| bacterial communities constructed in artificial consortia of bacteria and chlorella vulgaris. | we established artificial consortia of bacteria inoculated from soil and a green alga, chlorella vulgaris nies-227. the bacteria and the alga were mixed in a tube or partitioned in a dialysing culture vessel, and the bacterial composition was examined after cultivation. the community of bacteria formed in the consortia included those phylogenetically closely related to the genera phenylobacterium, brevundimonas, phyllobacterium, afipia, sphingomonas, sandaracinobacter, ramlibacter, ralstonia, ce ... | 2010 | 21576850 |
| The cyst-dividing bacterium Ramlibacter tataouinensis TTB310 genome reveals a well-stocked toolbox for adaptation to a desert environment. | Ramlibacter tataouinensis TTB310(T) (strain TTB310), a betaproteobacterium isolated from a semi-arid region of South Tunisia (Tataouine), is characterized by the presence of both spherical and rod-shaped cells in pure culture. Cell division of strain TTB310 occurs by the binary fission of spherical "cyst-like" cells ("cyst-cyst" division). The rod-shaped cells formed at the periphery of a colony (consisting mainly of cysts) are highly motile and colonize a new environment, where they form a new ... | 2011 | 21912644 |
| search for microbial signatures within human and microbial calcifications using soft x-ray spectromicroscopy. | the origin of advanced arterial and renal calcification remains poorly understood. self-replicating, calcifying entities have been detected and isolated from calcified human tissues, including blood vessels and kidney stones, and are referred to as nanobacteria. however, the microbiologic nature of putative nanobacteria continues to be debated, in part because of the difficulty in discriminating biomineralized microbes from minerals nucleated on anything else (eg, macromolecules, cell membranes) ... | 2006 | 17169258 |
| a morphological transition in the pleomorphic bacterium ramlibacter tataouinensis ttb310. | we provide microscopic evidence that motile rod-shaped forms of ramlibacter tataouinensis ttb310 are formed from dividing cyst-like cells. careful estimation of the size of the two morphotypes was conducted using optical and transmission electron microscopy (tem). the cyst-like cell was shown to be a sphere with a diameter dc=850 nm. the rod-shaped form was a round-ended cylinder with length lr=2.91 microm and diameter dr=239 nm. the membrane area of the two morphotypes was the same. however, th ... | 2005 | 16112847 |
| ramlibacter tataouinensis gen. nov., sp. nov., and ramlibacter henchirensis sp. nov., cyst-producing bacteria isolated from subdesert soil in tunisia. | ramlibacter gen. nov. is proposed for two aerobic, chemo-organotrophic, cyst-producing soil bacterial strains. these bacteria are gram-negative, non-flagellated rods or cysts, isolated from subdesert soil in tataouine, tunisia. phylogenetic analyses of the rrs sequences of the two strains showed that they do not constitute a robust clade at the genus level with any previously described bacteria and that they are a deep branch of a clade also grouping the genera acidovorax and hydrogenophaga with ... | 2003 | 12710631 |
