<p style="text-align: justify;"><strong>Aim</strong>: Grapes are submitted to several fungal attacks, which can impair quantity and quality of the resulting wine. The aim of this paper is to describe sets of primers that are able to easily characterise the strains isolated on the grapes by DNA sequencing.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Four sets of primers targeting the beta-tubulin and Internal Transcribed Spacer (ITS) regions were used. Samples were isolated from grey or green moulds on mature berries during 5 years in vineyards located in the Moselle Valley of Luxembourg. Identifications were performed by comparing the obtained sequences with referenced sequences using several databases. The isolates obtained from the grey mould were identified as <em>Botrytis cinerea</em>, <em>Mucor fragilis</em> and <em>Chaetomium globosum</em>, whereas on green mould, <em>Penicillium expansum</em>, <em>Penicillium minioluteum</em>, <em>Davidiella</em> <em>tassiana</em> and <em>Cladosporium cladosporioides</em> were recovered. Identification may be impossible for two reasons : samples may not display a sequence of sufficient quality, which can tentatively be solved by cloning the PCR amplicon, or databases may not be exhaustive enough to unambiguously determine the species. We therefore suggest primer sets for each species according to these limiting factors.</p><p style="text-align: justify;"><strong>Conclusion</strong>: The performances of the primers were species-dependent. Even though the ITS region is more highly represented in the databases than the beta-tubulin region, technical results were better for beta-tubulin sequences.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: This work provides a basic methodology for the molecular characterisation of the fungal flora encountered on grapes.</p>

Ozonation Process

The aim of this research was to show the effect of the ozonation process on the quality of sea buckthorn (Hippophae rhamnoides L.). The quality of the ozonated berries of sea buckthorn was assessed. Prior to and after the ozone treatment, a number of parameters, including the mechanical properties, moisture content, microbial load, content of bioactive compounds, and composition of volatile compounds, were determined. The influence of the ozonation process on the composition of volatile compounds and mechanical properties was demonstrated. The ozonation had negligible impact on the weight and moisture of the samples immediately following the treatment. Significant differences in water content were recorded after 7 days of storage. It was shown that the highest dose of ozone (concentration and process time) amounting to 100 ppm for 30 min significantly reduced the water loss. The microbiological analyses showed the effect of ozone on the total count of aerobic bacteria, yeast, and mold. The applied process conditions resulted in the reduction of the number of aerobic bacteria colonies by 3 log cfu g−1 compared to the control (non-ozonated) sample, whereas the number of yeast and mold colonies decreased by 1 log cfu g−1 after the application of 100 ppm ozone gas for 30 min. As a consequence, ozone treatment enhanced the plant quality and extended plant’s storage life.
