Osmoregulation in symbiosis-independent mutants of Bdellovibrio bacteriovorus.
نویسندگان
چکیده
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.

Symbiosis-independent and symbiosis-incompetent mutants of Bdellovibrio bacteriovorus 109J.
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 aga...
متن کاملRole of Type IV Pili in Predation by Bdellovibrio bacteriovorus
Bdellovibrio bacteriovorus, as an obligate predator of Gram-negative bacteria, requires contact with the surface of a prey cell in order to initiate the life cycle. After attachment, the predator penetrates the prey cell outer membrane and enters the periplasmic space. Attack phase cells of B. bacteriovorus have polar Type IV pili that are required for predation. In other bacteria, these pili h...

Isolation and characterization of temperature-sensitive mutants of host-dependent Bdellovibrio bacteriovorus 109D.
A variety of temperature-sensitive mutants of host-dependent Bdellovibrio bacteriovorus 109D were selected after ethyl methane sulfonate mutagenesis. Mutants that demonstrated plaque-forming ability reversion frequencies of 10(-8) to 10(-9) were chosen for further study. Representatives of these mutants were then characterized by phase-contrast and electron microscopy, temperature-shifted one-s...
متن کاملIsolation of predation-deficient mutants of Bdellovibrio bacteriovorus by using transposon mutagenesis.
The availability of the complete genome sequence of Bdellovibrio bacteriovorus provides an opportunity for investigating genes that play a significant role in predation. Using two independently derived facultatively predatory Bdellovibrio strains, we have designed a method to cultivate and screen transposon insertion mutants in 96-well microtiter dishes. Transposon insertion mutants were produc...
