initiation of the germination of bacillus subtilis spores by a combination of compounds in place of l-alanine.l-alanine initiates the germination of spores of bacillus subtilis by entering two metabolic pathways. the products of one pathway, which is inhibited by d-alanine or by elevated temperature, can also be derived from a combination of fructose, glucose, and k(+). the present study demonstrated that the products of the other pathway can be derived from l-asparagine or l-glutamine or, to a lesser extent, from several other amino acids. hence, the combination of l-asparagine (or l-glutamine), fructo ...19684966545
timing of enzyme synthesis during outgrowth of spores of bacillus cereus. i. ordered enzyme synthesis.during outgrowth of spores of bacillus cereus t, the pattern of enzymes synthesized varied with respect to time. the periods of synthesis of alpha-glucosidase, l-alanine dehydrogenase, and histidase were ordered; each began at a specific time and synthesis continued for only a brief period. an examination of the timing of induced alpha-glucosidase and induced histidase was made to determine whether specific regions of the genome were continually available for transcription and regulation during ...19684966547

rapid and sensitive detection of bacteria by gas chromatography.a gas chromatograph fitted with electron capture and flame ionization detectors was employed for the rapid detection of bacteria by analysis for their metabolic products. the presence of proteus vulgaris, streptococcus faecalis, s. liquefaciens, escherichia coli b, bacillus cereus, and b. popilliae was detected in 2 to 4 hr in media inoculated with less than 10(4) cells per ml, whereas a 7- to 12-hr growth period was required for the detection of products formed in cultures of serratia marcescen ...19684967452

effects in hyperoxia upon microorganisms. i. membrane culture technique for exposing cells directly to test atmospheres.a membrane culture technique was developed for directly exposing microorganisms to test atmospheres. inhibition and killing were calculated from comparisons with air-grown cultures. direct colony counts were used with low inocula. with mass inocula, plate colony counts and optical-density measurements were made on resuspended filter populations. bacteria, including escherichia coli, were more sensitive to oxygen than previously reported. with inocula of a few hundred cells per membrane, five of ...19684967757

thiol-group binding of zinc to a beta-lactamase of bacillus cereus: differential effects on enzyme activity with penicillin and cephalosporins as substrates.zinc, which is required for the hydrolysis of cephalosporins by a crude enzyme from bacillus cereus 569, also increased the stability of this activity during storage. a loss in activity of the zinc-activated enzyme which occurred on prolonged hydrolysis of cephalosporin c was not restored by further addition of zinc. the thiol reagents n-ethyl maleimide (nem), iodoacetic acid (iaa), cdcl(2), and p-chloromercuribenzoate, all at 10(-3)m, and iodine at 1.6 x 10(-3)n prevent zinc activation of the " ...19684967769

microcycle sporogenesis of bacillus cereus in a chemically defined medium.a chemically defined medium which allowed germination, outgrowth, and subsequent resporulation of bacillus cereus t spores, without intervening cell division (microcycle sporogenesis), is described. no medium replacement was required. the second-stage spores were heat-stable and had similar germination characteristics and dipicolinic acid content to primary spores. deoxyribonucleic acid (dna) replication began soon after germination and there was a doubling in the dna content of the cells within ...19684967879

use of the scanning electron microscope for viewing bacteria in soil.scanning electron microscopy was used for viewing bacillus cereus and staphylococcus aureus in three different soils. both organisms were detected in the test soils at an approximate concentration of 10(7) cells per gram of soil; theoretically, the minimal number of microorganisms required for detection with the scanning electron microscope technique was between 10(7) and 10(10) cells per gram of soil. because the concentration of cells was critical, the use of scanning electron microscopy as an ...19684969663

lifetime of messenger ribonucleic acid for penicillinase synthesis in several strains of bacilli.1. previous studies of penicillinase synthesis in bacillus licheniformis showed that enzyme synthesis after the addition of actinomycin continues for far longer in the constitutive mutant 749/c than in the parental inducible strain (yudkin, 1966). this result was interpreted as indicating a difference in the lifetime of specific messenger rna in the two strains. other bacilli have now been examined in an attempt to see whether this difference is general. 2. there was no difference in the lifetim ...19684969990

fatty acids in the genus bacillus. ii. similarity in the fatty acid compositions of bacillus thuringiensis, bacillus anthracis, and bacillus cereus.the nature and relative abundance of fatty acids produced by two strains each of bacillus thuringiensis and of b. anthracis were studied by gas-liquid chromatography on a 12,000 theoretical plate polyester column capable of partially resolving iso- and anteiso-fatty acids with the same number of carbon atoms. unsaturated fatty acids as the bromo derivatives were separated from the saturated acids and resolved in a short se-30 column by use of programmed-temperature gas chromatography. all four s ...19684970227

relationship between protein and ribonucleic acid synthesis during outgrowth of spores of bacillus cereus.the rate of protein and ribonucleic acid (rna) synthesis was examined during the outgrowth of spores of bacillus cereus t in a chemically defined medium. rna synthesis started 2.5 min after the initiation of germination, and protein synthesis after 4 min. addition of a complete amino acid supplement and uracil supported high rates of rna and protein synthesis throughout outgrowth. to determine the relationship between the rate of protein (k) and rna synthesis, the kinetics of formation of variou ...19684970651

transducing bacteriophage for bacillus cereus.a phage, designated cp-51, that carries out generalized transduction in bacillus cereus 569 was isolated from soil. all auxotrophic mutants tested, those requiring tryptophan, histidine, leucine, isoleucine, methionine, or phenylalanine, were transduced to prototrophy. the phage was extremely unstable when stored at 2 to 4 c, but stability was enhanced by storage at higher temperatures. the optimal temperature of those tested for maintenance of plaque-forming units was 15 c.19684972780
diaminopimelate decarboxylase of sporulating bacteria.the meso-diaminopimelate (dap) decarboxylase of bacillus licheniformis, a pyridoxal phosphate-requiring enzyme, was stabilized in vitro by 0.15 m sodium phosphate buffer (ph 7.0) containing 1 mm 2,3-dimercaptopropan-1-ol, 100 mug of pyridoxal phosphate per ml, and 3 mm dap. when the meso-dap concentration was varied, the enzyme in cell-free extracts of b. licheniformis exhibited michaelis-menten kinetics. pyridoxal phosphate was the only pyridoxine derivative which acted as a cofactor. the enzym ...19684972917

change in the absorbancy of bacterial suspensions before initiation of growth.the apparent absorbancy of suspensions of stationary-phase cells of streptococcus lactis strain 354/07 decreased immediately after being placed in fresh media. this optical effect also occurred in defined mixtures of buffer glucose and kcl. cacl(2) caused the absorbancy to increase. cacl(2) and kcl together had about the same effect as kcl alone. srcl(2) could replace cacl(2), but it was less effective by a factor of 10(2). mncl(2), mgcl(2), and nacl were without effect. the absorbancy did not c ...19694975744
