| incorporation of bacteriophage genome by spores of bacillus subtilis. | takahashi, i. (microbiology research institute, ottawa, ontario, canada). incorporation of bacteriophage genome by spores of bacillus subtilis. j. bacteriol. 87:1499-1502. 1964-the buoyant density in a cscl gradient of deoxyribonucleic acid (dna) extracted from spores of bacillus subtilis was found to be identical to that of dna from vegetative cells. density-gradient centrifugation of dna of spores derived from cultures infected with phage pbs 1 revealed the presence of a minor band whose densi ... | 1964 | 14188727 |

| actinomycin resistance in bacillus subtilis. | the incorporation of uracil-c(14), a precursor of cellular rna, into whole cells of the sensitive parent strain bacillus subtilis no. 6051 is completely inhibited by actinomycin d, whereas only partial inhibition of uracil-(14) incorporation occurs with actinomycin-resistant intact cells of b. subtilis strain ii 15. incorporation of uracil-c(14) into protoplasts of the resistant strain of b. subtilis is completely inhibited. the sensitivity of resistant-cell protoplasts to drug effect clearly su ... | 1964 | 14186467 |

| the effect of low temperatures on the structure of enzymes. | the enzymes of the cold stable organisms possess lower levels of activation energy. a possibility for the adaptation of living creatures to low temperatures is finally associated with the structural alterations in proteins and enzymes. polarographic studies on yeast alcohol dehydrogenase and on proteinase of b. subtilis at low temperatures have demonstrated that a lowering of temperature causes significant structural changes in the protein molecule. | 1964 | 11881645 |
| biological contamination of mars. i. survival of terrestrial microorganisms in simulated martian environments. | it has been postulated that the accidental introduction of terrestrial microorganisms to other planets during the course of space exploration might impede or bias the detection of organic matter and possible indigenous organisms, and thereby confuse subsequent studies of extraterrestrial life. to assess the likelihood of biological contamination of mars, we have applied the principle of natural selection on a laboratory scale. terrestrial microorganisms were collected from a variety of environme ... | 1964 | 11883443 |
| some biological and physical factors in dry heat sterilization: a general review. | there is a surprising lack of quantitative data on sterilization by dry heat so that microbiologists have little knowledge of the role played by various biological and physical factors in this sterilizing process. a recent investigation by the author has shown that the aerobic mesophilic bacterial sporeformers, such as bacillus subtilis and bacillus coagulans, are the most resistant among several species of sporeforming bacteria to dry heat sterilization. the type of carrier on which the spores ... | 1964 | 11883444 |

| comparison of methods of extracting intracellular proteases from bacteria. | five commonly used methods of disintegrating bacterial cells were compared by use of bacillus subtilis, pseudomonas putrefaciens, and streptococcus durans as the test organisms. these methods were: (i) sonic treatment, (ii) grinding, (iii) freezing and thawing, (iv) acetone-powder, and (v) toluene. sonic treatment and grinding yielded more protein in the cell-free extracts than did the other methods. likewise, the protease activities (micrograms of tyrosine liberated per milliliter of extract) o ... | 1965 | 4956035 |
| thermal inactivation characteristics of bacillus subtilis spores at ultrahigh temperatures. | the thermal inactivation characteristics of bacillus subtilis a spores suspended in skim milk with the use of large-scale ultrahigh temperature (uht) processing equipment were investigated in terms of survival as measured with two plating media. data on survival immediately after uht treatments were recorded in temperature-survivor curves, time-survivor curves, and decimal reduction time (drt) curves. the temperature-survivor curves emphasized that inactivation is accelerated more by increases i ... | 1965 | 4956036 |
| heat injury of bacillus subtilis spores at ultrahigh temperatures. | the following three criteria indicated that bacillus subtilis a spores were injured, but not completely inactivated, by ultrahigh temperature treatment. (i) significant reductions in survivors were observed when spores were enumerated with a standard medium but not when the medium contained added cacl(2) and sodium dipicolinate. (ii) after a damaging heat treatment, more survivors were enumerated with the standard medium after incubation at 32 c than at 45 c, which was opposite to the result wit ... | 1965 | 4956037 |
