SIM Medium - Sulfide Indole Motility Medium
SIM Medium, also known as Sulfide Indole Motility Medium, is a semisolid dehydrated culture medium used by trained laboratory personnel for the determination of sulfide production, indole formation, and motility in Enterobacteriaceae testing workflows.
This medium is commonly used in microbiology, food testing, water and environmental testing, quality control, teaching, research, and industrial laboratory settings where laboratories require a prepared medium for differential biochemical observation.
Designed for Microbiology Laboratory Workflows
- Sulfide production observation
- Indole formation testing
- Motility observation in semisolid medium
- Enterobacteriaceae screening workflows
- Food, water, environmental, teaching, research, and QC labs
Why Choose SIM Medium?
- Three-in-one differential medium: Supports sulfide, indole, and motility observations in one semisolid medium.
- Semisolid formulation: The low agar concentration allows motility to be observed by growth movement away from the original inoculation line.
- Hydrogen sulfide detection: The formulation includes ferrous ammonium citrate and sodium thiosulfate for sulfide production observation.
- Indole detection workflow: Casein peptone supplies tryptophan, supporting indole formation observation when used with the appropriate reagent and approved lab procedure.
- Multiple package sizes: Available in 500 g, 2 kg, and 10 kg sizes to match routine lab, institutional, and higher-volume usage.
- Canadian purchasing support: Supplied by Cambridge Environmental Products with CAD pricing and support for Canadian laboratory buyers.

Technical Notes for Laboratory Buyers
SIM Medium is a semisolid medium. Motility can be observed by growth movement away from the original stab line, while non-motile organisms typically remain closer to the inoculation line. Sulfide production is indicated by the formation of a black precipitate, and indole observation is performed using the appropriate reagent according to the laboratory’s approved procedure.
This product is intended for use by trained laboratory personnel following approved microbiology procedures, facility safety requirements, and applicable quality control practices. Always refer to the manufacturer literature, internal SOPs, and required safety documentation before use.
Canadian Lab Supply Support
Cambridge Environmental Products supplies SIM Medium to Canadian laboratories with CAD pricing, Canadian purchasing support, and package size options for routine, institutional, and higher-volume microbiology workflows.
