title: Effect of the media composition on the growth parameters and biological properties ofBacillus thuringiensis var.israelensis delta-endotoxin.
abstract: The effects of media composition on growth parameters, total protein production (including delta-endotoxin) and its relation to the biological properties ofBacillus thuringiensis var.israelensis was investigated. The replacement of glucose by glycerol as the carbon source yielded higher concentrations of delta-endotoxin. This increase in toxicity was associated with increased amounts of the 130 kDa polypeptide fraction. The biocide activity was not related to haemolytic activity. specific growth rate nor spore count.
