| interrelationship between the intestinal microflora of lackey moth, brown-tail moth and the entomopathogenic bacterium bacillus thuringiensis. | the interrelationship between the intestine microflora of lackey moth (malacosoma neustria l.), brown-tail moth (nygmia phaeorrhoea l.) and entomopathogenic bacteria bacillus thuringiensis (berl.), bac. thuringiensis var. galleriea, and bac. thuringiensis kr3 was studied in vitro. various organisms of the intestine microflora of lackey moth display bacteriostatic action towards bac. thuringiensis var. galleriea and bac. thuringiensis kr3 which is not typical of the microflora of brown-tail moth ... | 1975 | 2842 |
| study of the sporulation of bacillus thuringiensis var. thuringiensis. | during the submerged cultivation of bacillus thuringiensis var. thuringiensis in 300- and 3000-liter fermentors, lysis occurred at the end of the exponential phase of growth. new vegetative cells were subsequently formed which usually sporulated. at time of lysis, the amount of soluble sugar was 1-12 g/liter, ph value dropped to 5.3-5.8 from the original ph 6.8 and started to rise after all the cells had lysed. the proteolytic activity was low during the lysis and increased as the sporulation co ... | 1975 | 1076 |
| metalloprotease from bacillus thuringiensis. | bacillus thuringiensis var. kurstaki was shown to produce an extracellular, metal chelator-sensitive protease during the early stages of sporulation. protease production in nutrient broth was dependent upon supplementation with mn2+ or ca2. the addition of ca24 was required for enzyme stabilization... | 1975 | 241290 |
| an insect toxin from spores of bacillus thuringiensis and bacillus cereus. | spores of bacillus thuringiensis contain a toxin active against lepidopterous larvae. this toxin can be solubilized by extraction with reagents which dissolve the protein crystal of b thuringiensis. it is inactivated by crystal-specific antiserum. spores of bacillus cereus contain a similar toxin although the specific activity is much lower than the spores of b. thuringiensis. the b. cereus toxin contains a single major polypeptidecomponent. toxic activity can be solubliized from spores of both ... | 1975 | 806656 |
| lipid metabolism during bacterial growth, sporulation, and germination: an obligate nutritional requirement in bacillus thuringiensis for compounds that stimulate fatty acid synthesis. | the regulation of fatty acid biosynthesis by compounds that are required for growth of bacillus thuringiensis was investigated using an vivo assay developed to measure fatty acid synthesis in germinating spores. a minimal glucose-ammonium-salts medium does not support growth even though previous radiorespirometric studies have shown b. thuringiensis to possess intact tricarboxylic acid and embden-meyerhof-parnas pathways. abundant growth does occur, however, when this medium is supplemented with ... | 1975 | 807563 |

| [elimination of the thermostable exotoxin from b. thuringiensis after ingestion in the mouse]. | when ingested by mice, the thermostable exotoxin is quickly eliminated in the "faeces", without fixation on the liver, the heart, the spleen or the kidneys. by quantitative study with a radio-active tritium-labelled exotoxin, this elimination is shown to be almost complete in 24 hours. | 1975 | 809165 |

| physiology of sporeforming bacteria associated with insects: minimal nutritional requirements for growth, sporulation, and parasporal crystal formation of bacillus thuringiensis. | a defined medium is described in which 18 strains of bacillus thuringiensis representing the 12 established serotypes grow, sporulate, and produce a parasporal crystal. this minimal medium contains glucose and salts supplemented with either aspartate, glutamate, or citrate. these organic acids are required and cannot be replaced by vitamin mixtures or succinate even though succinate is taken up at a rate similar to that of aspartate, glutamate, and citrate. | 1974 | 4844274 |
| physiology of sporeforming bacteria associated with insects: radiorespirometric survey of carbohydrate metabolism in the 12 serotypes of bacillus thuringiensis. | radiorespirometry was used to compare the primary pathways of glucose catabolism in 18 strains of bacillus thuringiensis representing the 12 established serotypes. every strain utilizes the embden-meyerhof-parnas pathway almost exclusively; pentose-phosphate pathway participation is minor. the embden-meyerhof-parnas pathway predominates regardless of whether the cells were grown in a minimal medium or one containing yeast extract. the results indicate that the absolute requirement for citrate an ... | 1974 | 4844275 |

| heterotrophic nature of the cell-free protein-synthesizing system from the strict chemolithotroph, thiobacillus thiooxidans. | a cell-free protein-synthesizing system prepared from the strict chemolithotroph, thiobacillus thiooxidans, was similar to that of heterotrophs. the poly-u directed system had a temperature optimum of 37 c, but in the presence of spermidine (3 mm) the optimum shifted to 45 c. although growth of the chemolithotroph occurs only in acid conditions, the ph optimum for the cell-free system was ph 7.2. the endogenous-directed activity in the presence or absence of spermidine was maximal at ph 7.8. spe ... | 1974 | 4590488 |

| effect of the exotoxin of bacillus thuringiensis on normal and ecdysone-stimulated ribonucleic acid polymerase activity in intact nuclei from the fat-body of sarcophaga bullata larvae. | a nuclear preparation from the fat-body of sarcophaga bullata was obtained which incorporates nucleotides at a steady rate. two activities, differing in their response to alpha-amanitin, are present. the activities are not separated by changes in the concentration of (nh(4))(2)so(4) as effectively as in mammalian nuclei. the activity resistant to alpha-amanitin is stimulated by ecdysone, and both normal and the ecdysone-stimulated activities are inhibited by the exotoxin. the amanitin-sensitive ... | 1973 | 4797896 |
| effect of an exotoxin from bacillus thuringiensis on deoxyribonucleic acid-dependent ribonucleic acid polymerase in nuclei from adult sarcophaga bullata. unusual behaviour of eukaryotic polymerases to inhibitors. | the dna-dependent rna polymerase activities in nuclei isolated from adult sarcophaga bullata are unusual in their responses to metal ions, ionic strength and inhibitors. there is an activity that is sensitive both to rifamycin and to alpha-amanitin. the activity is less sensitive to bacillus thuringiensis exotoxin than is larval polymerase, and low concentration of exotoxin provoke a slight stimulation. | 1973 | 4797897 |

| inhibition of hepatic deoxyribonucleic acid-dependent ribonucleic acid polymerases by the exotoxin of bacillus thuringiensis in comparison with the effects of -amanitin and cordycepin. | the action of bacillus thuringiensis exotoxin, a structural analogue of atp, on mouse liver dna-dependent rna polymerases was studied and its effects were compared with those of alpha-amanitin and cordycepin. (1) administration of exotoxin in vivo caused a marked decrease in rna polymerase activity of isolated nuclei at various concentrations of mg(2+), mn(2+) and (nh(4))(2)so(4). a similar action was recorded after addition of exotoxin to isolated nuclei from control or exotoxin-treated mice.
