A mis padres Agradecimientos Llegado este momento y dado que la lectura de los agradecimientos siempre parece que suscita un interés especial voy a intentar aunar esfuerzos para recordar todo lo vivido y compartido a lo largo de estos años. Y es que, a pesar de pertenecer al mundo de la ciencia y de la tecnología, la vida está llena de vivencias y emociones y supongo que, será por ello, por lo que en los últimos meses me han animado diciendo “Venga Ana, que ya se ve la luz al final del túnel”, y es que esta tesis como una parte importante de mi vida ha estado llena de luces y sombras. Entre las sombras, la incertidumbre ante un nuevo experimento, ensayos que no salen a la primera a pesar de que sus autores en los artículos de referencia no señalan ningún contratiempo, equipos que se rompen en el momento en el que necesitas utilizarlos y un sin fin más de cosas, que a día de hoy, una vez completado el trabajo se empiezan a ver desde otra perspectiva. Las luces por el contrario sois todos vosotros, los que de una forma u otra habéis compartido conmigo esta experiencia. Gracias a mis directoras de tesis, Puri y Marta, por haber confiado en mí desde el principio, por guiarme y adentrarme en el mundo de la investigación, por compartir conmigo vuestro bagaje científico y personal. El aprendizaje obtenido seguro que en el futuro forma implícitamente parte de mi personalidad. Gracias a todos mis compañeros de laboratorio, a los que estaban incluso antes de que yo llegara.

Ruti, gracias por las risas y confidencias que hemos compartido tanto en la uni como fuera, tu forma de ser resume lo buena gente que eres. Crespi, gracias por abrirme los ojos, por fin sé “quién es mi papi”☺. Gracias por tu buen rollo, por saber aunar fiesta de noche y minuciosidad en el labo durante el día, eres todo un crack! Y finalmente, y no por ello menos importante, gracias a los compañeros que me han acompañado hasta el final. Cascan, nos unió la enología y al final el vino y la química han seguido en nuestras vidas. Gracias por tus consejos, tus ánimos, por ofrecerme tu ayuda siempre que lo he necesitado y por ser un amigo. Marivel, vales un montón y por eso creo que he aprendido tanto contigo, como diría José Miguel, incluso hasta hablo un poco de guacamayo. Muchas gracias por tener siempre un ratito para mi y por los ratos de cháchara que hemos pasado, como a ninguna de las dos nos gusta hablar…A Pilar y Cristina, compañeras de labo y de despacho, porque tanto los buenos momentos como los días en que parece que se tuerce todo, cuando se comparten son más llevaderos y vosotras habéis estado ahí. Gracias por vuestro apoyo. Gracias a Natalia, Tamara, Jesús Ángel y Javi por vuestra ayuda en la realización de una de las partes experimentales de este trabajo. Gracias por vuestra predisposición, ganas de trabajar y hacer las cosas bien. A Rodrigo, Judith, Nieves, Jose, Maite, Jesús y Miguel por vuestros consejos, por preocuparos por mi y por los buenos ratos pasados en la cafetería y en cenas y comidas navideñas… A Federico Echávarri, por ayudarme a trabajar los datos de color y a todos los profesores de química y de enología que me han dado la formación que hoy en día dispongo y a la que he recurrido en muchos momentos a lo largo de esta tesis. A Nines, Ernesto y Pedro Felipe, porque como profesionales sois muy buenos, de eso no hay duda, pero como personas sois excepcionales. Gracias porque me habéis aportado mucho y muy bueno. A mis compañeros de otras áreas, por los ratitos de palique en el pasillo, que han hecho más ameno las idas y venidas del laboratorio al despacho, del despacho a la sala de catas, o del laboratorio a la bodega. Y en especial a Lara y Javi, nos unió la química y desde entonces algún tipo de enlace se creó entre nosotros. Gracias por vuestro apoyo desde la distancia. A todos los panelistas que han participado en las sesiones de cata haciendo posible que una parte importante de este trabajo haya sido realizada. Gracias por vuestra disponibilidad y tiempo. A los compañeros del PAS, gracias por facilitarme el trabajo día a día. Al personal de limpieza y en especial a Ana. Gracias por darme los buenos días siempre con una sonrisa. A mis actuales compañeros del CIDA, por preocuparos por el estado de la tesis, por vivir conmigo los últimos meses previos al depósito y solventarme las dudas trascendentales de última hora. A mis compañeros de enología, porque el comienzo de esta carrera implicó el inicio de esta tesis. Gracias a Sandra y a Vesna, por seguirme la pista, por animarme y preocuparos por mí. Gracias a mis amigos/as, por vuestros ánimos y comprensión, porque casi para que me pongáis cara os tendría que haber dejado una foto.

