| 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 |

| the composition of beta-lactamase i and beta-lactamase ii from bacillus cereus 569-h. | 1. crystalline beta-lactamase i from bacillus cereus 569/h yielded only amino acids on acid hydrolysis, but crystalline beta-lactamase ii from the same organism yielded also substantial quantities of neutral sugars and amino sugars. 2. analysis with an amino acid analyser indicated that the two enzymes were similar though not identical in overall amino acid composition. analysis of neutral and amino sugars as their silyl derivatives by gas-liquid chromatography showed that the carbohydrate moiet ... | 1970 | 4990590 |

| characteristics of a bacteriocin derived from streptococcus faecalis var. zymogenes antagonistic to diplococcus peumoniae. | a bacteriocin-producing strain of streptococcus faecalis var. zymogenes (e-1) was isolated from clinical material (conjunctiva). the active substance differed from bacteriocins described by other investigators primarily in its spectrum of antibacterial activity, especially by its marked inhibition of diplococcus pneumoniae. the e-1 bacteriocin also inhibited nonhemolytic strains of enterococci as well as one-third of the viridans group of streptococcal strains investigated. the degree of inhibit ... | 1971 | 4398532 |

| evidence for a magnesium pump in bacillus cereus t. | unlike escherichia coli, bacillus cereus t appears to accumulate mg(2+) in its cell sap against a concentration gradient. over a range of mg(2+) in the growth medium from 5 x 10(-5) to 1.35 x 10(-2)m, the concentration of mg(2+) in the cell sap of b. cereus t was maintained at about 6 x 10(-3)m, and ribosome-bound mg(2+) and spermidine, as well as the spermidine concentration in the cell sap, appear to be unaffected by the concentration of mg(2+) in the growth medium. inhibition of growth of e. ... | 1971 | 4993319 |
| 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 |
| 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 |
