Dear Martina,

      I think that it is more important that the correct ATCC number be
used for your testing.  Names of microorganisms are always changing and
will continue to do so in the future by doing DNA analysis of various
strains and comparing the results.   I think that it is more important that
you have continuity in your testing by using the same strain.  When the
European Pharmacopeia is updated, I would suspect that the name of
Aspergillus niger will be changed to Aspergillus brasiliensis.

Dear Colleagues,



I have one problem concerning test microorganism ATCC 16404 Aspergillus
niger. I ordered it from Microbiologics and we've got an answer that ATCC
16404 was changed name from Aspergillus niger to Aspergillus brasiliensis.
The name was changed because ATCC has determined that this strain belongs
to the species Aspergillus brasiliensis.

According to European Pharmacopoeia micro-organism ATCC 16404 Aspergillus
niger should be used. So, my question is, is more important the ATCC number
or name of microorganism.



Best regards,

Martina BencetiŠ MarijanoviŠ
