Fig. 5.9SDS-PAGE analysis of the thermal and enzymatic yeast extracts. LineA: molecular
weight markers;B: thermal extract; andC: enzymatic extract. Molecular weights of the standards
are given on therightside of the gel (×10) (reprinted with permission from Mart ́ınez-Rodr ́ıguez

Taken together, these results thus imply a more general relevance of the use of
mannoproteins in enology and winemaking.
