Avaliação de técnicas de separação fluido-sólido na produção de bioinseticidas a partir de Bacillus sphaericus e Bacillus thuringiensis var. israelensis

The aim of this work was the use of flocculation/sedimentation and flotation techniques for production of bioactive concentrates os Bacillus thuringiensis var. israelensis and Bacillus sphaericus. Both are used as biological control agents to control larval insects related to endemic diseases such as yellow fever, filariasis and malaria. The fermented broths were produced batch wise from limpid and turbid cultivation media. The last one envisaging the reduction of the biolarvicides production costs. The addition of flocculating agents and pH effects on flocculation/sedimentation were studied. The process showed to be dependent on the microorganism strain, flocculated suspension characteristics and flocculating agent used.
