( 2015 ) Revision of the taxonomic status of type strains of Mesorhizobium loti and reclassification of strain USDA 3471T as the type strain of Mesorhizobiumerdmanii sp. nov. and ATCC 33669T as the type strain of Mesorhizobiumjarvisii sp. nov. PMID : 25736411 DOI : 10.1099/ijs.0.000164 DOI : 10.1099/ijs.0.000164 Abstract >>
The species Mesorhizobim loti was isolated from nodules of Lotus corniculatus and its type strain deposited in several collections. Some of these type strains, such as those deposited in the USDA and ATCC collections before 1990, are not coincident with the original strain, NZP 2213T, deposited in the NZP culture collection. The analysis of the 16S rRNA gene showed that strains USDA 3471T and ATCC 33669T formed independent branches from that occupied by Mesorhizobium loti NZP 2213T and related to those occupied by Mesorhizobium opportunistum WSM2075T and Mesorhizobium huakuii IFO 15243T, respectively, with 99.9 % similarity in both cases. However, the analysis of concatenated recA, atpD and glnII genes with similarities lower than 96, 98 and 94 %, respectively, between strains USDA 3471T and M. opportunistum WSM2075T and between strains ATCC 33669T and M. huakuii IFO 15243T, indicated that the strains USDA 3471T and ATCC 33669T represent different species of the genus Mesorhizobium. These results were confirmed by DNA-DNA hybridization experiments and phenotypic characterization. Therefore, the two strains were reclassified as representatives of the two species Mesorhizobium erdmanii sp. nov. (type strain USDA 3471T = CECT 8631T = LMG 17826t2T) and Mesorhizobium jarvisii sp. nov. (type strain ATCC 33669T = CECT 8632T = LMG 28313T).

( 2015 ) Oricola cellulosilytica gen. nov., sp. nov., a cellulose-degrading bacterium of the family Phyllobacteriaceae isolated from surface seashore water, and emended descriptions of Mesorhizobium loti and Phyllobacterium myrsinacearum. PMID : 25566955 DOI : 10.1007/s10482-014-0370-6 Abstract >>
A Gram-stain negative, strictly aerobic, rod-shaped, non-spore-forming, motile cellulolytic bacterium, designated strain CC-AMH-0(T), was isolated from surface seashore water of Hualien, Taiwan and subjected to polyphasic taxonomy. Strain CC-AMH-0(T) exhibited enzymatic saccharification of cellulose and active growth particularly during log-phase under nutrient-limited conditions, whereas enhanced saccharification was found in the declining growth phase under copiotrophic conditions. The novel strain shared high pairwise 16S rRNA gene sequence similarities to Mesorhizobium loti USDA 3471(T) (96.2 %), Phyllobacterium myrsinacearum IAM 13584(T) (95.9 %), Hoeflea marina LMG 128(T) (94.0 %) and other Phyllobacteriaceae members. However, phylogenetic analyses based on 16S rRNA, atpD and recA gene sequences clearly distinguished strain CC-AMH-0(T) from other representatives of related genera. In addition, strain CC-AMH-0(T) was distinguished from the above mentioned species by significantly lacking phosphatidylcholine besides accommodating major amounts of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmonomethylethanolamine and sulfoquinovosyldiacylglycerol; moderate amounts of phosphatidylethanolamine and trace amounts of an unidentified phospholipid, an unidentified aminolipid and an unidentified phosphoglycolipid. Strain CC-AMH-0(T) possessed C18:1 �s7c and/or C18:1 �s6c (summed feature 8) as predominant fatty acids, 63.3 mol% DNA G+C content and ubiquinone-10 (Q-10) as the sole respiratory quinone. On the basis of polyphasic taxonomic evidences, strain CC-AMH-0(T) is proposed to represent a novel genus and species of the family Phyllobacteriaceae, for which the name Oricola cellulosilytica gen. nov., sp. nov. is proposed. The type strain of the type species is CC-AMH-0(T) (=JCM 19534(T) =BCRC 80694(T)). Emended descriptions of M. loti and P. myrsinacearum are also proposed.
