“…However, there was increased protoplast release at 4 h of incubation and the yields were 1.53 x 10 6 and 1.15 x 10 6 protoplast ml -1 for the respective stabilizers. Similar results were obtained in Penicillium expansum, Penicillium griseoroseum (Dias et al, 1997) and Aspergillus ochraceus (Almeida et al, 2008).…”

“…Os fungos de armazenamento estão presentes nas sementes recém-colhidas, geralmente em porcentagens baixas e são capazes de sobreviver em ambiente com baixa umidade, proliferando em sucessão aos fungos de campo causando a deterioração das sementes além de produzirem micotoxinas que causam intoxicações em humanos e animais (MILLER, 1995;NAKAGAWA, 2000). Uma das mais importantes micotoxinas é a ocratoxina A, produzida por vários fungos contaminantes, dentre deles destaca-se o fungo Aspergillus ochraceus (BATISTA et al;2003;SUÁREZ-QUIROZ et al, 2004;ALMEIDA et al, 2008).…”

“…Stable protoplasts in sufficient quantity for transformation were obtained, observing that there are several influencing factors in obtaining it, for example, the enzymatic preparation, the osmotic stabilizer, the age of mycelium, and the microorganism to be used (Almeida et al, 2008;Ishikawa et al, 2010). Even for S. macrospora, which was the first attempt to produce protoplasts, the quantities were favorable, ranging between 30-45 x 10 5 protoplasts/mL, and to S. maydis, of 40-45 x 10 5 protoplast/mL.…”
