Hello,
Im not sure if this is appropriate for this forum or should be directed at Silva, but I have found a potential problem with the Silva 132 mothur-formatted taxonomy file. Currently in the file there is the order level taxon Nitrosococcales with family Nitrosococcaceae and genus AqS1. In searching through the literature I have not been able to find the order Nitrosococcales or family Nitrosococcaceae. Additionally the only genus I have found thus far called AqS1 belongs to the order Chromatiales. I have included a reference for this below. Any help or info on this would be much appreciated!
Thanks,
Alexis
