Summary
The influence of composition of media used for growth and delta-endotoxin production by B. thuringiensis var. kurstaki was studied with the idea of finding a cheap medium for attaining high yields of spore-crystal preparations. A new medium, based on malt sprouts is proposed. Data on growth and bioinsecticidal activity are given. A concentration of 2.1 × 109 spores.ml-1 was attained in a 48 h process. The spore-crystal preparations obtained present a LC50 of 2.18 × 108 spores.g-1 against larvae of Galleria mellonella.
