General description
Application
Features and Benefits
- GranuCult® offers superior granulated culture media
- Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment
- Excellent wettability, solubility, and free-flowing properties
- Convenient, with minimal component separation and clumping, even under warm or humid conditions
- High batch-to-batch reproducibility
- Prolonged shelf life of up to five years
- High number of test strains exceeding all regulatory demands
- Granulation technology allows many supplements to be included, with no need to add these separately

Recovery on test medium (Mucor racemus ATCC 42647 (WDCM00181)): ≥ 50 %
Growth (Escherichia coli ATCC 8739 (WDCM 00012)): no growth
Growth Escherichia coliATCC 25922 (WDCM 00013): no growth
Growth (Bacillus subtilis ATCC 6633 (WDCM 00003)): no growth
Incubation: 5 days at 25 ± 1 °C
A recovery rate of 50 % is equivalent to a productivity value of 0.5.
The indicated colony counts result from the sum of a triple determination.
Reference media: SABOURAUD dextrose agar
