Partner tools


Predictive tools developed in partnership with Sym’Previus are listed below::


Affiliation to the phylogenetic group (I to VII) of Bacillus cereus

This tool uses the panC gene sequence to identify the phylogenetic group of a microbial isolate from the Group Bacillus cereus, according to the classification proposed by Guinebretière et al. (2008). The method consists in comparing the nucleotide sequence(s) of the panC gene with the sequences from a database and calculate the percentage of homology and the statistical significance of the matches.

Conversion of permeability coefficients (MAP optional module)

The units of permeability coefficients for materials used for modified atmosphere preservation (trays, fims and pouches) may vary from one manufacturer to another. This tool allows you to convert from the unit used in the manufacturer’s data sheet to that used in Sym’Previus’ optional MAP (MAP Optimization) bacterial growth simulation module.


Other tools under development will be available on this page soon.
