacteria, yeasts, and fastidious organisms across microbiological, fermentation, and biotechnology applications.

Exact composition varies naturally between batches, as is normal for a plant-derived digest. A Certificate of Analysis is issued per lot — see the COA tab.

• Plant-based, animal-free — sourced from non-GMO soybeans, suited to vegan and animal-component-free media
• Rich nutrient composition — abundant peptides, amino acids, carbohydrates, and growth factors for robust microbial growth
• High total nitrogen (13.0–15.5%) — supports reliable biomass and metabolite yields
• Completely water-soluble — dissolves rapidly for straightforward, uniform media preparation
• Batch-to-batch consistency maintained through in-house QC on every production lot
• Cost-effective alternative to animal-derived peptones

• Microbiological culture media (bacteria, yeasts, moulds)
• Industrial fermentation & bioprocess development
• Biopharmaceutical production (antibiotics, vaccines, proteins)
• Food & beverage fermentation research (brewing, yogurt, soy sauce)
• Animal-free & plant-based media formulations
• Routine microbiology & quality-control laboratories

As an enzymatic digest of soybean meal, this peptone supplies readily assimilable peptides, free amino acids, carbohydrates, and B-complex vitamins to support microbial growth without relying on animal-derived raw materials — providing a plant-based alternative to casein- or meat-derived peptones in culture media and fermentation formulations.

Not classified as hazardous according to GHS criteria (AU WHS Regulations 2011). Derived entirely from food-grade plant material (soybean meal). No hazard pictograms, signal word, or hazard statements required. Standard laboratory precautions apply.

Note: derived from soybean — individuals with a known soy allergy should avoid unnecessary skin/inhalation exposure to dust.

Dispose of as general laboratory waste in accordance with local regulations. Autoclave any inoculated/contaminated material before disposal.

Not classified as dangerous goods under ADG, IATA, or IMDG. No special transport requirements.
