Crystalline inclusions in Bacillus thuringiensis.
Crystalline inclusion bodies resembling those seen in Clostridium cochlearium were detected in cultures of Bacillus thuringiensis infected with bacteriophage.
متن کاملprotein patterns and larvicide activity of crystalline inclusions of bacillus thuringiensis ssp. kumamotoensis dsm 6070
morphological and electrophoretic analysis of the crystalline inclusions (parasporal crystals) of sporulated cultures of b. thuringiensis ssp. kumamotoensis dsm 6070 (bt 6070) was conducted via phase contrast and scanning electron microscopy and sodium dodecyl sulphate-polyacrylamide gel electrophoresis. the activity of the spore-crystal suspensions against house fly (musca domestica) larvae wa...
متن کاملDifferentiated pattern of protein composition of crystalline inclusions of newly isolated Bacillus thuringiensis strains from Silesia in Poland.
Protein profiles of crystal delta-endotoxins were determined in twenty nine Bacillus thuringiensis strains-soil and phylloplane isolates--from Poland. Electrophoretic analysis revealed quantatively and qualitatively different patterns of delta-endotoxin crystal preparations of these B. thuringiensis strains. The crystalline parasporal inclusions of B. thuringiensis isolates were composed of two...
متن کاملRegulation by overlapping promoters of the rate of synthesis and deposition into crystalline inclusions of Bacillus thuringiensis delta-endotoxins.
During sporulation, Bacillus thuringiensis produces intracellular, crystalline inclusions comprised of a mixture of protoxins active on insect larvae. A major class of these protoxin genes, designated cry1, is transcribed from two overlapping promoters (BtI and BtII) utilizing RNA polymerase containing sporulation sigma factors sigma(E) and sigma(K), respectively. Fusions of these promoters to ...
متن کاملSerological Studies on the Formation of Protein Parasporal Inclusions in Bacillus Thuringiensis
A strain of Bacillus thuringiensis has been isolated, and methods have been developed for separation of the crystalline, parasporal inclusions in a pure form. Normal sporulation with concomitant crystal formation takes place when cells are incubated under suitable conditions in a nutrient free medium. Serological techniques have been used to study the origin and development of the crystals. Rab...
