Investigation of the microbial diversity of Ntoba Mbodi, an African food made from the alkaline fermentation of cassava leaves, revealed the presence of a Gram-positive, catalase-positive, aerobic, motile and rod-shaped endospore-forming bacterium (NM73) with unusual phenotypic and genotypic characteristics. The analysis of the 16S rRNA gene sequence revealed that the isolate was most closely related to Lysinibacillus meyeri WS 4626T (98.93 %), Lysinibacillus xylanilyticus XDB9T (96.95 %) and Lysinibacillus odysseyi 34hs-1T (96.94 %). The DNA–DNA relatedness of the isolate with L. meyeri LMG 26643T, L. xylanilyticus DSM 23493T and L. odysseyi DSM 18869T was 41 %, 16 % and 15 %, respectively. The internal transcribed spacer-PCR profile of the isolate was different from those of closely related bacteria. The cell-wall peptidoglycan type was A4α, l-Lys-d-Asp and the major fatty acids were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C17 : 0 and iso-C17 : 1ω10c. The polar lipids included phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphoaminolipid, aminolipid, two phospholipids and two unknown lipids. The predominant menaquinones were MK-7 and MK-6. Ribose was the only whole-cell sugar detected. The DNA G+C content was 38 mol%. Based on the results of the phenotypic and genotypic characterization, it was concluded that the isolate represents a novel species of the genus Lysinibacillus, for which the name of Lysinibacillus louembei sp. nov. is proposed. NM73T ( = DSM 25583T = LMG 26837T) represents the type strain.

The 16S Rrna Gene

A novel, non-pigmented, rod-shaped, Gram-negative strain was isolated from mesotrophic lake water in Zealand, Denmark. Phylogenetic analysis of the 16S rRNA gene sequence of the bacterium, designated strain 389T, indicated that the strain belonged to the genus Vogesella and formed a monophyletic group with Vogesella perlucida DS-28T (99.1 % nucleotide similarity); it was less related to Vogesella indigofera ATCC 19706T (96.9 % similarity) and Vogesella lacus LMG 24504T (96.8 % similarity). Hybridization of DNA from strain 389T and V. perlucida demonstrated a reassociation of 50.6±9.6 %. The DNA G+C content of strain 389T was 61.2 mol%. The fatty acid profile of the strain differed from those of the other strains representing the genus Vogesella by a high content of C16 : 1 ω7c and/or iso-C15 : 0 2-OH (71.6 %) and a lower content of C16 : 0. Strain 389T was capable of degrading peptidoglycan and had chitinase and lysozyme activities, possibly associated with the degradation of peptidoglycan, and had capacity for degradation of several other polymer compounds. Based on phenotypic and genotypic characteristics, strain 389T represents a novel species, for which we propose the name Vogesella mureinivorans sp. nov. The type strain is 389T (=DSM 21247T =LMG 25302T).

A novel actinomycete, strain ST1-08T, was isolated from the stem of Stemona sp. in Thailand. The taxonomic position of this isolate was determined by using a polyphasic approach. Strain ST1-08T contained meso-diaminopimelic acid in the cell-wall peptidoglycan, and arabinose and galactose as diagnostic sugars of the whole-cell hydrolysate, which are typical properties of members of the genus Amycolatopsis. Strain ST1-08T grew at 15–40 °C, pH 6–9 and on 5 % (w/v) NaCl. Gelatin liquefaction, starch hydrolysis and skimmed milk peptonization were positive. The strain utilized l-arabinose, d-glucose, glycerol, myo-inositol, d-mannitol and l-rhamnose. The predominant menaquinone was MK-9(H4) and the major cellular fatty acids were iso-C16 : 0 and iso-C15 : 0.The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyl-phosphatidylethanolamine, phosphatidylinositol and phosphatidylglycerol. The 16S rRNA gene sequence analysis revealed that the strain was closely related to Amycolatopsis pretoriensis JCM 12673T (98.99 %) and Amycolatopsis lexingtonensis JCM 12672T (98.87 %). The DNA G+C content of strain ST1-08T was 71.2 mol%. The DNA–DNA relatedness values among strain ST1-08T, A. pretoriensis JCM 12673T and A. lexingtonensis JCM 12672T were lower than 70 %, the cut-off level for assigning strains to the same species. On the basis of phenotypic and genotypic characteristics, strain ST1-08T represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis stemonae is proposed. The type strain is ST1-08T( = JCM 30050T = PCU 339T = TISTR 2278T).

A novel nitrate-reducing bacterium, CPW406T, was isolated from the sediment of a shallow, freshwater lake. The strain was a Gram-negative, non-motile, non-spore-forming rod, which formed yellow-pigmented colonies on nutrient agar and contained a polyamine pattern with sym-homospermidine as the major compound, MK-6 as the predominant menaquinone, 15 : 0 iso and 17 : 0 iso 3-OH as the major fatty acids and phosphatidylethanolamine and several unknown lipids in the polar lipid profile. The 16S rRNA gene sequence of strain CPW406T was found to be most similar to that of the type strain of Chryseobacterium defluvii (DSM 14219T; 97·9 % similarity). However, DNA–DNA relatedness data and its phenotypic properties showed that strain CPW406T could be distinguished from all known Chryseobacterium species and thus represented a novel species, for which the name Chryseobacterium daecheongense sp. nov. is proposed; the type strain is CPW406T (=DSM 15235T=KCTC 12088T).

An actinomycete, designated strain E71T, was isolated from the stem of Sambucus adnata Wall, a Chinese medicinal plant, and subjected to a polyphasic taxonomic study. Phylogenetic analyses based on the 16S rRNA gene sequence showed that the organism was a member of the genus Glycomyces, and formed a distinct phyletic line distantly related to recognized species of the genus Glycomyces. Morphological and chemotaxonomic data supported the affiliation of strain E71T to the genus Glycomyces. A number of physiological properties and a unique menaquinone profile allowed differentiation of the strain from related Glycomyces species. It is therefore proposed that strain E71T represents a novel species of the genus Glycomyces, for which the name Glycomyces sambucus sp. nov. is proposed. The type strain is E71T (=CGMCC 4.3147T=DSM 45047T).

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).

A Gram-negative, non-spore-forming, cream-coloured bacterial strain, UM2T, was isolated from an open hexachlorocyclohexane (HCH) dump site at Ummari village in Lucknow, India. Data generated from a polyphasic approach including phenotypic, genotypic and chemotaxonomic analyses confirmed that strain UM2T belonged to the genus Sphingomonas. The highest similarity found to the 16S rRNA gene sequence of strain UM2T was 99.4 %, with Sphingomonas wittichii DSM 6014T, whereas the DNA–DNA relatedness value between these strains was 31 %, indicating that they represent separate species. The DNA G+C content of UM2T was 66.9 mol%. The respiratory pigment ubiquinone Q-10 was present. The predominant fatty acids were summed feature 8 (C18 : 1 ω6c and/or C18 : 1 ω7c; 32.9 %), C19 : 0 cyclo ω8c (15.5 %) and C16 : 0 (12.1 %). The major polar lipids were phosphatidylcholine, phosphatidylglycerol and phosphatidyldimethylethanolamine. sym-Homospermidine was the major polyamine observed. On the basis of the data reported, it was concluded that UM2T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas histidinilytica sp. nov. is proposed. The type strain is UM2T (=MTCC 9473T =CCM 7545T).
