Streptococcus sanguis strain N-2 was found to produce a bacteriocin (sanguicin) which accumulates intracellularly. It was purified by sequential procedures about 98-fold with a recovery of 37% and appeared to be homogeneous on gel electrophoresis. Sanguicin was heat labile and was destroyed by digestion with pronase. The growth of several species of oral indigenous microorganisms was inhibited by sanguicin, of which Bacteriodes melaninogenicus was most susceptible. Sanguicin acted on…

The production of bacteriocin-like substances by the oral bacterium Streptococcus salivarius.

Studies on the lytic enzyme from Streptococcus mutans. V. Prevalence of bacteria lytic against heated cells of Streptococcus sanguis ATCC 10558 in dental plaques of infants.

Bacteria lytic against heat-killed cells of Streptococcus (S .) sanguis ATCC 10558 were examined in dental plaques of 20 infants, and biological characterizations have shown that all of these lytic bacteria are S .

Production by Streptococcus sanguis of Bacteriocin-like Inhibitory Substances (BLIS) with Activity Against Streptococcus rattus

The BLIS, streptococcin san-K11, produced by S. sanguis strain K11 was partially purified from the supernatants of brain-heart infusion cultures and was stable to boiling for 10 min at acidic and neutral pH values but was inactivated in alkali.

Isolation and properties of the Capnocytophaga ochracea bacteriocin.

A bacteriocin from a subgingival plaque isolate of Capnocytophaga ochracea was purified and characterized. It was isolated from cell extract and had a molecular weight of 100,000. Streptococcus…

Bacteriocin-like substance (melaninocin) from oral Bacteroides melaninogenicus

Among the oral indigenous microorganisms, Bacteroides, Actinomyces, and streptococci were found to be sensitive to melaninocin.

Lactic acid production by oral Streptococcus mitis inhibits the growth of oral Capnocytophaga.

The present investigation showed that strains of Streptococcus mitis inhibited the growth of potential periodontopathic microorganisms, such as Actinobacillus actinomycetemcomitans, Capnocytophaga and species of Bacteroides and Fusobacterium.

Evaluation of Streptocin SH3, a Bacteriocin produced by Streptococcus sanguinis isolated from Human Dental Plaque

Bacteriocin produced from S. sanguinis has high activity against many pathogens and has high stability over wide ranges of temperature and pH, which makes it a good alternative in the medical and food preservation fields.

Properties of a Proteus morganii bacteriocin.

SUMMARY: The bacteriocin produced by Proteus morganii strain MR 336 is a thermolabile glycoprotein with a sedimentation constant of 4.0. Activity is dependent on the integrity of the complex and the…

Properties of a Lactobacillus fermenti bacteriocin.

The properties of a bacteriocin derived from Lactobacillus fermenti strain 466 were investigated and it was present in low titre in supernatant fluids from overnight broth cultures and was not inducible by ultraviolet radiation.

Alteration of macromolecular synthesis and membrane permeability by a Streptococcus sanguis bacteriocin.

This work exposed sensitive strain Wicky cells to Challis streptocin and observed macromolecular synthesis and membrane permeability.

Properties of a Streptococcus sanguis (Group H) Bacteriocin and Its Separation from the Competence Factor of Transformation

It appears, therefore, that initiation of the competent state for transformation in strain Wicky is not necessarily accompanied by gross alterations in cell growth and an association-dissociation relationship between macromolecules of 28,000 to 30,000 molecular weight is suggested.

Nature and Properties of a Staphylococcus epidermidis Bacteriocin

The effect of staphylococcin 1580 appeared to be bactericidal but not bacteriolytic; a large number of gram-positive bacteria were sensitive to Staphylococcus epidermidis 1580 action and was adsorbed to cell walls, cell membranes, and resistant cells.

Purification and Partial Characterization of a Bacteriocin from Serratia marcescens

Analytical studies show the bacteriocin to be essentially protein in nature containing less than one residue of glucose or phosphorus per 64,000 daltons.

Purification and Properties of a Bacteriocin-Like Substance (Acnecin) of Oral Propionibacterium acnes

The action spectrum of acnecin was very narrow; it was effective only against strains of non-acnecin-producing P. acnes and Corynebacterium parvum, a species closely related to P. Acnes.

Interference Between Gram-Positive Microorganisms in Dental Plaque

Data indicate that Streptococcus sanguis produces a broad inhibitory spectrum on other nonhemolytic streptococci, lactobacilli, corynebacteria, and actinomycetes, and certain Corynebacterium species and Lactobacillus casei inhibit the growth of Rothia dentocariosa and Actinomyces species.

The results are similar to those of previous studies, where the objective was to establish a cause-and-effect relationship, rather than a straightforward relationship between the number of cells and the content of the molecule.
