Catalase-producing strains of streptococci.
The genus Streptococcus includes organisms which are homofermentative, facultative with respect to oxygen, fastidious in their nutrient requirements, without cytochrome system, and are therefore considered to be catalase negative. Recent work in this laboratory revealed two strains of several hundred streptococci, screened from silage fermentations, that were capable of producing catalase. They...
متن کاملAntifungal Effect of Hydrogen Peroxide on Catalase-Producing Strains of Candida spp.
OBJECTIVE Clinical isolates of Candida were tested for the presence of catalase and susceptibility to hydrogen peroxide. METHODS MIC was tested by broth dilution technique and catalase was determined by a spectrophotometric procedure. RESULTS All 38 strains tested were inhibited by hydrogen peroxide in concentrations ranging from 4.4 to 88 mM/l, with non-albicans isolates generally requirin...
متن کاملBiological response of lactic streptococci and lactobacilli to catalase.
Addition of catalase to milk cultures of lactic streptococci resulted in increased rates of acid production, although it had no effect on cultures of lactobacilli. Milk cultures of both streptococci and lactobacilli produced detectable amounts of peroxide, which reached a maximum level in the early period of acid production followed by a drastic decrease as the acid production increased. Pyruva...
متن کاملCalcification of selected strains of streptococci.
Nine strains of cariogenic Streptococcus mutans and two strains of Streptococcus sanguis were tested for their ability to form hydroxyapatite. The cells were examined by X-ray diffraction and electron microscopy for apatite crystals after growth in a synthetic calcification medium. Each of the test isolates, except for one strain of S. sanguis, produced intracellular mineral. Two strains of S. ...
متن کاملAutolysis in strains of viridans streptococci.
Seven strains of viridans streptococci of the species Streptococcus sanguis, S. mutans and S. mitis were investigated for autolysis. The effect of pH, salt concentration and temperature on the autolytic process was studied in Na2HPO4/NaH2PO4 buffer. Whole cells and walls of all strains autolysed most rapidly at pH values above 7. Autolysis of whole cells of S. sanguis and one strain of S. mitis...
