| development of ultraviolet resistance in sporulating bacillus cereus t. | ultraviolet (uv) resistance patterns of sporulating bacillus cereus were determined. six different categories of uv resistance were discernible as the organism progressed from exponential growth to the free, mature spore. light microscope observations allowed the assignment of certain sporulation stages to specific uv resistance categories. marked changes in uv resistance were associated with stages iii, mid-iv, and post-iv of sporulation. dipicolinic acid was shown to sensitize forespores to uv ... | 1973 | 4200858 |

| sensitivity of three selected bacterial species to ozone. | the minimal lethal concentration of ozone in water was determined for three bacterial species: escherichia coli, bacillus cereus, and bacillus megaterium. a contact period of 5 min was selected. the lethal threshold concentration for the cells of b. cereus was 0.12 mg/liter while that for e. coli and b. megaterium was 0.19 mg/liter. low concentrations of ozone were ineffective when organic matter was present to interfere with the action of ozone on the bacterial cells. also determined during the ... | 1973 | 4201643 |

| screening and isolation of penicillinase inhibitor, ka-107. | it is known that penicillin resistance of bacteria is mainly caused by the inactivation of penicillin by penicillinase derived from such strains. we have developed a screening procedure for penicillinase inhibitors. several microorganisms were found to produce such inhibitors, and from the culture filtrate of streptomyces gedanensis atcc 4880 a penicillinase inhibitor, named ka-107, was isolated. the characteristics of this inhibitor were revealed by an in vitro test by using penicillinase deriv ... | 1973 | 4202340 |

| polysaccharides of the genus bacillus cross-reactive with the capsular polysaccharides of diplococcus pneumoniae type 3, haemophilus influenzae type b, and neisseria meningitidis group a. | we studied 174 strains of the genus bacillus for cross-reacting antigens to the capsular polysaccharides of groups a and c meningococcus, types i and iii pneumococcus, and haemophilus influenzae type b. cross-reactions were detected by immunodiffusion in agarose gel by using type-specific antisera and confirmed by absorption and inhibition experiments. of 20 bacillus pumilis strains, six had an antigen cross-reacting with group a meningococcal polysaccharide. other cross-reactions included one s ... | 1973 | 4150383 |

| ultrastructural study of poly- -hydroxybutyrate granules from bacillus cereus. | the freeze-etching technique was used to examine the effects of fracturing and etching on the appearance of poly-beta-hydroxybutyrate granules from bacillus cereus. these granules were examined in extracts isolated by hypochlorite or by sonic treatment, and also in fixed and unfixed intact cells; in the latter case they were compared with granules in thin sections of intact cells. after freeze-fracturing, the diameter of the granules in intact cells was between 240 and 720 nm. the granules consi ... | 1973 | 4123236 |
| electron transport system associated with membranes of bacillus cereus during vegetative growth and sporulation. | membranes isolated from bacillus cereus atcc 4342 during vegetative growth and during sporulation contained cytochromes b, c and a + a(3) as well as flavoprotein as determined from reduced-minus-oxidized difference spectra. although there appeared to be no qualitative change in the cytochromes, there was a significant increase in the amount of cytochromes associated with membranes isolated from sporulating cells. succinate and nicotinamide adenine dinucleotide (reduced form) (nadh) reduced the s ... | 1973 | 4125246 |
| production of bacteriophage by temperature-sensitive sporulation mutants of bacillus cereus t. | five temperature-sensitive sporulation mutants of bacillus cereus t have been isolated. these mutants are blocked at stage 0 of sporulation at the restrictive temperature (37 c) but are able to sporulate at nearly normal frequencies at the permissive temperature (26 c). a bacteriophage that forms a stable lysogen in the parent strain is induced at increased frequencies in the mutants. this induction is accompanied, in some of the mutants, by a reduction in immunity to the phage. revertants, sele ... | 1973 | 4126824 |

| penicillin-binding component of bacillus cereus. | (14)c-penicillin is irreversibly bound by bacillus cereus 569. incubation of penicillin-treated cells in a cell wall digestion medium results in solubilization of approximately 60% of the irreversibly bound lable. the extent of the solubilization is the same when cells are prepared by either a cold or 37 c treatment procedure. however, spheroplasts prepared by the cold treatment are leaky. when the resulting spheroplasts are incubated in supplemented medium, reduced rates and levels of penicilli ... | 1973 | 4196243 |
| outgrowth of bacillus cereus spores harboring bacteriophage cp-51 dna. i. initiation of bacteriophage development. | time of initiation of bacteriophage cp-51 rna synthesis, inhibition of host dna synthesis, initiation of cp-51 dna synthesis, and release of phage was determined in infected bacillus cereus cells and outgrowing spores harboring phage dna. the development of phage in outgrowing spores is initiated 45 min after induction of spore germination and then proceeds at a rate similar to that observed in infected cells. although spore rna synthesis is inhibited by the presence of chloramphenicol or puromy ... | 1973 | 4196633 |

| release and recovery of forespores from bacillus cereus. | a method is described which makes possible the release of immature forespores from sporulating cells at specific stages of development, from the completion of stage iii through to mature spore formation. with the aid of zonal density gradient centrifugation, the method makes possible the recovery of quantities of forespores ample for biochemical and physical studies. with the capability to examine forespores and some mother cell components independently, we have established that several enzymes ... | 1973 | 4199507 |
| exosporium and spore coat formation in bacillus cereus t. | the exosporium of bacillus cereus t was first observed as a small lamella in the cytoplasm in proximity to the outer forespore membrane (ofsm) near the middle of the sporangium. serial sections, various staining methods, and enzyme treatments failed to show any connections between the small lamella and the ofsm. the advancing edge of the exosporium moved toward the polar end of the cell until the spore was completely enveloped. the middle coat was formed between the exosporium and the ofsm from ... | 1973 | 4199508 |

| time course of purine nucleoside phosphorylase occurrence in sporulation of bacillus cereus. | purine nucleoside phosphorylase (ec 2.4.2.1) from bacillus cereus t was examined at hourly intervals during growth and sporulation. the enzyme has maximal activity in extracts prepared from cells during stages i and ii. the activity during exponential growth is only 6.6% of the maximum and that in free spores is only 3.3%. conservation of the purine nucleoside phosphorylase during sporulation is apparent as shown by the gradual increase in heat resistance. | 1972 | 4204910 |
| isotopic study of control of the lysine biosynthetic pathway during sporulation of bacillus cereus. | the extent of incorporation of aspartate into dipicolinic acid and into various amino compounds was determined in bacillus cereus at various times before, during, and near the end of synthesis of dipicolinic acid. the purpose of this study was to gain further information on the in vivo control of the biosynthesis of amino acids derived from aspartate. control of the lysine biosynthetic pathway was of particular interest with regard to sporulation, owing to the important role of diaminopimelate a ... | 1972 | 4204913 |
