Active Biopolymeric Films Inoculated with Bdellovibrio bacteriovorus, a Predatory Bacterium
نویسندگان
چکیده
The objective of the present work was to evaluate novel active films made with biopolymeric matrices as carriers a living Bdellovibrio bacteriovorus HD100 strain, predatory bacterium antimicrobial potentials against pathogens. Biopolymer were prepared by casting method using following mixtures: collagen/sodium alginate/sorbitol (CA-S), alginate/glycerol (CA-G), and tapioca starch/sodium (StA-G). effects film formulations on viability B. investigated Fourier Transform Infrared (FTIR) spectroscopy, Differential Scanning Calorimetry (DSC), Electron Microscopy (SEM). SEM showed that morphology not altered in polymeric films. FTIR spectroscopy provided information about structural composition CA-S less reduction after its entrapment; thus, proved be better agent for immobilization preservation enhance activities during application Escherichia coli.

Initiation of Chromosomal Replication in Predatory Bacterium Bdellovibrio bacteriovorus
Bdellovibrio bacteriovorus is a small Gram-negative predatory bacterium that attacks other Gram-negative bacteria, including many animal, human, and plant pathogens. This bacterium exhibits a peculiar biphasic life cycle during which two different types of cells are produced: non-replicating highly motile cells (the free-living phase) and replicating cells (the intracellular-growth phase). The ...
متن کاملThe Predatory Bacterium Bdellovibrio bacteriovorus Aspartyl-tRNA Synthetase Recognizes tRNAAsn as a Substrate
The predatory bacterium Bdellovibrio bacteriovorus preys on other Gram-negative bacteria and was predicted to be an asparagine auxotroph. However, despite encoding asparaginyl-tRNA synthetase and glutaminyl-tRNA synthetase, B. bacteriovorus also contains the amidotransferase GatCAB. Deinococcus radiodurans, and Thermus thermophilus also encode both of these aminoacyl-tRNA synthetases with GatCA...
متن کاملBspK, a Serine Protease from the Predatory Bacterium Bdellovibrio bacteriovorus with Utility for Analysis of Therapeutic Antibodies
The development of therapeutic and diagnostic antibodies is a rapidly growing field of research, being the fastest expanding group of products on the pharmaceutical market, and appropriate quality controls are crucial for their application. We have identified and characterized the serine protease termed BspK (Bdellovibrio serine protease K) from Bdellovibrio bacteriovorus and here show its acti...
متن کاملProteome-based comparative analyses of growth stages reveal new cell cycle-dependent functions in the predatory bacterium Bdellovibrio bacteriovorus.
Bdellovibrio and like organisms are obligate predators of bacteria that are ubiquitously found in the environment. Most exhibit a peculiar dimorphic life cycle during which free-swimming attack-phase (AP) cells search for and invade bacterial prey cells. The invader develops in the prey as a filamentous polynucleoid-containing cell that finally splits into progeny cells. Therapeutic and biocont...
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.
