Sniffing the wine differences: The role of biofilm-detached cells.

This study investigated the impact of 10 strains of , co-inoculated as planktonic or biofilm-detached cells with , on the volatilome of a red wine. The wines produced with biofilm-detached cells exhibited a greater concentration of glycerol and a lower quantity of ethanol than the other wines. Furthermore, these wines exhibited elevated levels of higher alcohols, organic acids, esters, terpenes, and norisoprenoids.

Wine Barrel Biofilm as a Source of Yeasts with Non-Conventional Properties.

This study investigated the main microbial groups characterizing the interior surface of oak barrels from different years (1890, 1895, 1920, 1975, 2008) used in the production of vino cotto. The yeasts were characterized for the following properties: γ-aminobutyric acid (GABA) production, antioxidant activity, air-liquid interfacial biofilm formation, and anthocyanin adsorption capacity. Community-level physiological profile analysis revealed that the microbial communities inside the barrels used the tested carbon sources in different manners.

Contribution of and Oak Chips to Trebbiano d'Abruzzo Wine Volatile and Sensory Diversity.

In this study, six fermentation trials were carried out: co-inoculation and sequential inoculation of and in the presence and absence of oak chips. Moreover, strain was attached to the oak chips and co-inoculated or sequentially inoculated with . Wines fermented with adhered to oak chips showed a higher concentration of glycerol (more than 6 g/L) than the others (about 5 g/L).

Hypoxia and platelet lysate sustain differentiation of primary horse articular chondrocytes in xeno-free supplementation culture.

Currently, the main limitation for the use of adult differentiated chondrocytes in cell-based therapy and tissue engineering for the repair of articular cartilage is the difficulty of maintaining their state of differentiation during cell expansion. The adult articular cartilage has no direct blood supply, and local oxygen concentrations range from 5%-10% at the surface near the synovial fluid to less than 1% in the deep layer. Low oxygen tension is currently considered an important environmental condition for chondrocytes, and hypoxia has been explored as a signal potentially promoting differentiation and matrix deposition.

Impact of Saccharomyces cerevisiae and non-Saccharomyces yeasts to improve traditional sparkling wines production.

In this study the effect of a co-inoculum of S. cerevisiae (F6789) with Torulaspora delbrueckii (TB1) or Starmerella bacillaris (SB48) on the oenological and aroma characteristics of sparkling wines obtained with the Champenoise method was investigated. The autolytic outcome and the sensory profile of sparkling wines were also evaluated.

Impact of vineyard management on grape fungal community and Montepulciano d'Abruzzo wine quality.

In this study the effect of farming practices on the diversity of grape fungal community of Vitis vinifera L. cultivar Montepulciano and the microbial metabolic activity was investigated. Small-scale vinifications were performed and wines were characterized.

Promoting Candida zemplinina adhesion on oak chips: A strategy to enhance esters and glycerol content of Montepulciano d'Abruzzo organic wines.

In this study cell surface hydrophobicity and the ability to adhere on abiotic surfaces (polystyrene plates, stainless steel and oak chips) of 10 Candida zemplinina strains were assessed. Moreover, the impact of C. zemplinina cells adhered on oak surface on fermentation kinetics and volatile profile of Montepulciano d'Abruzzo organic wines was evaluated.

Lifestyle Modulates Wine Volatilome and Malolactic Fermentation Outcome.

In this study, nine strains were tested for their ability to adhere to polystyrene using mMRS and wine as culture media. Moreover, planktonic and biofilm-detached cells were investigated for their influence on malic acid degradation kinetics and aroma compound production. Three strains were able to adhere on polystyrene plates in a strain-dependent way.

Adhesion Properties, Biofilm Forming Potential, and Susceptibility to Disinfectants of Contaminant Wine Yeasts.

In this study, yeasts isolated from filter membranes used for the quality control of bottled wines were identified and tested for their resistance to some cleaning agents and potassium metabisulphite, adhesion to polystyrene and stainless-steel surfaces, and formation of a thin round biofilm, referred to as a MAT. A total of 40 strains were identified by rRNA internal transcribed spacer (ITS) restriction analysis and sequence analysis of D1/D2 domain of 26S rRNA gene. Strains belong to (12), (9), (1), (6), (3), (1), (2), (3), and (3) species.
