Description

Double Lactose Bile Ferment Broth: Enhanced Medium for Coliform Detection

Product Overview
The Double Lactose Bile Ferment Broth is designed for effective coliform bacteria detection, especially Escherichia coli. Each package includes 20 sealed 10ml tubes, ensuring leak-proof storage and contamination prevention. This broth is crucial for microbiological analysis in water testing, food safety, and clinical diagnostics.

Key Features

• Composition
  Enriched with peptones for essential nutrients, this broth uses lactose as a fermentable carbohydrate and bile salts to inhibit Gram-positive bacteria. Bromocresol purple serves as a pH indicator, signaling fermentation through color change.
• Sensitivity Testing
  For quality control, inoculate specified strains and incubate at 36±1°C for 24±2 hours. Expected results include:

  Quality Control Strain	Strain Number	Inoculum (CFU)	Growth Condition	Result
  Escherichia coli	ATCC 25922	10-100	+++	Acid and gas production
  Salmonella typhimurium	ATCC 14028	10-100	+++	Acid production, no gas
  Enterococcus faecalis	ATCC 29212	1000-5000	–	Inhibited
  Enterobacter cloacae	ATCC 43864	10-100	+++	Acid and gas production
  Enterobacter aerogenes	ATCC 23355	10-100	+++	Acid and gas production
  Enterobacter aerogenes	ATCC 13048	10-100	+++	Acid and gas production
