The GAL1–MELT fusion protein retained strong antibacterial and anti-inflammatory activities, as well as collagen content modulation effects, confirming that MELT maintained its bioactivity. Apart from that, the GAL1–DsRed fusion protein was used as an additional protein target to evaluate the efficiency of the chitin-based column.

This study analyses the role of an antioxidant enzyme, the cytosolic peroxiredoxin Tsa1, in modulating trehalose metabolism in <i>Saccharomyces cerevisiae</i> wine strains during biomass production in molasses. Through comparative analyses in three commercial genetic backgrounds (L2056, T73, EC1118), we demonstrate that <i>TSA1</i> deletion generally leads to increased intracellular trehalose accumulation despite phenotypic variability among strains. Enzymatic assays revealed that Tsa1 does not regulate trehalose synthesis by altering glycolytic/gluconeogenic flux through pyruvate kinase. However, the deletion of <i>TSA1</i> resulted in increased oxidation of trehalose synthesis enzymes, as well as enhanced activity of trehalose-6-phosphate synthase and the trehalases Nth1 and Ath1, suggesting the involvement of peroxiredoxin in the futile cycle of trehalose synthesis and degradation. Scaling up the yeast biomass propagation process to semi-industrial conditions confirmed these findings, with increased trehalose levels in the <i>tsa1</i>∆ mutant correlating with enhanced desiccation resistance of the resulting biomass. These results highlight a novel Tsa1-dependent regulatory mechanism governing trehalose metabolism beyond its canonical antioxidant role.
