| mechanisms of enhancement of sp82 transfection. | sp82 transfection in bacillus subtilis could be markedly increased by exposing the competent cells to ultraviolet (uv)-irradiated homologous or heterologous cellular deoxyribonucleic acid (dna). this enhancement was similar in time and level of peak effect to enhancements effected by preinfection with helper phages or by uv irradiation of competent cells. the effectiveness of various dna preparations in increasing transfection paralleled the adenine plus thymidine content of the preparations and ... | 1968 | 4972781 |

| ribonucleic acid and protein synthesis in a mutant of bacillus subtilis defective in potassium retention. | a mutant of bacillus subtilis 168 (strain 168 kl), which had lost its normal capacity to accumulate k(+), was used to explore the interrelationship between protein and ribonucleic acid (rna) synthesis. in contrast to the wild type, the growth rate of strain 168 kl was markedly dependent on the k(+) concentration in the medium. k(+) uptake in the mutant strain was identical to that in the parent, but the mutant was unable to retain and accumulate k(+). protein synthesis was markedly dependent on ... | 1968 | 4972916 |
| gelatin-induced reversion of protoplasts of bacillus subtilis to the bacillary form: electron-microscopic and physical study. | protoplasts of bacillus subtilis plated on sd medium form l colonies in quantitative yield and propagate in the l form indefinitely. l bodies or protoplasts placed in 25% gelatin medium form bacillary colonies. details of the reversion of naked bodies to the walled form are reported. in 25% gelatin medium, reversion begins earlier (about 50% reversion in 4 hr) than the multiplication of bacilli. thus, virtually all the observed bacillary forms are themselves revertants and not the offspring of a ... | 1968 | 4972919 |

| limitations of thioglycolate broth as a sterility test medium for materials exposed to gaseous ethylene oxide. | although ethylene oxide is a reliable sterilizer, the process may be limited by diffusion. thus, situations may exist where microorganisms are protected from the sterilizing gas. it is possible that the exterior of a substance may be sterilized, whereas the interior is not. we investigated three general types of materials in which this limitation of diffusion could occur: the bore of glass and plastic tubing, the center of cotton balls, and plastic adhesive film/paper backing interface. these ma ... | 1968 | 4973064 |
| sporicidal effect of peracetic acid vapor. | the sporicidal activity of peracetic acid (paa) vapor at 20, 40, 60, and 80% relative humidity (rh) and 25 c was determined on bacillus subtilis var. niger spores on paper and glass surfaces. appreciable activity occurred within 10 min of exposure to 1 mg of paa per liter and 40% or higher rh. the sporicidal rate decreased from the optimum at 80% rh to a slight effect at 20% rh. spores on an impermeable surface were more difficult to kill than those on a porous one, probably because the cells te ... | 1968 | 4973068 |
| effect of streptomycin on some enzyme systems of bacillus subtilis. | streptomycin slightly inhibited lactic and malic dehydrogenases of bacillus subtilis, and inhibited isocitric dehydrogenase to about 60%. the formation of lactic dehydrogenase, glutamic dehydrogenase, alpha-alanine dehydrogenase, and succinic dehydrogenase was stimulated by the antibiotic at a concentration causing 50% inhibition of bacterial growth. streptomycin had practically no influence on the formation of malic dehydrogenase, but the antibiotic produced 48% inhibition of the synthesis of i ... | 1968 | 4973069 |
| dry heat resistance of spores of bacillus subtilis var. niger on kapton and teflon film at high temperatures. | to determine parameters that would assure sterility of a sealed seam of film for application in "split-seam entry," spores of bacillus subtilis var. niger were sprayed onto pieces of kapton and teflon film. short-time, high-temperature (200 to 270 c) exposures were made with film pieces between aluminum blocks in a hot-air oven, and the d and z values were determined after subculture of surviving spores. the use of kapton film allowed the study of high temperatures, since it is not heat sealable ... | 1968 | 4973071 |

| cross pathway regulation: effect of histidine on the synthesis and activity of enzymes of aromatic acid biosynthesis in bacillus subtilis. | l-histidine and, to a lesser degree, l-phenylalanine at concentrations of 10(-4)m inhibit the growth of leaky mutants (bradytrophs) of bacillus subtilis that are deficient in the synthesis of p-hydroxyphenylpyruvate, the first intermediate specific to tyrosine synthesis. the inhibition can be overcome by growth factor amounts of l-tyrosine and p-hydroxyphenylpyruvate. histidine and phenylalanine are capable of inhibiting the synthesis of tyrosine in several ways, and the major physiological effe ... | 1968 | 4973127 |
| common element in the repression control of enzymes of histidine and aromatic amino acid biosynthesis in bacillus subtilus. | single-step mutants of bacillus subtilis derepressed for enzymes of both aromatic amino acid and histidine biosynthesis were isolated. these mutants occur at a frequency of 10(-6) per cell per generation. all histidine enzymes as well as all enzymes of aromatic acid synthesis which were examined are maximally derepressed. this level cannot be repressed by growth on either histidine or tyrosine. some of the structural genes which specify the derepressed enzymes are linked to the aromatic cluster; ... | 1968 | 4973128 |

| sporulation in bacillus subtilis. the role of exoprotease. | 1. intracellular turnover of protein was measured in wild-type bacillus subtilis, which produces exoprotease at stage i in the sporulation process. protein is degraded at a rate of 8-10%/hr. 2. as a result of this turnover, the proteins of the mother cell are extensively degraded and resynthesized by about 6hr., so that the later stages of spore formation occur in a cytoplasm containing mainly ;new' protein. 3. the same protease appears to be responsible both for the intracellular turnover of pr ... | 1968 | 4972253 |
| sporulation in bacillus subtilis. antigenic changes during spore formation. | 1. antisera, prepared against extracts of cells and spores of bacillus subtilis, were used in immunoelectrophoretic studies of the changes occurring in cell extracts during the course of spore formation. 2. at least 15 antigens could be detected in vegetative-cell extracts by the antiserum prepared against cell extracts and at least seven could be demonstrated in spore extracts by the homologous antiserum. 3. cross-absorption studies showed that two of these antigens were probably completely spe ... | 1968 | 4972254 |
| sporulation in bacillus subtilis. biochemical changes. | 1. during the course of growth and sporulation of bacillus subtilis in chemically defined media, measurements were made of 16 different parameters, including the specific activities of nine intracellular enzymes. 2. towards the end of exponential growth, proteolytic activity increased and reached a maximum soon after growth ceased. 3. in the presence of an excess of phosphate the specific activity of alkaline phosphatase increased fivefold at the end of exponential growth. 4. the specific activi ... | 1968 | 4972255 |
| sporulation in bacillus subtilis. morphological changes. | 1. when bacillus subtilis was grown in a medium in which sporulation occurred well-defined morphological changes were seen in thin sections of the cells. 2. over a period of 7.5hr. beginning 2hr. after the initiation of sporulation the following major stages were observed: axial nuclear-filament formation, spore-septum formation, release of the fore-spore within the cell, development of the cortex around the fore-spore, the laying down of the spore coat and the completion of the corrugated spore ... | 1968 | 4972256 |
