Overview
Peptone from nitrate is a protein hydrolysate produced through enzymatic or acid digestion of animal or plant proteins. It serves as a fundamental component in microbiological culture media, providing the necessary nitrogen sources for bacterial proliferation. Unlike simple nitrogen compounds, peptones contain a spectrum of amino acids, oligopeptides, and growth factors that support diverse microbial requirements. The nitrate component enhances its utility for specific bacterial species that can utilize nitrate as an alternative electron acceptor.
Physical and Chemical Properties
This peptone variant typically appears as a hygroscopic powder with variable coloration depending on the protein source and processing method. Its solubility profile makes it ideal for liquid media preparation, dissolving completely without residue. The material demonstrates stability at room temperature but may degrade when exposed to moisture or extreme heat. Analytical characteristics include total nitrogen content (typically 12-14%), amino nitrogen (30-40% of total nitrogen), and low ash content (<15%).
Main Applications
Primary use occurs in clinical and industrial microbiology for culturing nitrate-reducing bacteria, including certain pathogenic species. It forms the base component of selective media like Nitrate Broth for microbial identification. In biopharmaceutical production, nitrate peptone supports cell growth in vaccine development processes. Food testing laboratories utilize it for detecting nitrate-utilizing contaminants, while environmental researchers apply it in wastewater treatment studies.
Safety and Storage
While classified as non-hazardous, proper handling precautions should be observed. Powder inhalation may cause respiratory irritation—use dust masks during large-scale handling. Storage requires protection from humidity to prevent caking. Manufacturers typically recommend 2-3 year shelf life when stored in original packaging below 25°C. Opened containers should be resealed with desiccants and used within 6 months to maintain performance consistency.
B2B Procurement Guide
Industrial buyers should specify the protein source (animal/plant origin) and processing method (enzymatic/acid hydrolysis) as these affect microbial growth performance. Request certificates of analysis for critical parameters: total nitrogen, amino nitrogen, and microbiological purity. For fermentation applications, verify batch-to-batch consistency through small-scale trials. Bulk purchases (25kg+) commonly offer 15-20% cost savings, but ensure proper storage capacity exists. Leading manufacturers include BD Biosciences, Thermo Fisher Scientific, and HiMedia Laboratories.
