Isolation of recombinant strains with enhanced pectinase production by protoplast fusion between Penicillium expansum and Penicillium griseoroseum Isolamento de linhagens recombinantes com maior produção de pectinases por meio de fusão de protoplastos entre Penicillium expansum e Penicillium griseoroseum
Protoplast fusion between complementary auxotrophic and morphological mutant strains of Penicillium griseoroseum and P. expansum was induced by polyethylene glycol and calcium ions (Ca2+). Fusant strains were obtained in minimal medium and a prototrophic strain, possibly diploid, was chosen for hapl...
