| 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 |
| 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 |
| 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 |
| 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 |
| 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 |

| enumeration and identification of bacillus cereus in foods. i. 24-hour presumptive test medium. | an egg yolk-polymyxin medium (kg) for rapid enumeration of bacillus cereus is described. the test is presumptive in that differentiation of b. cereus (and closely related organisms) from other species is based on the formation of turbidity in the agar surrounding the colonies of the cereus group organisms. the medium is formulated to encourage sporulation and release of free spores for serological confirmatory tests within the 24-hr incubation period. the production of turbidity in egg yolk and ... | 1971 | 4331768 |
| ultrastructural changes associated with activation and germination of bacillus cereus t spores. | the ultrastructural changes occurring during defined stages of the transition of dormant bacillus cereus t spores into heat-sensitive forms were investigated. the coat of the heat-activated spores displayed conspicuous striations across its middle layer. electron microscopy of thin sections of heat-activated spores revealed the presence in the spore of a layer consisting of hexagonally oriented subunits. it was demonstrated that the subcoat region, but not the cortex, disappears rapidly during g ... | 1971 | 4993322 |
| reduction of activity of reduced nicotinamide adenine dinucleotide oxidase by divalent cations in cell-free extracts of bacillus cereus t. | a rapid and effective method was devised for the reduction of activity of reduced nicotinamide adenine dinucleotide (nadh) oxidase in crude extracts of bacillus cereus t. the addition of 25 mumoles of mncl(2) per mg of extract protein in tris(hydroxymethyl)aminomethane-hydrochloride buffer reduced nadh oxidase activity by 90% within 1 min, and this reduction was independent of ph between ph 7.0 and 8.5. other divalent cations such as mg(2+), ba(2+), ca(2+), and co(2+) also reduced nadh oxidase a ... | 1971 | 4993337 |

| control of diaminopimelate decarboxylase by l-lysine during growth and sporulation of bacilluscereus. | l-lysine caused repression of diaminopimelate decarboxylase synthesis in bacillus cereus when grown in either a minimal defined medium (cdgs medium) or a complex defined medium (a modified lysine assay medium). when cells were grown in either of the two media, variations in the specific activity of the enzyme as a function of time were found to be correlated with the intracellular lysine pool size during growth. from all of the data presented, it seems reasonable to conclude that during growth t ... | 1971 | 4995650 |

| sporulation of a cortexless mutant of a variant of bacillus cereus. | a stage 4 sporulation mutant of a strain of bacillus cereus var. alesti fails to synthesize a cortex although all other structural components appear normal. with terminal lysis the spore core as well as the sporangium is lysed. both the uptake of (45)ca and the synthesis of dipicolinic acid (dpa) are similar to these activities in the parent strain, but these components (dpa and ca) are lost to the medium with the drastic lysis. the first stage of diaminopimelic acid incorporation, that into ger ... | 1971 | 4993321 |

| dielectric study of the physical state of electrolytes and water within bacillus cereus spores. | dielectric measurements revealed that dormant spores of bacillus cereus have extremely low conductivities at high frequencies (50 mhz) and so must contain remarkably low concentrations of mobile ions both within the core and in the surrounding integuments. activation, germination, and outgrowth were all accompanied by increases in conductivity of the cells and their suspending medium, and this result indicated that intracellular electrolytes had become ionized and leaked from the spores. high-fr ... | 1971 | 4998245 |
| spore refractility in variants of bacillus cereus treated with actinomycin d. | refractility as indicated by light microscopy, electron microscopy of thin sections, and freeze fracture etching was increased and maintained in a cortexless mutant, a(-)1, of bacillus cereus var. alesti by the addition during sporulation stage 4 of actinomycin d, which prevents the terminal lysis of spore core associated with sporulation in this organism. (45)calcium uptake levels and dipicolinic acid (dpa) content were similarly maintained. the location of these components appears to be in the ... | 1971 | 4998247 |
