A method of quantitative determination of beta-exotoxin content in liquid and dry bioformulations has been developed. The method includes a thin-layer chromatography to isolate beta-exotoxin from accompanying nucleotides, the further desorption of a single beta-exotoxin spot by water and to carry out spectrophotometry at 259 and 330 nm. beta-exotoxin(More)
Accumulation of Bacillus thuringiensis subsp. thuringiensis beta-exotoxin (BET) in the course of industrial fermentation (a stage in the production of the entomocidal biopreparation bitoxibacillin) has been studied. It has been demonstrated in model experiments that the decrease in the content of BET in the culture fluid is accounted for by the toxin(More)
New methods were developed and applied to quantitative determination of beta-exotoxin and antibiotic activity of delta-endotoxin with respect to Micrococcus spp. in bitoxibacillin (BTB) and the fermentation broths prepared under industrial conditions. The biosynthesis of beta-exotoxin in the period of its maximum accumulation during the fermentation was(More)
