In the early 1980s, a facultatively anaerobic, non-motile, short rod, designated 202T, was isolated from a chicken crop and identified as a homofermentative lactic acid bacterium. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain was affiliated with the genus Lactobacillus, clustering within the Lactobacillus acidophilus–delbrueckii group. In this analysis, strain 202T appeared to be most closely related to the type strains of Lactobacillus intestinalis and Lactobacillus amylolyticus, with gene sequence similarities of 96.1 and 96.2 %, respectively. Strain 202T was found to differ from these two species, however, when investigated by multilocus sequence analysis, and it also differed in terms of some of its metabolic properties. On the basis of these observations, strain 202T is considered to represent a novel species in the genus Lactobacillus, for which the name Lactobacillus gigeriorum sp. nov. is proposed; the type strain is 202T ( = CRBIP 24.85T = DSM 23908T).

An extremely haloalkaliphilic archaeon, strain AD2T, was isolated from Aiding salt lake in Xin-Jiang, China. Strain AD2T required at least 12 % NaCl for growth. MgCl2 was not required. The isolate was able to grow over a pH range of 8.0–10.0 and temperature range of 20–55 °C, with optimal growth at pH 8.7–9.2 and 44–47 °C. The major polar lipids of strain AD2T were phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester; glycolipids were not detected. Analysis of its 16S rRNA gene sequence indicated that strain AD2T was phylogenetically related to members of the genus Natronorubrum, with sequence similarities to the type strains of Natronorubrum bangense, Natronorubrum tibetense and Natronorubrum aibiense of 97.1, 95.9 and 96.1 %, respectively. The G+C content of its DNA was 60.9 mol% (T m). Levels of DNA–DNA relatedness between strain AD2T and the type strains of Nrr. bangense, Nrr. tibetense and Nrr. aibiense were 49, 38 and 41 %, respectively. It was concluded that strain AD2T represents a novel species of the genus Natronorubrum, for which the name Natronorubrum sulfidifaciens sp. nov. is proposed. The type strain is AD2T (=CGMCC 1.6307T=JCM 14089T).

Three Gram-negative, anaerobic, rod-shaped bacteria (strains CB40, CB41 and CB42T) were isolated from human faeces. Based on phylogenetic analysis and specific phenotypic characteristics, these strains were included in the genus Bacteroides, and 16S rRNA gene sequence analysis indicated that these strains represented a novel species. The strains were most closely related to the type strains of Bacteroides barnesiae and Bacteroides salanitronis, with sequence similarities of 93.4 and 89.8 %, respectively. The G+C content of strain CB42T is 44.7 mol%. Major fatty acids were anteiso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH and C18 : 1 ω9c. On the basis of the data presented, a novel Bacteroides species, Bacteroides coprophilus sp. nov., is proposed, with CB42T (=JCM 13818T=DSM 18228T) as the type strain.

A novel strain, designated KP01T, belonging to the class Sphingobacteria (phylum Bacteroidetes) was isolated from soil in South Korea and was characterized taxonomically using a polyphasic approach. The strain was found to comprise Gram-negative, aerobic, non-motile, non-spore-forming rods. A phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Chitinophaga but was clearly separated from established Chitinophaga species. The 16S rRNA gene sequence similarities between KP01T and type strains of established Chitinophaga species ranged from 90.3 to 95.7 %. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; major fatty acids, iso-C15 : 0 and C16 : 1 ω5c; major hydroxy fatty acid, C17 : 0 iso 3-OH) supported the affiliation of strain KP01T with the genus Chitinophaga. Therefore strain KP01T represents a novel species, for which the name Chitinophaga terrae sp. nov. is proposed. The type strain is KP01T (=KCTC 12836T =LMG 24015T).

The genomic DNA G+C content was 36.5 mol% (HPLC). 16S rRNA gene sequence phylogenetic analysis revealed that strain BZ42T was a member of the genus Pedobacter, family Sphingobacteriaceae, and 16S rRNA gene sequence similarities between strain BZ42T and the type strains of species of the genus Pedobacter with validly published names were 90.4–93.2 %. On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain BZ42T was considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter bauzanensis sp. nov. is proposed.

The isolate grew optimally at 20–30 °C and pH 7.3–7.8. Comparative analysis of the 16S rRNA gene sequence showed that isolate XJ259T belonged phylogenetically to the genus Paenibacillus, and was most closely related to Paenibacillus xinjiangensis B538T (with 96.6 % sequence similarity), Paenibacillus glycanilyticus DS-1T (96.3 %) and Paenibacillus castaneae Ch-32T (96.1 %), sharing less than 96.0 % sequence similarity with all other members of the genus Paenibacillus. Chemotaxonomic analysis revealing menaquinone-7 (MK-7) as the major isoprenoid quinone, diphosphatidylglycerol, phosphatidylethanolamine and two unknown phosphoglycolipids as the major cellular polar lipids, a DNA G+C content of 47.0 mol%, and anteiso-C15 : 0 and C16 : 0 as the major fatty acids supported affiliation of the new isolate to the genus Paenibacillus. Based on these data, isolate XJ259T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus algorifonticola sp. nov. is proposed. The type strain is XJ259T ( = CGMCC 1.10223T  = JCM 16598T).

A novel halophilic archaeon, strain EJ-32T, was isolated from water from Lake Ejinor in Inner Mongolia, China. The taxonomy of strain EJ-32T was studied by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities, strain EJ-32T was shown to be phylogenetically related to Halorubrum coriense (97.9 %), Halorubrum trapanicum (97.9 %), Halorubrum sodomense (97.8 %), Halorubrum tebenquichense (97.8 %), Halorubrum xinjiangense (97.6 %), Halorubrum terrestre (97.4 %), Halorubrum distributum (97.1 %) and Halorubrum saccharovorum (96.4 %). Strain EJ-32T was found to be neutrophilic, non-motile and Gram-negative. It grew in medium containing saturation concentrations of NaCl and did not require magnesium for optimal growth. The G+C content of the DNA is 64.0 mol%. Values for DNA–DNA hybridization with respect to phylogenetically related Halorubrum species were ≤49 %, indicating that EJ-32T constitutes a different genospecies. The data show that strain EJ-32T represents a novel species of the genus Halorubrum, for which the name Halorubrum ejinorense sp. nov. is proposed. The type strain is EJ-32T (=CECT 7194T=CGMCC 1.6782T=JCM 14265T).
