Thirty six Gram-positive, rod-shaped, non-spore-forming, non-motile bacterial strains were isolated from the non-salted pickle solution used in producing sunki products, a traditional Japanese pickle. The novel strains were discriminated and separated into four groups by amplified fragment length polymorphism profiling, and by analysis based on gene sequences. The strains were classified into four species groups belonging to the species group, which consists of , , , , and . The phenotypic and genotypic features of the four groups demonstrated that they represented four novel species, for which the names sp. nov. (type strain YIT 11168=NRIC 0741=JCM 15041=DSM 19906), sp. nov. (type strain YIT 11163=NRIC 0742=JCM 15040=DSM 19908), sp. nov. (type strain YIT 11204=NRIC 0743=JCM 15042=DSM 19907) and sp. nov. (type strain YIT 11161=NRIC 0744=JCM 15039=DSM 19904) are proposed.
