Product Description
Litmus Lactose Bile Salt Agar (LLBSA) is a specialized microbiological medium designed for the selective isolation and differentiation of enteric bacteria. This agar contains bile salts to inhibit gram-positive bacteria, lactose as a fermentable carbohydrate, and litmus as a pH indicator. The medium turns red in acidic conditions (fermentation) and blue in alkaline conditions, aiding in the identification of lactose-fermenting and non-fermenting bacteria.
Ideal for research labs, educational institutions, and clinical microbiology, LLBSA is widely used for detecting E. coli and other coliforms. The high-quality formulation from Himedia ensures consistent performance, making it a reliable choice for routine microbiological testing.
When preparing LLBSA, follow standard protocols for sterilization and pouring to achieve optimal results. Store the powder in a cool, dry place away from direct sunlight to maintain its efficacy.

The powder has a shelf life of 3 years when stored properly in a cool, dry place.
Can LLBSA be used for environmental sampling?
Yes, it is suitable for testing water, food, and environmental samples for coliform contamination.
How does litmus help in bacterial identification?
Litmus acts as a pH indicator. Lactose fermentation produces acid, turning the medium red, while non-fermenters keep it blue.
Is LLBSA selective for gram-negative bacteria?
Yes, the bile salts inhibit most gram-positive bacteria, allowing selective growth of gram-negative enteric pathogens.
