To provide fruit throughout the whole year, maintain quality and reduce spoilage, apples pears are stored at low temperature. However, development of rots, caused mainly by Penicillium expansum, cannot be avoided. prevent losses, biological control has been proposed as a potential alternative. In this work, 16 psychrotrophic, non-pectinolytic Debaryomyces hansenii strains were evaluated in bioa...

Very few studies have been dedicated to R-hydroxyacids (R-HA) production using extracellular polyhydroxyalkanoate depolymerases (ePhaZs). Penicillium expansum produced maximum extracellular polyhydroxybutyrate depolymerase (~6 U/mL) by 72 h when grown in mineral salt medium containing 0.2 % w/v PHB, pH 5.0, at 30 °C and 200 rpm shaking conditions. Partial purification of the extracellular poly(...
