| germination of single bacterial spores. | changes in refractility and optical density occurring in individual spores of bacillus cereus t and b. megaterium qm b1551 during germination were investigated by use of a zeiss microscope photometer. the curves revealed that the germination process in single spores had two distinct phases; an initial rapid phase was followed by a second slower phase. under the experimental condition employed, the first phase of germination of b. cereus spores lasted for approximately 75 +/- 15 sec, whereas the ... | 1969 | 4977979 |
| properties of fructose 1,6-diphosphate aldolases from spores and vegetative cells of bacillus cereus. | fructose 1,6-diphosphate aldolase from cells of bacillus cereus appears to be typical class ii aldolase as judged by its functional and physical properties. spore and vegetative cell aldolase had similar enzymatic, immunochemical, and heat resistance properties in the absence of calcium, but they differed in their thermal stabilities in the presence of calcium, their stokes' radii, their mobility in acrylamide gel electrophoresis, and their molecular weights. the ph optimum for both enzymes was ... | 1969 | 4977985 |

| microgermination of bacillus cereus spores. | the biphasic nature of germination curves of individual bacillus cereus t spores was further characterized by assessing the effects of temperature, concentration of germinants, and some inorganic cations on microgermination. temperature was shown to affect both phases of microgermination as well as the microlag period, whereas the concentration of l-alanine and supplementation with adenosine exerted a significant effect only on the microlag period. the germination curves of individual spores ind ... | 1969 | 4982896 |

| regulation of penicillinase synthesis: evidence for a unified model. | the kinetics of penicillinase induction in bacillus cereus 569 was investigated. an increase in the rate of penicillinase synthesis was demonstrated within 30 sec of the addition of inducer (benzylpenicillin); however, the maximum induced rate of penicillinase synthesis was not attained until at least 30 min after the addition of inducer. in contrast to earlier claims, a quantitative estimate showed that the penicillinase messenger ribonucleic acid (mrna) half-life is approximately 2 min. these ... | 1970 | 4983646 |
| chemical composition of exosporium from spores of bacillus cereus. | homogeneous fragments of exosporium were extricated in centigram amounts from dormant spores of bacillus cereus and analyzed for intrinsic constituents. the membrane proved to be chemically complex but not unique, consisting mainly of protein (52%), amino and neutral polysaccharides (20%), lipids (18%), and ash (4%). seventeen common amino acids were identified by chromatography, and were present in usual proportions except for low levels of cystine-cysteine, methionine, tyrosine, and histidine. ... | 1970 | 4983648 |
| macromolecular synthesis during microcycle sporogenesis of bacillus cereus t. | microcycle sporogenesis induced in bacillus cereus t by phosphate limitation occurs over a narrow range of phosphate to spore inoculum ratios. sufficient phosphate is required to satisfy the demands for a twofold increase in deoxyribonucleic acid; net ribonucleic acid synthesis is not required. the total ribonucleic acid content of the culture was variable, and deoxyribonucleic acid synthesis was restricted to a twofold increase. developmental changes during outgrowth occurred synchronously, whe ... | 1970 | 4983651 |

| low-ph activation of bacillus cereus spores. | heat activation of bacterial spores at low ph was investigated in detail. unlike activation of spores in distilled water at a neutral ph, activation at low ph involves two superimposed processes: enhanced activation and death. low-ph-activated spores failed to germinate in d-alanine, in contrast to spores activated at neutral ph, owing to the abolition of alanine-racemase activity. morphological and permeability changes such as release and partial disruption of spores were dipicolinic acid-obser ... | 1970 | 4984072 |
| lipid composition of bacillus cereus during growth and sporulation. | the lipid composition of bacillus cereus during growth and sporulation was examined. the total lipid extract accounted for 2 to 3% of the dry weight of the cells and consisted of neutral lipids (30 to 40%) and phospholipids (60 to 70%). phospholipids were separated by thin-layer chromatography into eight components; phosphatidyl ethanolamine, phosphatidyl glycerol, and diphosphatidyl glycerol were the major phospholipids and accounted for over 90% of the total. also identified was a diglycosyl d ... | 1970 | 4984075 |

| derepression of beta-lactamase (penicillinase in bacillus cereus by peptidoglycans. | in bacillus cereus 569 a cellular inducer of beta-lactamase was isolated which has the same constituents and basic structure as the soluble peptidoglycan found in sporulation, extracts from spores, and germination extracts, and which was previously called "spore-peptide." the material has been extensively purified and characterized. two acid-soluble, high-molecular-weight peptidoglycan fractions containing muramic acid, glucosamine, diaminopimelic acid, d-aspartate, and d- and l-alanine, -lysine ... | 1970 | 4985545 |
| possible involvement of beta-lactamase in sporulation in bacillus cereus. | nonreverting beta-lactamase-negative strains were isolated from the beta-lactamase-constitutive strain, bacillus cereus 569 h. these strains differed from both beta-lactamase-inducible and -constitutive strains not only in failure to produce beta-lactamase but also in failure to autolyze on aging, delayed sporulation, and failure to release free spores from sporangia when produced. the addition of b. cereus beta-lactamase of 15% purity to a final concentration of 10 iu/ml stimulates sporulation ... | 1970 | 4985546 |

| microbioassay of antimicrobial agents. | a previously described agar-diffusion technique for microbioassay of antimicrobial agents has been modified to increase sensitivity of the technique and to extend the range of antimicrobial agents to which it is applicable. this microtechnique requires only 0.02 ml of an unknown test sample for assay, and is capable of measuring minute concentrations of antibiotics in buffer, serum, and urine. in some cases, up to a 20-fold increase in sensitivity is gained relative to other published standardiz ... | 1970 | 4986725 |
| transduction in bacillus cereus by each of two bacteriophages. | the ability of phage cp-51 to mediate transduction both homologously and heterologously in some of its hosts was investigated. cp-51 was shown to transduce bacillus cereus strains 6464, 9139, and t in addition to 569 which was reported earlier from this laboratory. furthermore, cp-51 grown on b. thuringiensis was shown to transduce some mutants of b. cereus. during this investigation, a second transducing phage for b. cereus 569 was isolated from lysates of phage cp-51 grown on b. cereus 6464. t ... | 1970 | 4986764 |
