Bone Peptone (Biological Grade) — High Nitrogen, Low Ash, Preferred Raw Material for Microbial Culture

Product Introduction

Bone Peptone is a high‑nitrogen, low‑ash, high‑clarity peptone product made from fresh bovine bone through pancreatic enzymolysis, low‑temperature extraction, refining, and spray drying.
It is rich in peptides, amino acids, and trace elements, and is especially suitable for high‑end biological applications such as biopharmaceutical fermentation, microbiological media production, vaccine manufacturing, and diagnostic reagents.

Raw Material & Process

Product Features

• High Total Nitrogen ≥ 14.5% – Provides sufficient nitrogen source to promote rapid microbial growth

• Amino Nitrogen ≥ 2.5% – Rich in small peptides and free amino acids, easily utilized by microorganisms

• Low Ash ≤ 5.0% – Reduces impurity interference, suitable for precision fermentation

• Excellent Clarity – 2% aqueous solution remains clear and precipitate‑free after heating and cooling, ideal for high‑purity media preparation

• Stable Biological Performance – Verified with multiple standard strains, supporting tests such as hydrogen sulfide, indole, hemolysis, pigment production, etc.
