In shake flask andfermentor studies, various media components and culture inocula were tested to improve P. fumosoroseus spore production rates, yield and stability. To evaluate inoculum potential and inoculum scale-up for fermentor studies, conidia and liquid culture-produced spores of various strains ofP. fumosoroseus were compared as inoculum. Inoculation of liquid cultures with blastospores...

Recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. In an industrial fermentation of Bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. Changes in certain plasmid resident properties o...

Microbial enzymes produced using biological processes are of great importance due to their contribution sustainable solutions for agricultural production. In our previous study, the chitinase enzyme from Lactobacillus coryniformis was purified, immobilized zinc oxide (ZnO) nanoparticles, and its effectiveness as a bioinsecticide against storage pest Sitophilus zeamais Motschulsky, 1855 (Coleopt...
