摘要：

In the present work, studies of glucose oxidase (GOD) production in solid-state fermentation on polyurethane foams, using mussel processing wastewaters (MPW) as culture media, were carried out. Initially, the results generated in this experimental modality were compared with those that were obtained in conventional submerged fermentation. Later on, cultures were tested in solid state with fed-batch performance, defining suitable conditions of operation. These conditions were finally corroborated in experiments with a bioreactor of own design. in which GOD production was improved 13 times regarding to the initial cultures. (C) 2009 Elsevier Inc.
