| [analysis of the changes in the electrophysical and morphometric parameters in the growth and sporulation periods of bacillus thuringiensis]. | changes in the electrophysical and morphometrical parameters of bacillus thuringiensis cells were studied during their growth and differentiation using the electrophysical procedure with the frequency of an alternating electric field varying within a wide range. the appearing variations were interpreted on the basis of the data about changes in the concentration of vegetative cells and spores, the optical density and ph of the cultural broth, and the assimilation of glucose by the culture. the c ... | 1984 | 6379383 |
| [effect of proteins on exoprotease synthesis by bacillus thuringiensis]. | bacillus thuringiensis was shown to grow better in media with albumin, gelatin and casein than in a chemically defined medium; proteins did not induce the synthesis of exoprotease. two maxima were found in the enzyme synthesis: the first one at the exponential phase of the cultural growth, and the second one during spore formation by the culture. the synthesis at the exponential growth phase was susceptible to nitrogen metabolite repression while the synthesis of exoprotease at the stationary ph ... | 1983 | 6358805 |
| two types of entomocidal toxins in the parasporal crystals of bacillus thuringiensis kurstaki. | two types of entomocidal proteins of bacillus thuringiensis kurstaki were isolated from the parasporal bodies (crystals), and their structures were compared with each other in relation to the toxic activity. when the crystals were dissociated in 2% 2-mercaptoethanol at ph 10, a protein of mr = 135,000, called delta-endotoxin, was liberated. the crystals of a strain of b. thuringiensis kurstaki, the hd-1 strain, also released another protein in small quantities. this minor component of hd-1, whic ... | 1983 | 6357098 |
| [activity of intracellular enzymes in bacillus thuringiensis prospores and sporangia]. | the activity of endocellular enzymes (alkaline phosphatase, protease, glucose dehydrogenase, aldolase, malate dehydrogenase, nadh dehydrogenase, nadh oxidase) was studied in isolated prospores and sporangia as well as in vegetative cells of bacillus thuringiensis strains, one of which produced crystals and one did not. the activity of malate dehydrogenase and nadh dehydrogenase was high in prospores of the both strains at the fifth and sixth stages of spore formation. the strain which did not pr ... | 1983 | 6341786 |
| cloning and expression of the crystal protein genes from bacillus thuringiensis strain berliner 1715. | from a clone bank of the entire genome of bacillus thuringiensis, one clone that contains a plasmid ( pbt 15-88) harboring a sporulation gene was identified by molecular hybridization. this gene, identified as the crystal protein gene, occurs both on a large host plasmid dna and in the chromosomal dna in b. thuringiensis strain berliner 1715. the inserted sequence of pbt 15-88, which corresponds to the chromosomal sequence, was not expressed in escherichia coli. in b. thuringiensis (kurstaki), t ... | 1982 | 6329704 |

| isolation and characterization of three autolytic enzymes associated with sporulation of bacillus thuringiensis var. thuringiensis. | cells of bacillus thuringiensis containing refractile spores autolyzed readily when suspended in buffer. the autolysate contained enzymes which lysed vegetative cell walls of the organism. three enzymes were isolated from the autolysate, and each was purified approximately 30-fold. one enzyme, most active near ph 4.0, was found to be an n-acetylmuramidase. the other two enzymes exhibited ph optima at 8.5. one was stimulated by cobalt ions and the other was not. the cobalt-stimulated enzyme was s ... | 1968 | 5732500 |
