KCTC 13219 (=b04i-3), isolated from Pu'er tea by Dr. Kyung Sook Bae (2005, unpublished result), had been listed as a type strain of “Bacillus nitroreducens” from the KCTC web site until recently. However, the original submitter did not propose it as s novel species. There were two records in the NCBI for this strain before the genome sequencing of KCTC 13219:

1. 16S ribosomal gene sequence (EU391158.1)
2. information in the taxonomy browser (512421)

The authors used to designate it just as b04i-3T or B04I-3T without KCTC number from the web site, probably because the information was registered to NCBI before the strain got an official KCTC number. A peroxide-degrading Bacillus isolate (strain PLC9 =KACC 91464P) was named after it based on 100% 16S rRNA sequence similarity to KCTC 13219 (New bacteria Bacillus nitroreducens PLC9 with hydrogen peroxide-degrading activity with high survival rate in hydrogen peroxide. Appl Biochem Biotechnol 2013, 169:701-711. PMID: 23271626).

There is no relationship between KCTC 13219 (=b04i-3) and Bacillus sp. B04I-3T, a patented microorganism in Japan. It would be inappropriate that the Japanese patent information web site refers to the same NCBI taxonomy page (link) as KCTC 13219 does.

The following neighbor-joining phylogenetic tree, based on 16S rRNA gene sequences, suggests that KCTC 13219 should be classified into the genus Lysinibacillus.
