( 2005 ) Naxibacter alkalitolerans gen. nov., sp. nov., a novel member of the family 'Oxalobacteraceae' isolated from China. PMID : 15879247 DOI : 10.1099/ijs.0.63407-0 Abstract >>
A taxonomic study was performed on strain YIM 31775(T), which was isolated from a soil sample collected from Yunnan Province, China. The isolate was chemo-organotrophic, aerobic and Gram-negative. Cells were short rods and motile, with one or more polar flagella. Growth temperature and pH ranged from 4 to 55 degrees C and 6.5 to 12.0, respectively; the optimum growth temperature and pH were 28-37 degrees C and 7.0-9.0, respectively. Q-8 was the predominant respiratory lipoquinone. The major fatty acids were C(16 : 1)omega7c (42.4 %) and C(16 : 0) (28.1 %). The DNA G + C content was 62.4 +/ -0.3 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain YIM 31775(T) should be placed within the family 'Oxalobacteraceae', in which it formed a distinct lineage. Based on the high 16S rRNA gene sequence divergence and phenotypic characteristics, it is proposed that strain YIM 31775(T) should be classified as representing a novel member of the family 'Oxalobacteraceae', for which the name Naxibacter alkalitolerans gen. nov., sp. nov. is proposed. The type strain is YIM 31775(T) (= CCTCC AA 204003(T) = KCTC 12194(T)).

( 2011 ) Revision of the genus Massilia La Scola et al. 2000, with an emended description of the genus and inclusion of all species of the genus Naxibacter as new combinations, and proposal of Massilia consociata sp. nov. PMID : 20656816 DOI : 10.1099/ijs.0.025585-0 Abstract >>
A Gram-stain-negative, rod-shaped, non-spore-forming bacterium originating from a human clinical specimen was studied for its taxonomic position. 16S rRNA gene sequence similarity studies clearly allocated this strain (CCUG 58010(T)) to the class Betaproteobacteria, closely related to members of the genera Massilia and Naxibacter. Naxibacter varians was shown to be the most closely related species on the basis of 16S rRNA gene sequence similarity (97.5 %), followed by Massilia niastensis (96.8 %) and Massilia aerilata (96.4 %). Similarities to all other species of the genera Naxibacter and Massilia were in the range 93.9-96.2 %. Chemotaxonomic data (major ubiquinone: Q-8; major polar lipids: phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol; and major fatty acids: summed feature 3 (C(16 : 1)�s7c and/or iso-C(15 : 0) 2-OH), C(16 : 0), C(18 : 1)�s7c and C(12 : 0), with C(10 : 0) 3-OH as hydroxylated fatty acid) supported the affiliation of the isolate to these genera, which share these chemotaxonomic traits. DNA-DNA hybridization of strain CCUG 58010(T) with the type strain of N. varians CCUG 35299(T) resulted in a relatedness value of 39.2 % (reciprocal, 50 %) and physiological and biochemical tests also allowed phenotypic differentiation of the isolate from the most closely related species. There is currently no justification for a division of the genera Massilia and Naxibacter and for this reason a proposal is made to transfer all species of the genus Naxibacter to the genus Massilia, as Massilia alkalitolerans comb. nov., Massilia varians comb. nov., Massilia haematophila comb. nov. and Massilia suwonensis comb. nov. Strain CCUG 58010(T) represents a novel species, for which the name Massilia consociata sp. nov. is proposed, with the type strain CCUG 58010(T) (= CCM 7792(T)).
