| requirement for coenzyme a in the phosphoroclastic reaction of anaerobic bacteria. | various bacteria which degrade pyruvate by the phosphoroclastic reaction were examined with respect to the role of coenzyme a (coa) in this reaction. the strictly anaerobic bacteria, which cleave pyruvate by the phosphoroclastic reaction characteristic of clostridia, required catalytic levels of coa for the co(2)-pyruvate exchange and acetoin-forming portions of the phosphoroclastic reaction. these reactions were reversibly inhibited by the coa analogue, desulfo-coa. in contrast, using cell-free ... | 1969 | 4982893 |
| protein synthesis in cell-free extracts of streptococcus faecalis. | if a cell-free extract of streptococcus faecalis is fractionated by way of a 10 to 70% sucrose gradient, at least three areas are found capable of protein synthesis having a density greater than can be accounted for by association of individual ribosomes. these areas represent distinct "polysome" peaks rather than random distribution of polymers of varied length. they appear to be membrane subunits. in addition there is a further particle with a density of about 150s, incapable of protein synthe ... | 1969 | 4982894 |

| new medium for blood cultures. | a new medium suitable for blood cultures is described. it contains dextrose, cysteine, iron, and magnesium, in a tris(hydroxymethyl)aminomethane buffer, and a mixture of peptones derived from animal tissues, casein, and yeast. in comparison with trypticase soy broth, the growth rate constants of staphylococcus aureus, streptococcus (viridans group), enterococcus, and escherichia coli were higher in this medium, and growth appeared earlier in a significant number of clinical blood cultures. | 1969 | 4886863 |
| role of pyruvate metabolism in the growth of streptococcus faecalis in the presence of propionate. | the growth of streptococcus faecalis is inhibited by propionate, and the inhibition is reversed by lipoic acid or acetate. a study of the role of pyruvate oxidation in s. faecalis showed that propionate inhibited the lipoic acid-dependent aerobic oxidation of pyruvate in resting cells. pyruvate dehydrogenation with neotetrazolium as a hydrogen acceptor in cell-free extracts also required lipoic acid and was markedly inhibited by propionyl phosphate as well as sodium propionate. some lipid substa ... | 1969 | 4974385 |
| procedure for evaluating the effects of 2,450-megahertz microwaves upon streptococcus faecalis and saccharomyces cerevisiae. | modifications of a commercial 2,450-megahertz microwave oven were made so that 6 ml of microbial suspension could be exposed to the microwave field for various periods of time. the microorganisms were contained in the central tube of a modified liebig condenser positioned in the approximate geometric center of the oven cavity. kerosene at -25 c was circulated through the jacket of the condenser during microwave exposure permitting microwaves to reach the microbial suspension. flow rates of the k ... | 1969 | 4975450 |

| autolytic enzyme system of streptococcus faecalis. v. nature of the autolysin-cell wall complex and its relationship to properties of the autolytic enzyme of streptococcus faecalis. | cell walls from exponential-phase cultures of streptococcus faecalis atcc 9790 contain an autolysin (a beta-n-acetylmuramide glycanhydrolase, e.c. 3.2.1.17) which has been isolated from trypsin-speeded wall autolysates. the autolysin, which was excluded from bio-gel p-60, was further fractionated by diethylaminoethyl (deae)-cellulose chromatography or filtration on bio-gel p-200. after deae-cellulose chromatography, which removed most of the wall polysaccharide, autolysin activity was extremely ... | 1969 | 4977984 |

| effect of carbon dioxide on the aspartic acid requirement for proteinase biosynthesis by streptococcus faecalis var. liquefaciens. | non-proliferating cells of streptococcus faecalis var. liquefaciens required aspartic acid for proteinase biosynthesis in the absence of co(2) but not in the presence of co(2). | 1969 | 4982668 |
| dependence of protease secretion by streptococcus faecalis var. liquefaciens on arginine and its possible relation to site of synthesis. | washed cells of streptococcus faecalis var. liquefaciens, when harvested from media that supported protease biosynthesis, continued to release this extracellular enzyme in phosphate buffer. the addition of ethylenediaminetetraacetic acid (edta) halted the secretion. if zinc ions were added to the edta-treated cells before 45 to 60 min had elapsed, a fraction of the anticipated enzyme activity was observed. after 60 min, arginine and phosphate, in addition to zinc, were necessary for the demonstr ... | 1969 | 4974395 |
