The objective of this work was to evaluate the physiological and anatomical traits of plants of a cacao (Theobroma cacao) clone in response to water deficit after leaf application of silicon. A randomized complete block design was used, with four replicates, in a 2x3 factorial arrangement of two water regimes (irrigated or nonirrigated) and three silicon concentrations (0.0, 1.5, and 3.0 mg mL‑1) applied in wettable SiO2 powder. The plants were evaluated 20 days after the irrigation regimes were applied. The use of SiO2 increased the stability of cell membranes and the photochemical efficiency of the plants under water deficit. The 1.5 mg mL‑1 concentration of SiO2 increased photosynthetic rate, water use efficiency, and carboxylation efficiency, besides mitigating the effect of oxidative stress. Stomatal density was reduced in nonirrigated plants under the highest concentration of Si. The 1.5 mg mL‑1 concentration of Si is considered optimal for the photosynthetic metabolism of young cacao plants under soil water limitation. |

The effect of different concentrations of tannic acid (TA) and wheat bran (WB) for the synthesis of tannase and other hydrolytic enzymes produced by solid-state fermentation (SSF) and its potential in the extraction of phenolic compounds (phenolic acids, anthocyanins and proanthocyanidins) from grape pomace (GP) were evaluated. For this, different percentages of TA (0?12%) and WB in GP (8?92%) were used. The best SSF media composition was a 1:1 ratio of WB to GP, called mixed medium (MM). In addition, the extraction from GP with the obtained enzymatic pool was compared to a commercial enzyme and a hydroethanolic extraction (HE). The results showed that the presence of TA was not significant for the production of enzymes. The extract obtained using the enzymatic pool from MM medium showed the best results for gallic acid (43.89 ± 0.26 mg.100 g-1 dried GP) and the highest α-amylase inhibitory activity (97%). These results demonstrate the possibility of the synthesis of enzymes efficient in the recovery of phenolic compounds from GP without the need for very complex supplementation during SSF. |
