Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Test conditions

Details on test conditions:
Method/ Guideline followed (experimental/ calculated) : Information not available
Test type : The assay determined the percentage of strains of bacteria sensitive or resistant to Cd or Zn able to grow on various organic substrates
Species/ Strain : Cd sensitive and resistant bacteria and Zn sensitive and resistant bacteria
Test organisms : Cd sensitive and resistant bacteria and Zn sensitive and resistant bacteria from a sandy soil
Test Conditions : Information not available
End-point : Percentage of strains able to grow on the substrate
Test design (number of replicates, individuals per replicate, concentrations (static/ semistatic)) :
    - Number of strains of bacteria Cd-sensitive tested: 93
- Number of strains of bacteria Cd-resistant tested: 64
-  Number of strains of bacteria Zn-sensitive tested: 84

Results and discussion

Reported statistics and error estimates:
no data

Any other information on results incl. tables

Strains able to grow on the substrate 

  Cd-sensitive  Cd-resistant  Zn-sensitive  Zn-resistant
 Salicylic acid  16 %  16 %  17 %  5 %
 Mean of 23 various substrates  8.7 %  4.3 %  9.4 %  2.6 %


Applicant's summary and conclusion

Conclusions:
It appears that Salicylic acid can be considered as a "good" organic substrate for bacteria.
Indeed, the percentage of bacteria able to grow on this substrate is higher than the mean obtained for the 23 substrates.
