Engon LT100 Broth is primarily used in microbiological testing for the cultivation and maintenance of fastidious microorganisms, particularly in clinical and research laboratories. It supports the growth of bacteria that require enriched nutrient conditions, such as streptococci and other pathogens isolated from human specimens. The broth is often employed in sample transport and preservation, allowing viable microorganism recovery during transit from collection site to lab. It is also utilized in antibiotic susceptibility testing and bacterial enrichment prior to subculturing. Its liquid formulation facilitates inoculation and downstream processing in diagnostic workflows.
