Sophorolipids (SLs) are a group of extracellular biosurfactants produced by the yeast Starmerella bombicola. The present study explored the use of winterization oil cake (WOC), a residual oil cake that comes from the oil refining industry, as a substrate for the production of SLs by solid-state fermentation (SSF).

11 p, 705.7 KB The role of the protein kinase A pathway in the response to alkaline pH stress in yeast / Casado Vázquez, Carlos (Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; González Seviné, Asier (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular) ; Platara, Maria (Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Ruiz, Amparo (Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Ariño Carmona, Joaquín (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular)
Exposure of Saccharomyces cerevisiae to alkaline pH provokes a stress condition that generates a compensatory reaction. In the present study we examined a possible role for the PKA (protein kinase A) pathway in this response. [...]

35 p, 1.3 MB Co-composting of sewage sludge : fats mixtures and characteristics of the lipases involved / Gea Leiva, Teresa (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Ferrer i Alegre, Pau (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Álvaro Campos, Gregorio (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Valero Barranco, Francisco (Universitat Autònoma de Barcelona.

Departament d'Enginyeria Química, Biològica i Ambiental) ; Sánchez Ferrer, Antoni (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental)
Co-composting of sewage sludge and animal fat mixtures was studied in order to determine the possibility of using this technology to recycle fat-enriched wastes. A maximum fat content of 30% in fat:sludge mixtures is recommended to achieve the international sanitation requirements on compost quality and to avoid an excessive thermophilic composting time.

27 p, 1.4 MB Anaerobic co-digestion of a simulated organic fraction of municipal solid wastes and fats of animal and vegetable origin / Fernández, Anna (Escola Universitària Politècnica del Medi Ambient (Mollet del Vallès, Catalunya)) ; Sánchez Ferrer, Antoni (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Font i Segura, Xavier (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental)
The potential of mesophilic anaerobic digestion for the treatment of fats of different origin through co-digestion with the organic fraction of municipal solid wastes (OFMSW) has been evaluated. Co-digestion process was conducted in a pilot plant working in semi-continuous regime in the mesophilic range (37◦ C) and the hydraulic retention time (HRT) was 17 days. [...]

28 p, 813.8 KB Increasing biogas production by thermal (70ºC) sludge pre-treatment prior to thermophilic anaerobic digestion / Ferrer Martí, Ivet (GIRO Technological Centre) ; Ponsá Salas, Sergio (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química) ; Vázquez Lima, Felícitas (Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Font i Segura, Xavier (Universitat Autònoma de Barcelona. Departament d’Enginyeria Química, Biològica i Ambiental)
The objective of this work was to investigate the effect of a low temperature pre-treatment (70 °C) on the efficiency of thermophilic anaerobic digestion of primary and secondary waste sludge. Firstly, effect of sludge pre-treatment time (9, 24, 48 and 72 h) was evaluated by the increase in volatile dissolved solids (VDSs), volatile fatty acids (VFAs) and biogas production in thermophilic batch tests.
