Abstract
Grapevine co-products, as canes, represent a source of compounds of interest to control vineyard diseases with a sustainable approach. We chose to study an extract that we produced from grapevine trunk and roots. This extract, enriched in complex stilbenes, strongly reduced mycelial growth and spore germination of Botrytis cinerea, the fungal agent causing gray mold. The most active stilbenes were resveratrol, r-viniferin, and ε-viniferin. This grapevine extract also inhibited the production of Botrytis laccases. Conversely, Botrytis secretome metabolized resveratrol into δ-viniferin and pallidol (2 dimers); and ε-viniferin, a dimer, into hopeaphenol, r-viniferin, and r2-viniferin (3 tetramers). r-Viniferin and hopeaphenol (2 tetramers) were not metabolized. The biotransformed extract maintained an effective antimycelial activity. This study provides evidence that a grapevine extract enriched in oligomerized stilbenes exerts different anti-Botrytis activities, notwithstanding the ability of the fungus to metabolize some stilbenes.

Abstract
<b>Background and Objective:</b> Laccase is classified as an oxidoreductase enzyme that catalyzes oxidation reactions of phenolic groups by using oxygen as its electron acceptor. Laccase isolated from <i>Trametes versicolor</i> (L.) Lloyd has a wide range of applications in the industrial sector. The use of enzymes in the industrial sector requires pure enzyme conditions from impurities so that the enzyme can maximize its ability in converting the substrate. This study aims to obtain enzyme activity and the characteristic of purified laccase enzymes isolated from <i>Trametes versicolor</i> (L.) Lloyd. <b>Materials and Methods:</b> This study was conducted with an experimental method followed by descriptive analysis. The steps of this research consist of a qualitative assay of laccase enzyme, crude laccase extract desalting by Sephadex G-25, laccase purification by Sephadex G-100 and laccase optimum pH characterization. <b>Results:</b> The result of this study showed that purification of laccase from <i>Trametes versicolor </i>(L.) Lloyd with Sephadex G-25 increases laccase enzyme-specific activity which is 10.966 U mg<sup>1</sup> and reaches 2.93-fold purity. The highest laccase enzyme activity was achieved at pH 4 with a value of laccase activity 62.39 U L<sup>1</sup>. <b>Conclusion:</b> Based on current results, purifying laccase from <i>Trametes versicolor </i>(L.) Lloyd with Sephadex G-25 was recommended which resulting higher enzyme specific activity.

Abstract
In this work, we statistically improved culture media for rPOXA 1B laccase production, expressed in Pichia pastoris containing pGAPZαA-LaccPost-Stop construct and assayed at 10 L bioreactor production scale (6 L effective work volume). The concentrated enzyme was evaluated for temperature and pH stability and kinetic parameter, characterized by monitoring oxidation of different ABTS [2, 20-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] substrate concentrations. Plackett-Burman experimental design (PBED) implementation improved previous work results by 3.05-fold, obtaining a laccase activity of 1373.72 ± 0.37 U L-1 at 168 h of culture in a 500 mL shake flask. In contrast, one factor experimental design (OFED) applied after PBED improved by threefold the previous study, additionally increasing the C/N ratio. Employing OFED media at 10 L bioreactor scale was capable of producing 3159.93 ± 498.90 U L-1 at 192 h, representing a 2.4-fold increase. rPOXA 1B concentrate remained stable between 10 and 50 °C and retained over 70% residual enzymatic activity at 60 °C and 50% at 70 °C. Concerning pH stability, the enzyme was stable at pH 4.0 ± 0.2 with a residual activity greater than 90%. The lowest residual activity (60%) was obtained at pH 10.0 ± 0.2. Furthermore, the apparent kinetic parameters were V max of 3.163 × 10-2 mM min-1 and K m of 1.716 mM. Collectively, regarding enzyme stability our data provide possibilities for applications involving a wide range of pH and temperatures.
