title: [Sporulation and crystal formation in Bacillus thuringiensis during growth limitation via nutrient sources].
abstract: The object of the work was to study the effect of limiting concentrations of glucose, yeast extract, phosphorus, magnesium and potassium on the growth, spore formation and crystal formation in Bacillus thuringiensis subsp. galleriae. The deficiency of the above components was shown to interfere in no way with the processes of spore and crystal formation. However, the type of limiting substrate influenced the character of spore formation, the duration of different phases in the culture growth, the yield of spores and crystals, and their quality.
