Chitosan elicits mono-glucosylated stilbene production and release in fed-batch fermentation of grape cells 


In the present study, the optimal conditions of grape (Vitis vinifera cv ‘Barbera’) cell cultures in batch and fed-batch bioreactor processes were studied to specifically improve the production of mono-glucosylated stilbenes. With respect to jars, bioreactor system induced higher polyphenol yields and largely increased their release in the culture medium. The highest stilbene production was reached in fed-batch bioreactor process supplied with 50 mg L-1 chitosan, that improved the accumulation of both free and mono-glucosylated resveratrol derivatives. Moreover, the vast majority of the compounds was released in the culture media, this being a considerable advantage for the bioreactor production and easier recovery of specific molecules or of polyphenol enriched mixtures as a promising alternative to whole plant extraction.

Investigation of VvDXS function and its effects on muscat flavor levels

In the present study the connection between the positional candidate gene VvDXS and muscat flavor was evaluated by investigating the expression profiles in the berries from a Muscat-type cultivar and a neutral cultivar and its nucleotide diversity of full ORF on grapevine accessions.

Optimization of aroma production in grape cell suspensions induced by chemical elicitor

Methyl-jasmonate (MeJA) induces the production of at least 25 compounds with sesquiterpene- like mass spectra in ‘Cabernet sauvignon’. Tost effective concentration of MeJA in stimulating the production of sesquiterpenes was found to be 500 µM if added when the cell suspensions had a PCV of 35 %, and 1000 if added when the cell suspensions had a PCV of 70 %.

Seed phenolics oxidation: development of a new ripening index 

During ripening seed tannins evolve, as demonstrated by the taste and color changes. In this work we tried to develop an objective, easy and fast index, useful for winemakers. In this direction we propose two different spectrophotometric indexes, one related to the molecular structure and tannin subunits linkages, and the other related to the antioxidant properties. Especially the second one gave very interesting and unexpected results.

Aroma accumulation trends during berry development and selection of grape aroma candidate genes suitable for functional characterization

Grape flavour management in the vineyard requires knowledge of the derivation of individual flavour and aroma characteristics and the effects that different concentrations and interactions between these compounds have on flavour potential.
