Abstract: Bacillus thuringiensis can be produced by a fermentative process using agro-industrial residues as substrates. The culture medium in solid state fermentation (SSF) is composed by moist nutrients. The water is a limiting factor in the SSF, differently from that in submerged fermentation. The solid culture medium must have a minimum moisture content to allow microbial growth but the concept of water availability in the substrate is best explained in terms of water activity (Aw). This study investigated the water…
