| 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 |

| location of bacterial polysaccharide during various phases of growth. | polysaccharide-containing material was located by histochemical staining on ultrathin sections of bacillus cereus and several clostridial species during various phases of growth. these components were located along the cell wall in young vegetative cells and along the developing cortex in sporulating cells. in b. cereus any carbohydrate-containing material present along the forespore membrane was too small to be detected by direct staining. however, in three clostridial species such material was ... | 1969 | 4182530 |

| electron microscopic study of membranes and walls of bacteria and changes occurring during growth initiation. | thin sections of stationary-phase streptococcus lactis cells showed that the wall and membrane are 20 and 7 nm thick, respectively. whole cells were examined by negative staining with ammonium molybdate and by shadowing. on air-drying of whole cells, the membrane pulled away from the wall revealing adhesions between these organelles. adhesions could not be seen after subculture of the stationary-phase cells into complex media or into solutions containing glucose, kcl, and cacl(2) in tris(hydroxy ... | 1969 | 4180467 |

| occurrence of crithidia factors and folic acid in various bacteria. | crithidia factors and folic acid were found to be widely distributed in culture fluids and in cells of 27 species of bacteria, when cultured under aerobic conditions into the stationary phase. most bacteria excreted more crithidia factors and folic acid than they retained in their cells. one crithidia factor produced by serratia indica and one produced by bacillus cereus differed from biopterin in their chromatographic behavior. the factor excreted by s. indica appeared to be a 2-amino-4-hydroxy ... | 1970 | 5473887 |

| tryptophan catabolism during sporulation in bacillus cereus. | 1. two intermediates of tryptophan catabolism were isolated from a sporulating culture of bacillus cereus and identified as anthranilic acid and kynurenine by their spectral properties. 2. during sporulation the rate of formation of anthranilic acid and kynurenine by whole cells increased and reached a maximum at the pre-spore stage. 3. the specific activities of tryptophan pyrrolase and formylase also increased during sporulation and exhibited a maximal activity at the pre-spore stage. 4. kynur ... | 1970 | 4992321 |

| 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 |
| new antibacterial agent isolated from the avocado pear. | a group of eight new long-chain aliphatic compounds recently isolated from the avocado and some derivatives thereof were tested for antibacterial activity on 13 different species of bacteria and a yeast. some of these compounds inhibited the growth of microorganisms. 1,2,4-trihydroxy-n-hepadeca-16-en was found to be the most active, inhibiting certain gram-positive bacteria at 4 mug/ml. | 1970 | 4985830 |

| 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 |

| 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 |

| 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 |
