The thermovinification technique, as a replacement for traditional maceration, is primarily applied to increase the extraction of phenolic compounds and may impact the yeast growth dynamics during alcoholic fermentation, affecting the quality of red wine. Concurrently, the use of indigenous yeasts is currently proposed as an alternative to promote greater aroma complexity and typicity of the wine. The objective of this study was to evaluate the combined effect of thermovinification and the use of indigenous yeasts on the fermentative kinetics and metabolomic profile of Syrah red wine must. The yeasts were isolated from Syrah grapes from the Sub-middle Sao Francisco Valley region, Brazil. The tested yeast strains were: commercial Saccharomyces cerevisiae MaurivinPDM®(PDM); indigenous Saccharomyces cerevisiae yeast(SC); and the combination of indigenous yeasts Hansenispora opuntiae and Saccharomyces cerevisiae(HO+SC). The wines were vinified using maceration during the fermentation for 7 days (traditional method) and thermovinification (65°C, 2h), totaling six treatments. Throughout fermentation, quantification of sugars, alcohols, and organic acids was performed using chromatography (HPLC/DAD/RID), as well as the cell viability analysis, biomass, soluble solids, pH, total acidity, and density. Thermovinification increased the cell viability of indigenous yeasts, promoted higher substrate consumption rates and product formation (ethanol), improving the productivity and yield of the fermentation process, and also increasing the levels of organic acids. The combination of the thermovinification technique with the use of isolated indigenous yeasts can be recommended for the production of Syrah red wine in the Sub-middle Sao Francisco Valley region as an alternative to strengthen the recently obtained Geographical Indication for the region. Future studies should investigate the impact of thermovinification technique and indigenous yeasts on the profile of other metabolites, such as phenolic and volatile compounds.

The aim of the present study was to verify associations between reproductive efficiency and four microsatellite markers located in synteny with genes involved in the regulation of reproductive mechanisms. A sample of 107 females from a Brangus Ibagé population (5/8 Aberdeen Angus x 3/8 Nelore) was characterized for ETH225 (D9S1) and MM12E6 (D9S20) microsatellites, mapped on chromosome 9, and HEL5 (D21S15) and AFZ1 (D21S37) on chromosome 21. Associations between the genetic markers and reproductive efficiency were determined by one-way analysis of variance using calving interval (CI), live weight at calving (LWC), live weight at first calving (LW1C) and live weight at second calving (LW2C) as dependent variables. The genotypes were classified according to allele size into homozygous for long alleles, homozygous for short alleles and heterozygous. A longer CI was observed for individuals homozygous for long alleles at the HEL5 locus compared with the others (p = 0.022). For the AFZ1 locus, an inverse correlation between allele size and calving interval was observed (p = 0.022), suggesting that homozygosity for long alleles at this microsatellite could be advantageous. Analysis of the combined effect of favorable genotypes at HEL5 and AFZ1 indicated that animals with unfavorable genotypes (homozygous for long alleles at HEL5 and homozygous for short alleles at AFZ1) presented a significantly longer CI (p = 0.003) when compared to the other genotypes. The ETH225 and MM12E6 systems did not present any association with CI. None of the systems studied showed any significant association with LWC, LW1C or LW2C.
