5% Lactose Fermentation Tube

BABIO manufactures high-quality 5% Lactose Fermentation Tube for biochemical identification of Shigella species, especially Shigella sonnei, in microbiology laboratories. The 5% Lactose Fermentation Tube is widely used in clinical diagnostics, food microbiology testing, infectious disease screening, and Enterobacteriaceae identification workflows.

BABIO 5% Lactose Fermentation Tube supports accurate detection of lactose fermentation activity using pH indicator technology. Lactose-positive bacteria such as Escherichia coli and Shigella sonnei produce acid and turn the medium yellow, while lactose-negative strains including Shigella dysenteriae and Shigella flexneri remain blue or blue-green. The enriched 5% lactose formulation improves sensitivity for delayed fermentation detection, especially in modern microbiology culture media and bacterial biochemical identification testing.

This 5% Lactose Fermentation Tube comes in sterile glass ampoules with 20 tubes per box, stable room-temperature storage, and a one-year shelf life. It ensures reliable microbial differentiation, consistent biochemical reaction results, and strong performance in laboratory quality control and pathogen identification systems.
