Identification 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 کاملAnkyrin-mediated self-protection during cell invasion by the bacterial predator Bdellovibrio bacteriovorus
Predatory Bdellovibrio bacteriovorus are natural antimicrobial organisms, killing other bacteria by whole-cell invasion. Self-protection against prey-metabolizing enzymes is important for the evolution of predation. Initial prey entry involves the predator's peptidoglycan DD-endopeptidases, which decrosslink cell walls and prevent wasteful entry by a second predator. Here we identify and charac...
متن کاملIsolation of a bacteriophage for Bdellovibrio bacteriovorus.
A phage infective for Bdellovibrio bacteriovorus was isolated. Electron microscopy revealed that it is tail-less, has a hexagonal appearance and two distinct capsomere layers, and is 60 to 70 nm in size. The nucleic acid appears to be single-stranded deoxyribonucleic acid. This is the first report of the isolation of a phage infective for B. bacteriovorus.
متن کاملChemotaxis by Bdellovibrio bacteriovorus toward prey.
A chemotaxis assay system that uses a modified Boyden chamber was characterized and used for measurements of chemotaxis by Bdellovibrio bacteriovorus strain UKi2 toward several bacterial species. Bacteria tested included both susceptible and nonsusceptible cells (Escherichia coli, Pseudomonas fluorescens, Bacillus megaterium, and B. bacteriovorus strains UKi2 and D). None was attractive to bdel...
