  • WDCM 00079

Negative reaction:
No mauve/purple/violet colour

CRM-CPE.00007MH is suitable for process control for anaerobic spores and cells analysis.

For the non-selective reference medium, it is best to use blood agar instead of TSA.

For performance testing of Acis phosphatase reagent, Clostridium bifermentans WDCM 00079 is not available in the Biosisto collection. If you need this strain, please get in touch with us.

Biosisto - Quality in Control

Microbiological laboratories should be able to receive reliable analysis without much overhead. A microbiological analyst must be able to focus on the primary activities, for example analysis of the sample material. Quality control should support the analyst in a logical and simple manner. By using modern information technology, process control and quality assurance are designed smarter and more effective.
