Symbiosis-independent and symbiosis-incompetent mutants of Bdellovibrio bacteriovorus 109J.

چکیده
Symbiosis-independent (Sin) mutants were isolated from the symbiosis-dependent and symbiosis-competent (Sdcomp+) Bdellovibrio bacteriovorus 109J. Independently isolated Sin mutants were examined for their symbiosis competence and most were found to be comp+. Bdellovibrios comp- were selected from the Sincomp+ mutants. The Sincomp+ bdellovibrios are always at a selective disadvantage, either against Sincomp- bdellovibrios (in organic medium) or against Sdcomp+ bdellovibrios (in buffer with Escherichia coli cells).

Osmoregulation in symbiosis-independent mutants of Bdellovibrio bacteriovorus.
Bdellovibrios capable of axenic growth grow in a cell-free medium at a rate considerably lower than that attainable in a two-membered culture with Escherichia coli. The axenic growth rate may be improved either by adjustment of the osmosity of the medium or by the addition of low concentrations of spermine.
متن کاملRespiration of Bdellovibrio bacteriovorus strain 109J and its energy substrates for intraperiplasmic growth.
Measurements of oxidation rates, respiratory quotients (RQ), and release of (14)CO(2) from uniformly labeled substrates showed that glutamate, alpha-ketoglutarate, and synthetic and natural amino acid mixtures are oxidized by suspensions of Bdellovibrio bacteriovorus strain 109J. The oxidation of these substrates largely suppress the endogenous respiration of the Bdellovibrio cells and may or m...
متن کاملIdentification and differential production of ubiquinone-8 in the bacterial predator Bdellovibrio bacteriovorus.
Bdellovibrio bacteriovorus 109J, a predatory bacterium with potential as a bacterial control agent, can exist in several lifestyles that differ both in predatory capacity and color. We determined that levels of ubiquinone-8 contribute to the distinctive but variable yellow color of different types of Bdellovibrio cells. Steady-state ubiquinone-8 concentrations did not differ markedly between co...
متن کاملMutation Detection with Next-Generation Resequencing through a Mediator Genome
The affordability of next generation sequencing (NGS) is transforming the field of mutation analysis in bacteria. The genetic basis for phenotype alteration can be identified directly by sequencing the entire genome of the mutant and comparing it to the wild-type (WT) genome, thus identifying acquired mutations. A major limitation for this approach is the need for an a-priori sequenced referenc...
متن کاملCharacterizing the flagellar filament and the role of motility in bacterial prey-penetration by Bdellovibrio bacteriovorus
The predatory bacterium Bdellovibrio bacteriovorus swims rapidly by rotation of a single, polar flagellum comprised of a helical filament of flagellin monomers, contained within a membrane sheath and powered by a basal motor complex. Bdellovibrio collides with, enters and replicates within bacterial prey, a process previously suggested to firstly require flagellar motility and then flagellar sh...
