| martelella mediterranea gen. nov., sp. nov., a novel alpha-proteobacterium isolated from a subterranean saline lake. | a bacterial strain was isolated from the water of lake martel in mallorca (spain). the isolate, designated macl11(t), was halotolerant and strictly aerobic. the cells were non-motile, non-spore-forming, gram-negative short rods. comparative 16s rrna gene sequence analysis revealed that macl11(t) represents a separate line of descent within the order 'rhizobiales' of the class 'alphaproteobacteria'. strain macl11(t) was most closely related to the genera rhizobium (93.3 % sequence similarity to r ... | 2005 | 15774691 |
| a novel cold-active and alkali-stable β-glucosidase gene isolated from the marine bacterium martelella mediterranea. | a β-glucosidase gene designated gluc3m was cloned through construction of a genomic library of martelella mediterranea 2928. the gluc3m consisted of 2,496 bp and encoded a peptide of 832 amino acids that shared the greatest amino acid similarity (59%) with a β-glucosidase of family 3 glycoside hydrolase from agrobacterium radiobacter k84. the optimum reaction temperature and ph of gluc3m were 45 °c and 8.0, respectively. the k (m) and v (max) for p-nitrophenyl-β-d: -glucopyranoside were 0.18 mg/ ... | 2010 | 20503105 |
| martelella suaedae sp. nov. and martelella limonii sp. nov., isolated from the root of halophytes. | two gram-stain-negative, aerobic and endophytic bacterial strains, designated yc7033t and yc7034t, were isolated from the roots of halophytes (suaeda maritime and limonium tetragonum, respectively) inhabiting tidal flats of the sacheon area, korea. the phylogenetic analyses of 16s rrna gene sequences showed that the two strains were closely related to martelella endophytica yc6887t, martelella mangrovi bm9-1t, martelella radicis bm5-7t and martelella mediterranea dsm 17316t at 97.6-99.1 % simila ... | 2016 | 27393138 |
| martelella radicis sp. nov. and martelella mangrovi sp. nov., isolated from mangrove sediment. | two gram-stain-negative, non-motile, rod-shaped bacterial strains, designated bm5-7(t) and bm9-1(t) were isolated from soil of the root system of a mangrove forest. phylogenetic analysis based on 16s rrna gene sequences showed that the two isolates belong to the genus martelella. the chemotaxonomic characteristics of these isolates included the presence of c19 : 0 cyclo ω8c and c18 : 1ω7c as the major cellular fatty acids and q-10 as the dominant ubiquinone. the genomic dna g+c contents of strai ... | 2014 | 24944336 |
| martelella endophytica sp. nov., an antifungal bacterium associated with a halophyte. | a gram-staining-negative, non-spore-forming endophytic bacterium, designated strain yc6887(t), was isolated from a root sample of a halophyte, rosa rugosa, collected from a tidal flat area of namhae island, located at the southern end of korea. strain yc6887(t) was found to exhibit inhibitory activity against oomycete plant pathogens. the cells were non-motile and aerobic rods. the strain was able to grow at 4-40 °c (optimum 28-30 °c) and at ph 5.0-9.0 (optimum ph 7.0-8.5). strain yc6887(t) was ... | 2013 | 23355694 |
| molecular cloning, purification, and characterization of a novel, acidic, ph-stable endoglucanase from martelella mediterranea. | a novel gene encoding an endoglucanase designated cel5d was cloned from a marine bacterium martelella mediterranea by genomic library. the gene had a 1,113 bp opening reading frame encoding a 371-amino-acid protein with a molecular mass of 40,508 da and containing a putative signal peptide (41 amino acids). cel5d had low similarity (48-51% identity) with other known endoglucanases and consisted of one single catalytic domain, which belonged to the glycosyl hydrolase family 5. the maximum activit ... | 2010 | 20571959 |
