Possible enzymatic bases of bacteriolysis by bdellovibrios

Archiv f�r Mikrobiologie, 1973
Bdellovibrio sp. strain 6-5-S grows on and lyses autoclaved cells of Spirillum serpens strain VHL. The dissolution of the S. serpens cells is accompanied by a decrease in optical density and by a release of reducing substances, amino sugars, amino groups, and muramic acid into the culture supernatant. S.

BACTERIOLYSIS OF THE PSEUDOMONADS: I. AGENTS POTENTIATING LYSIS

Canadian Journal of Microbiology, 1964
The lytic spectrum of 10 species of pseudomonads in systems employing disodium EDTA, sodium deoxycholate, isoamyl alcohol, ethanol, thymol, or lysozyme was determined. Sodium deoxycholate and EDTA were the most active agents. Isoamyl alcohol, ethanol, thymol, and lysozyme elicited only slight lytic responses. EDTA, isoamyl alcohol, ethanol, and thymol

Physico-Chemical Nature of Bacteriolysis

Nature, 1944
WITHIN recent years, much attention has been paid to the antibacterial action of naturally occurring and synthetic products. The principal problem to be solved is that of the nature of the primary effect on the bacterial cell of the bacteriolytic or bacteriostatic agent.

On the Bacteriolysis by Lysozyme

The Journal of Immunology, 1938
Summary The bacteriolysis by lysozyme was studied by measuring the light-absorption of a lysing suspension, with a Moll-extinctiometer. In addition to a morphological study, this procedure was applied to the determination of lysozyme, which could be made within 5 per cent, and to a study of the influence of pH and electrolytes.

Factors affecting bacteriolysis using lysozyme in dual enzyme systems

Archives of Biochemistry and Biophysics, 1954
Abstract Dual-enzyme systems, in which lysozyme was present with papain or trypsin, were found to lyse heated cells of several species of bacteria normally resistant to either enzyme alone. The extent of lysis was often much greater than could be accounted for on the basis of additive action, and was considered a true synergism.

Suppression of penicillin-induced bacteriolysis of staphylococci by some anticoagulants

Journal of Antimicrobial Chemotherapy, 1987
Heparinoids and related negatively-charged substances caused suppression of the penicillin-induced bacteriolysis of staphylococci and a higher viability rate. Furthermore, the penicillin-induced release of cell wall material was reduced by these substances.

The synergistic action of lysozyme and trypsin in bacteriolysis

Archives of Biochemistry and Biophysics, 1955
Abstract The degree of synergism resulting from the concomitant action of lysozyme and trypsin on heated cells was influenced by cell and enzyme concentration, age, and pH of incubation. The enzyme system completely lysed species of the following genera: Aerobacter, Escherichia, Neisseria, Salmonella, Sarcina, Micrococcus, and Bacillus.

Bacteriolysis by vancomycin-conjugated acryl nanoparticles and morphological component analysis

Drug Development and Industrial Pharmacy, 2013
Nanoparticles are currently attracting considerable attention because of their ability to conjugate to various substances. As such, these nanoparticles can assist the transfer of the conjugated substance to target tissues where they are gradually released. In this study, vancomycin-conjugated nanoparticles (VCM NPs) were prepared.

Tightly regulated bacteriolysis for production of empty Salmonella Enteritidis envelope

Veterinary Microbiology, 2014
To avoid leaky expression of the bacterial host-toxic PhiX174 lysis gene E from the λpR promoter, a convergent promoter construct was made in which gene E was placed between a sense λpR promoter and an anti-sense P araBAD promoter. In the presence of l-arabinose, leaky transcription of lysis gene E at 28°C from the sense λpR promoter was repressed by ...

Galactose-sensitive mutants of Salmonella II. Bacteriolysis induced by galactose

Biochimica et Biophysica Acta, 1961
When the mutants of Salmonella lacking UDPGal-4-epimerase were grown in the presence of galactose, they exhibited marked bacteriolysis in ordinary medium and were convested to soheroplasts in hypertomic medium. Lysis was not observed in non-growing cells.
