I Haven't a clue; Mucilaginibacter gossypii sp. nov. and Mucilaginibacter gossypiicol I see cotton and it makes me shudder. Anyway, does this make sense to anyone and could/does it apply to cotton as in clothes?
Mucilaginibacter gossypii sp. nov. and Mucilaginibacter gossypiicola sp. nov., plant-growth promoting bacteria isolated from cotton rhizosphere soils [NEW TAXA: Bacteroidetes]
Sundaram, S.
Two isolates from the rhizosphere soil of cotton designated Gh-67T and Gh-48T which produced a large amount of extracellular polysaccharide and possessed plant-growth promoting traits were characterized both phenotypically and genotypically. The strains were Gram-negative and cells were non-motile rods that grew optimally at 28 °C and grew between pH 4 and 7. The 16S rRNA gene sequence analysis of the strains Gh-67T and Gh-48T placed them under the genus Mucilaginibacter with the pairwise sequence similarity between them and type strains of related genera ranging from 93.9 to 98.2%. The major fatty acids contained iso-C15 : 0, C16 : 0 and summed feature 3 (C16 : 17c and/or iso-C15 : 0 2-OH). The strains contained MK-7 as the major isoprenoid quinone. The DNA G+C content of strains Gh-67T and Gh-48T are 46.7 mol% and 44.2 mol% respectively. The low DNA-DNA hybridization value (18%) and a number of phenotypic differences between strains Gh-48T and Gh-67T indicated that they represent two separate species. Results of phenotypic, phylogenetic and genotypic analysis revealed that the strains were separated from the species of Mucilaginibacter so far described. Therefore, strains Gh-67T and Gh-48T represent novel species of Mucilaginibacter, for which we propose the name as Mucilaginibacter gossypii sp. nov. and Mucilaginibacter gossypiicola sp. nov. respectively. The type strain is Gh-67T (=NCIMB 14470T = KCTC 22380T) for Mucilaginibacter gossypii sp. nov. and Gh-48T (=NCIMB 14471T = KCTC 22379T) for Mucilaginibacter gossypiicola sp. nov.
Vogesella mureinivorans sp. nov., a peptidoglycan-degrading bacterium from lake water [NEW TAXA: Proteobacteria]
Friday, November 27, 2009, 10:01:06 AM | Jorgensen, N. O. G., Brandt, K. K., Nybroe, O., Hansen, M.
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 Vogesella genus and formed a monophyletic group with V. perlucida DS-28T (99.1 % nucleotide similarity); it was less related to V. indigofera ATCC 19706T (96.9 % similarity) and V. lacus (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%. Fatty acid profile of the strain differed from the other Vogesella strains by a high content of C16:17c + C15:0 iso 2OH (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 new species for which we propose the name Vogesella mureinivorans sp. nov.. The type strain is 389T (= DSM 21247T = LMG 25302T IJSEM Publish Ahead of Print
