Hailong Li: Fungi and “the king of wines”: Impact of Botrytis cinerea infection on γ-nonalactone concentrations during botrytisation of noble rot wines
Listed in ZivaHub
<p dir="ltr">This research investigates the potential formation of γ-nonalactone during botrytisation, in the presence or absence of B. cinerea.
Description
Solid phase extraction (SPE) and gas chromatography-mass spectrometry (GC-MS) have been employed for the quantitative analysis of γ-nonalactone. In the preparation of Synthetic Grape Medium (SGM), sugar concentrations comparable to those of grape juice (21%), along with slightly lower (15%) and higher (28%) concentrations, were employed.
The effect of deep nobilisation by B. cinerea in SGM was evaluated by the baseline changes in fungal growth and potential γ-nonalactone production during the incubation period. The results show that the difference of fungal growth, pH change, sugar consumption are significant in different sugar concentrations. The growth of B. cinerea slowed the rise in pH but increased sugar consumption, although the overall changes were not very high.

The fungal growth rate was highest in the 15% sugar group, with a potentially elevated γ-nonalactone concentration detected in the GC-MS analysis. This work is expected to provide a controlled lab-based artificial noble rot method and to explore whether B. cinerea directly contributes to the biosynthesis of linear aliphatic lactones.</p>
