| growth of bacteriophage phi 105 and its deoxyribonucleic acid in radiation-sensitive mutants of bacillus subtilis. | growth of phage phi105 and its deoxyribonucleic acid (dna) was studied in radiation-sensitive mutants of bacillus subtilis. the reca gene is required for optimal prophage induction with mitomycin c and for infectivity of prophage dna. rec b gene is required for marker rescue from mature dna. the importance of bacterial genes for phage dna activity seems to depend on phage dna structure. | 1971 | 5006010 |

| sporulation in bacillus subtilis. effect of medium on the form of chromosome replication and on initiation to sporulation in bacillus subtilis. | thymine-requiring mutants of bacillus subtilis and mutants that are temperature-sensitive for initiation of chromosome replication have been used to study the relationship between sporulation and chromosome formation. the dna synthesis that normally occurs when cells are transferred to sporulation medium is essential for spore induction. this is shown by the fact that thymine-starved cells are unable to form spores and are unable to perform even the earlier steps of sporulation, such as septum f ... | 1971 | 5004200 |

| effect of relative humidity on formaldehyde decontamination. | death rate studies were conducted to determine the effect of varying the concentration, humidity, and type of surface on the sporicidal activity of formaldehyde gas. washed and unwashed spores were similarly exposed to detect the influence of residual nutrient growth medium upon the rate of kill. the results indicated that the sporicidal activity of formaldehyde gas varies directly with its concentration. relative humidities (rh) over 50% proved essential for sterility. spores on a porous surfac ... | 1971 | 5002898 |
| production of l-arginine by arginine hydroxamate-resistant mutants of bacillus subtilis. | l-arginine hydroxamate inhibited the growth of various bacteria, and the inhibition was readily reversed by arginine. l-arginine hydroxamate (10(-3)m) completely inhibited the growth of bacillus subtilis. this inhibitory effect was prevented by 2.5 x 10(-4)ml-arginine, which was the most effective of all the natural amino acids in reversing the inhibition. l-arginine hydroxamate-resistant mutants of bacillus subtilis were isolated and found to excrete l-arginine in relatively high yields. one of ... | 1971 | 5002904 |

| regulation of two aspartokinases in bacillus subtilis. | when grown on minimal glucose medium, transformable bacillus subtilis strains contained two distinct aspartokinases (atp:l-aspartate 4-phosphotransferase, ec 2.7.2.4). one of these enzymes was inhibited by l-lysine (lys), whereas the other was insensitive to inhibition but was activated by l-leucine. none of the other amino acids tested had any effect, and the addition of l-threonine did not enhance the inhibition by lys, in contrast to the concerted inhibition observed for other bacilli. at the ... | 1971 | 5003173 |
| role of autolysins in the killing of bacteria by some bactericidal antibiotics. | the rapid lysis of bacillus licheniformis nctc 6346 and b. subtilis 168 trp caused by vancomycin and d-cycloserine can be inhibited by stopping protein synthesis. protein synthesis must be stopped for more than one doubling time of the cells before addition of wall inhibitors. poorly lytic mutants (lyt(-)) of b. licheniformis required 10 to 20 times the concentration of vancomycin or cycloserine to be added to growing cultures to cause even slow lysis. at lower concentrations growth of the mutan ... | 1971 | 5003174 |
| evidence suggestive of compartmentalization of deoxyribonucleic acid-synthesizing systems in freeze-treated bacillus subtilis. | freezing of bacillus subtilis in liquid nitrogen results, upon thawing of the cells, in an enhanced deoxyribonucleoside triphosphate and reduced thymidine (tdr) incorporation into cellular deoxyribonucleic acid (dna). the dna synthesized from thymidine triphosphate (ttp) was made by a "repair"-type system as determined by density transfer experiments. the mono- and diphosphate precursors were also incorporated by a "repair"-type synthesis. when tdr was used as the radioactive precursor in the as ... | 1971 | 5003175 |
| division mutants of bacillus subtilis: isolation and pbs1 transduction of division-specific markers. | a procedure for the isolation of bacillus subtilis mutants that appear to be defective in septum synthesis has been described. fourteen mutants isolated with this technique were found to be located at four distinct loci on the b. subtilis chromosome. these have been designated diva, divb, divc, and divd. the four mutants in the diva group synthesize septa; however, they do so with a high frequency of error resulting in minicell production. mapping data were obtained by scoring cotransduction fre ... | 1971 | 5003180 |

| effects of ph on transformation of bacillus subtilis with single-stranded deoxyribonucleic acid. | variation in frequencies of transformation mediated by native and single-stranded dna and its dependence on ph of the medium were investigated. the results indicate that the biological activity of deoxyribonucleic acid (dna) of both configurations assayed in the presence of ethylenediaminetetraacetic acid (edta) increases as the ph of the transformation mixture is lowered from 7.7 to a maximum transformation frequency near ph 6.1. at this lower ph, native dna transforms equally in medium with an ... | 1971 | 4997538 |
| relationship between competence for transformation of bacillus subtilis with native and single-stranded deoxyribonucleic acid. | the response of populations of bacillus subtilis to both native deoxyribonucleic acid (dna) and denatured dna was investigated at maximal competence and at various times during the development of compentency. the results indicate that competence for transformation with native and denatured dna increases and decreases simultaneously. competition occurs between native and single-stranded dna during transformation, and the same cells in a population can be doubly transformed by dna molecules of bot ... | 1971 | 4997539 |
| isolation and characterization of tricarboxylic acid cycle mutants of bacillus subtilis. | a technique was developed for the detection, on agar, of mutants of bacillus subtilis that lacked a functional tricarboxylic acid cycle. mutants devoid of detectable levels of aconitase, isocitric dehydrogenase, alpha-ketoglutarate dehydrogenase, succinic dehydrogenase, fumarase, and malate dehydrogenase have been isolated and characterized. several mutants with conditionally expressible lesions, including a mutant with a heat-sensitive citrate synthase, have also been isolated. all of the mutan ... | 1971 | 4997541 |
| repair of radiation damage to deoxyribonucleic acid in germinating spores of bacillus subtilis. | the repair of deoxyribonucleic acid (dna) in germinating spores was studied in comparison with that in vegetative cells. radiation-induced single-strand breaks in the dna of spores and of vegetative cells of bacillus subtilis were rejoined during postirradiation incubation. the molecular weight of single-stranded dna was restored to the level of nonirradiated cells. the rate of the rejoining of dna strand breaks in irradiated spores was essentially equal to that in irradiated vegetative cells. t ... | 1971 | 4997542 |
| variation in the primary structure of bacillus subtilis flagellins. | the flagella derived from 18 strains bacillus subtilis were tested for their reaction with antiflagellar filament antibody and antiflagellin antibody. on the basis of their reactivity, at least five serologically distinct classes could be identified. peptide map analysis of tryptic digests of the subunit proteins were consistent with the immunochemical analysis. large differences in sequence existed among proteins of the different classes; proteins within an antigenic group differed by only a fe ... | 1971 | 4997543 |
| minor threonine dehydratase encoded within the threonine synthetic region of bacillus subtilis. | challenging auxotrophs on metabolites that are precursors of a biosynthetic step involving a mutated enzyme has revealed a new class of suppressor mutations which act by derepressing a minor enzyme activity not normally detected in the wild-type strain. these indirect, partial suppressor mutations which allow isoleucine auxotrophs to grow on homoserine or threonine have been analyzed to determine their effect on enzymes involved in the biosynthesis of these amino acids. it has been found that on ... | 1971 | 4997544 |