Submitted for publication: September 2005 Accepted for publication: April 2006 Key words: Non-Saccharomyces, yeasts, vineyards, cellars, fermentation, wine. The contribution by the numerous grape-must-associated non-Saccharomyces yeasts to wine fermentation has been debated extensively. These yeasts, naturally present in all wine fermentations, are metabolically active and their metabolites can impact on wine quality. Although often seen as a source of microbial spoilage, there is substantial contrary evidence pointing to a positive contribution by these yeasts. The role of non-Saccharomyces yeasts in wine fermentation is therefore receiving increasing attention by wine microbiologists in Old and New World wine producing countries. Species that have been investigated for wine production thus far include those from the Candida, Kloeckera, Hanseniaspora, Zygosaccharomyces, Schizosaccharomyces, Torulaspora, Brettanomyces, Saccharomycodes, Pichia and Williopsis genera.

To the best of my knowledge and belief, no material described herein has been previously published or written by any other person except when due reference is made in the æxt. If accepæd for the awa¡d of Doctor of Philosophy, this thesis wilt be available for loan or photocopy Elizabeth Joy Waters ü Abstract Unstable grape juice and wine proteins can cause cloudiness or deposits in wine after bottling resulting in adverse effects on consumer acceptance. This is of concern to white wine producers and frning with bentonite to remove protein is an established winery practice. However, such methods are inconvenient, non-specific and can result in extensive flavour loss. In this study, proteins responsible for hazp, have been isolated and characterized, and their interaction with wine polysaccharides has been explored. An examination of the use of peptidases to remove such proæins was also undertaken. To get a reliable estimate of the concentration of grapo juice and wine proteins it was necessary to determine their amino acid composition. The commonly used Bradford dye- binding assay grossly underestimates the protein concentration by 50 to 807o and in addition, grape and wine phenolic compounds were found to strongly interfere.

  • Heat-Unstable Proteins in Wine. I. Characterization and Removal by Bentonite Fining and Heat Treatment JUINN-CHIN HSU ~ and DAVID A
    Heat-Unstable Proteins in Wine. I. Characterization and Removal by Bentonite Fining and Heat Treatment JUINN-CHIN HSU ~ and DAVID A. HEATHERBELL 2 The effect of bentonite fining on the total proteins and the heat-unstable (80°C, 6 h; 4°C, 12 h) proteins in GewLirztraminer, White Riesling, Sauvignon blanc, and Sylvaner wines was investigated. Protein molecular weights (MW), isoelectric points (pl), and glycoproteins were determined by using lithium dodecyl sulfate polyacrylamide gel electrophoresis (LDS PAGE) and two-dimensional isoelectric focusing-lithium dodecyl sulfate (IF-LDS) electrophoretic techniques with silver staining as well as protein blotting for glycoprotein detection. Rel- ative concentrations of proteins in stained gels were determined by laser scanning densitometry. Bentonite fining tends to remove the higher pl (5.8- 8.0) and intermediate MW (32 000- 45 000) protein fractions first. How- ever, these represent only a small proportion of the soluble proteins. In general, it is necessary to remove the lower pl (4.1 - 5.8), lower MW (12 600 and 20 000- 30 000) fractions, which contain glycoproteins and represent the major component of the proteins, to protein stabilize wines to heat testing. Protein fractions with MW of 60 000 to 65 000 and having a wide range of pl (4.1 - 8.0) were highly resistant to removal by bentonite fining and remained in protein-stabilized wine. In addition, trace amounts of fractions with MW of 28 000 may remain in GewiJrztraminer and White Riesling wines and 25 000 in Sauvignon blanc wines. Unstable proteins precipitated by heat tests were recovered and analyzed.
