| aromatic amino acid biosynthesis: gene-enzyme relationships in bacillus subtilis. | single step mutants of bacillus subtilis which required either one or all of the aromatic amino acids for growth were isolated. the relevant gene defect was determined for each mutant by enzyme assays in vitro. a mutant deficient in each enzyme step of aromatic amino acid biosynthesis was found with the exceptions of the shikimate kinase and the phenylalanine and tyrosine transaminases. representative mutants carrying the defective genes were mapped by deoxyribonucleic acid mediated transformati ... | 1967 | 4383672 |

| the survival of micro-organisms in space. further rocket and balloon-borne exposure experiments. | this report describes the results of survival studies of terrestrial micro-organisms exposed directly to the space environment on two balloons and in two rocket flights. the work is part of a program to develop techniques for the collection of micro-organisms in the size range of micrometeorite particles in space or non-terrestrial atmospheres, and their return to earth in a viable state for further study. previous survival studies were reported (j. hotchin, p. lorenz and c. hemenway, nature 206 ... | 1967 | 11973839 |
| use of ultrasonic energy in assessing microbial contamination on surfaces. | ultrasonic tanks were evaluated for their ability to remove viable microorganisms from various surfaces for subsequent enumeration. test surfaces were polished stainless steel, smooth glass, frosted glass, and electronic components. the position of contaminated surfaces in relation to the ultrasonic energy source, distance of the ultrasonic source from the test surfaces, and temperature of the rinse fluid were some of the factors which influenced recovery. experimental systems included both natu ... | 1967 | 16349743 |
| effect of microwaves on escherichia coli and bacillus subtilis. | suspensions of escherichia coli and bacillus subtilis spores were exposed to conventional thermal and microwave energy at 2,450 mhz. the degrees of inactivation by the different energy sources were compared quantitatively. during the transient heating period by microwave energy, approximately a 6 log cycle reduction in viability was encountered for e. coli. this reduction was nearly identical to what is expected for the same time-temperature exposure to conventional heating. heating of b. subtil ... | 1967 | 16349747 |
| transforming activity in both complementary strands of bacillus subtilis dna. | under conditions favoring single-strand transformation, the two complementary strands of bacillus subtilis dna, separated by differential complexing with polyriboguanylic acid, have identical transforming activity. moreover separated single strands, upon renaturation with unmarked (recipient) dna, form heteroduplex molecules with similar double-strand transformin activity. these findings bear upon the mechanism of dna integration. | 1967 | 17842787 |

| nuclear fraction of bacillus subtilis as a template for ribonucleic acid synthesis. | a "nuclear fraction" prepared from bacillus subtilis was a more efficient template than purified deoxyribonucleic acid for the synthesis of ribonucleic acid by exogenously added ribonucleic acid polymerase isolated from b. subtilis. the initial rate of synthesis with the nuclear fraction was higher and synthesis continued for several hours, yielding an amount of ribonucleic acid greater than the amount of deoxyribonucleic acid used as the template. the product was heterogenous in size, with a la ... | 1968 | 4296512 |

| fractionation of native and denatured transforming deoxyribonucleic acid from bacillus subtilis. | 1. native dna from bacillus subtilis was fractionated by stepwise elution from methylated albumin, the transforming activity being confined to two out of four fractions. partial separation of dna active in transformation for the arginine marker from that showing activity for the histidine and tryptophan markers was achieved. 2. partial denaturation of dna at 90 degrees and 93.5 degrees resulted in the preferential destruction of transforming activity for the histidine and tryptophan markers. 3. ... | 1968 | 4297046 |

| mode of action of melinacidin, an inhibitor of nicotinic acid biosynthesis. | melinacidin, a new antibacterial agent, blocked the synthesis of nicotinic acid and its amide in bacillus subtilis cells. the inhibitory activity of the agent was reversed by nicotinic acid, its amide, or nicotinamide adenine dinucleotides, but not by l-kynurenine, l-3-hydroxykynurenine, l-hydroxyanthranilic acid, or quinolinic acid. these properties indicated that the antibiotic interferes with the conversion of quinolinic acid to nicotinate ribonucleotide by the enzyme quinolinate phosphoribos ... | 1968 | 4234838 |

| actinomycin analogues containing pipecolic acid: relationship of structure to biological activity. | streptomyces antibioticus synthesizes a mixture of actinomycins which differ at the "imino acid" site of the peptide chains. in the presence of exogenous pipecolic acid, several new actinomycins were synthesized and 70% of the proline in the antibiotic mixture was replaced by the analogue. three new antibiotics (designated pip 1alpha, pip 1beta, and pip 2) were isolated from culture filtrates, purified, and crystallized. the molar ratio of pipecolic acid to proline was: pip 1alpha, 1:0; pip 1bet ... | 1968 | 4174667 |
| structural features of mesosomes (chondrioids) of bacillu subtilis after freeze-etching. | freeze-etched cells of bacillus subtilis have been studied with the electron microscope. the outer surface of the plasma membrane, i.e. the side facing the cell wall, is covered with numerous granules and short strands, each measuring approximately 50 a in diameter. these strands are occasionally seen to enter the cell wall. the inner surface of the plasma membrane, i.e. the side facing the cytoplasm, appears to be sparsely dotted with small particles measuring about 50 a. the envelope of mesoso ... | 1968 | 4175797 |

| primary adsorption site of phage pbs1: the flagellum of bacillus subtilis. | the adsorption of bacillus subtilis phage pbs1 was studied, and it was demonstrated that the primary adsorption site for this phage is the flagellum of b. subtilis. the capacity of flagella to function for motility may be lost without the loss of their capacity to adsorb the phage and permit infection. deoxyribonucleic acid injection by the phage is inhibited by cyanide, suggesting the requirement for cellular energy in the infection process. | 1968 | 4986906 |
