THE POLYSACCHARIDES SYNTHESIZED BY STREPTOCOCCUS SALIVARIUS AND STREPTOCOCCUS BOVIS

Identification of Streptococcus bovis and Streptococcus salivarius in clinical laboratories.

Streptococci identified as Streptococcus bovis, S. bovis variant, and Streptococcus salivarius were examined with respect to physiological and serological characteristics and cellular fatty acid content. Similarities in physiological reactions and problems encountered in serological analysis were noted, suggesting that an expanded battery of physiological tests is needed to definitively identif...

The Polysaccharides Synthesized by Strepto- Coccus Salivarius and Strepto-

In a previous paper (1) it was reported that certain non-hemolytic streptococci from the human throat are capable of synthesizing large amounts of a carbohydrate from sucrose and raffinose. These organisms seem to be similar to those studied by Oerskov and Poulsen (2). When grown on the surface of agar containing 5 per cent sucrose or raffinose, large mucoid colonies are produced which are abou...

Biofilm Formation by the Hexavalent Chromium Removing Strain Streptococcus salivarius: in Vitro Approach on Abiotic Surfaces

In this study, a strain of lactic acid bacteria Streptococcus salivarius was studied for its capacity to remove hexavalent chromium (Cr (VI)) from a liquid medium and to form biofilm. Both properties are useful for using the strain in bioremediation of metal-contaminated effluents. For biofilm formation capacity, three methods were used: the tube method (TM), the Congo red agar method (CRA) and...

In Vitro Effect of Hydroalcoholic Extract of Aloe Vera and 0.2% Chlorhexidine Mouthwash on Streptococcus Sanguinis, Streptococcus Salivarius and Streptococcus Mutans

Objectives: This study aimed to assess the antimicrobial effects of aloe vera hydroalcoholic extract and 0.2% chlorhexidine (CHX) mouthwash on Streptococcus sanguinis (S. sanguinis), Streptococcus salivarius (S. salivarius) and Streptococcus mutans (S. mutans) in vitro. Materials and Methods: Four concentrations (25%, 50%, 75% and 100%) of hydroalcoholic extract of aloe vera were prepared. S. ...
