Bdellovibrio bacteriovorus is a small parasitic bacterium present
in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative
bacteria, an important role in soil ecology has been suggested
for this organism. A study of effects of herbicides upon
Bdellovibrio might consequently be of considerable value.
In this study...
The growth of bdellovibrios at the expense of the host organism involves the catabolism of host cell macromolecular components and the subsequent anabolistic incorporation into bdellovibrio progeny. Extracellular enzymes specific for the various substrates provided by the host cell are present. In this study the extracellular RNase of Bdellovibrio bacteriovorus...
In an attempt to study the times in the lifecycle of
Bdellovibrio bacteriovorus at which various genes are
transcribed, the patterns of messenger ribonucleic acid
(mRNA) and ribosomal ribonucleic acid (rRNA) syntheses
were examined using two different types of hybridization
systems. The hybridization system using membrane bound
deoxyribonucleic acid (DNA)...
