Commercial pectolytic enzymes play an important role in the winemaking process. PE (pectinesterase) can catalysis the de-esterification reaction、the methyl ester group on the C6 carboxyl of D- galacturonic acid in the pectin could be hydrolyzed by PE to produce the free carboxyl group and the methanol、and the methanol is harmful to human body. Affinity chromatography re-esterification CL-AIS can separate PL from commercial pectolytic enzymes、but it was hard to separate PG (polygalacturonase) from PE. In winemaking、Black queen grape was used as the raw material in this study、and it was fermented with commercial yeast RA-17 (S. cerevisiar). Commercial pectolytic enzymes、commercial pectolytic enzymes without PL and PL were added in grape winemaking individually、Lab value、pH value、%T、titrable acidity(%)、toatal soluble solids(°Brix)、methanol and alcohol content were detected during the procedure of winemaking. The methanol content in the sample added with commercial pectolytic enzymes was 3102ppm (based on ethanol content) and the methanol content was only 563ppm as the PL enzyme was added only. The result showed that the PL (pectin lyase) enzyme used in the winemaking could reduce the methanol content and the must was clear、so、the development of PL enzyme is promising for the clarification and reducing the content of the methanol in fruit juice and wine in the future.

Full textThe study of this master's thesis, aims to compare in four of claret winemaking from a common initial mash. What is the influence that the inoculation of yeasts prepared industrially, the application of pectolytic enzymes or both together, would have in the final product, compared to the control winemaking only with the indigenous yeasts and enzymes. We present results of the physicochemical analysis carried out to the four wines, in two different periods in time. Also in both periods we present the results of sensory analysis, realised to the four samples (blind test), by a group of wine tasters according with a grid previously stipulated. The results obtained, suggests that there are no significant differences regarding the parameters of the physicochemical analysis, but we found in the parameters: procianidinas, proantocianidinas, some anthocyanins, color, tone and condensed tannins. In the sensory analysis, the wine tasters, also found some differences that are presented in this study.-------------------------------------O ensaio realizado nesta tese de mestrado, visa comparar em quatro vinificações de vinho tinto em lagar a partir dum mosto inicial comum. Qual a influência que a inoculação de leveduras preparados industrialmente, a aplicação de enzimas pectolíticas ou ambas em conjunto, teriam no produto final, comparativamente ao vinho testemunha vinificado apenas com as leveduras e enzimas autóctones. Apresentam-se os resultados das análises físico químicas realizadas aos quatro vinhos, algumas em dois diferentes períodos no tempo. Também de dois períodos se apresentam os resultados de análise sensorial, realizada por prova cega às quatro amostras, por um grupo de provadores segundo uma ficha de prova estipulada previamente. Os resultados obtidos para as condições do ensaio, permitem concluir que não se encontraram diferenças significativas quanto aos parâmetros da análise corrente sumária, mas pelo contrário detectaram-se nos parâmetros procianidinas, proantocianidinas, algumas antocianinas, cor, tonalidade e taninos condensados. Na análise sensorial, também os provadores encontraram algumas diferenças que são neste trabalho apresentados.

Pectinesterase (PE) will hydrolyze the methoxyl groups in the galacturonic acids of pectin to release methanol and the degree of esterification will be decreasing. Recent researches indicated that transacylation reaction occurred simultaneously when the de-esterification reaction progressed by PE through the analysis of gel permeation chromatography, viscometer and Instron etc.. The PE catalyzed the transacylation, and the new forms of ester linkages between pectin molecules also will be illustrated, and the increscent in the molecular weight of pectin in the presence of PE during incubation. Results showed that PE from Aspergillus niger remarkably conducted the transacylation that was affected by some factors, the optimal conditions for transacylation by Aspergillus niger PE were 40 ℃ and at pH 3.0~3.35 by laser particle size analysis. The transacylation catalyzed by PE from Aspergillus niger is not showed positive relation to it’s enzyme activity, the range of particle size is wide in pH 3.35 and 3.0, the pH value plays an important role in transacylation reaction.

Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), is one of the most destructive diseases of citrus. The pectolytic enzymes produced by phytobacteria are important virulence factors involved in tissue maceration, electrolyte loss and cell death of host plants. In this study, the promoter activity of the pectolytic enzyme genes pel1, pel2, pel3, pglA, and peh-1 were investigated in Xcc strain XW19 using the β-glucuronidase (GUS) gene as a reporter, and the function of pel1, pel3, pglA, and peh-1 were investigated using the gene deletion mutagenesis. GUS activity expressed under the control of the pel1, pel3, pglA, and peh-1 gene promoters positively correlated with bacterial growth, and displayed high GUS activity in the presence of sodium polypectate and induced in XVM2 medium and host plant. However, only pel1 was subjected to catabolite repression by glucose. GUS activity was significantly enhanced in the XW19-derived reporter strains after they were inoculated into the leaves of Mexican lime and grapefruit, suggesting the involvement of the pel1, pel3, pglA, and peh-1 genes in XW19 pathogenesis. The pel3 promoter produced the highest GUS activity under all test conditions, whereas no GUS activity was detected using the pel2 promoter in vitro and in planta. In comparison with wild type XW19, the canker lesions elicited by the pel1, pglA or peh-1 mutant was the same on the leaves of Mexican lime and grapefruit. Although, the pel3 mutant displayed reduced growth and induced smaller canker lesions on the leaves of Mexican lime or grapefruit compared with the wild type XW19, we demonstrate that Pel3 of Xcc strain XW19 is a virulence factor, and affects the canker elicitation and bacterial growth in host plant. In addition, the PacBio RSII sequencing platform were used to obtain a complete sequence of Xcc strain XW121, an Ar pathogenic variant in Taiwan. Based on RAST analysis, Xcc strain XW121 was closeset the Xcc strain 306, and has a single, circular chromosome and 2 plasmids. The genome size is 5,299,054 bp and the G+C content averages 64.7%. The Xcc strain XW121 genome contains 3,236 putative CDSs, 2 rRNA operons, and 54 tRNAs. The contig_3 and contig_4 share 99% identity with pXAC64 and pXAC33, respectively. The CDSs within Xcc strain XW121 genome has fewer CDSs than strain 306, and the difference between them need to be further confirmed. Xcc strain XW121 has avrXacE3 homolog gene but not avrGf1 homolog gene. The predicted sequence of pthA1, pthA2, pthA3, and pthA4 genes is low identities with Xcc strain 306 and can not translate complete protein, demonstrating that it affects the weaker virulence of Xcc strain XW121.
