Bile Salts Mixture

Selective Agent for Enteric Bacteria Culture Media
Catalog Number: AS-1002

Overview

Bile Salts Mixture is a selective inhibitory agent widely used in microbiological culture media for the isolation and differentiation of enteric Gram-negative bacteria. Derived from purified bile acids, this mixture suppresses Gram-positive organisms while allowing the growth of bile-tolerant enteric pathogens such as Escherichia coli, Salmonella, Shigella, and Enterococcus (in appropriate formulations).

Bile Salts Mixture is a key component in many selective and differential media, including MacConkey Agar, Deoxycholate Citrate Agar, and various bile-based enrichment and transport media. It plays a critical role in food safety, water testing, clinical microbiology, and environmental monitoring.

Applications

  • Selective inhibition of Gram-positive bacteria in culture media

  • Component of MacConkey Agar, DCA, SS Agar, and related media

  • Food, water, and environmental microbiology testing

  • Clinical microbiology and enteric pathogen research

  • Media formulation and custom microbiological media development

Key Features

  • Strong inhibition of Gram-positive organisms

  • Supports growth of bile-tolerant enteric bacteria

  • Consistent performance in selective and differential media

  • High purity and batch-to-batch reproducibility

  • Suitable for routine, research, and regulatory microbiology

Principle of Action

  • Bile salts disrupt cell membranes of Gram-positive bacteria

  • Enteric Gram-negative bacteria exhibit bile resistance and survive

  • Selectivity improves target organism recovery and colony differentiation

This selective pressure enhances accuracy in pathogen detection and enumeration.
