Origem e disseminação dos microrganismos do vinho
| Resumo: | During the production of wine, various microorganisms may be involved such as yeasts, lactic acid bacteria and acetic acid bacteria. However, although there is a vast amount of information on the microorganisms that belong to the wine microbial consortium, its origin and persistence in environment close to the vineyard, through the year, has not be unraveled, yet. The aim of this study was to evaluate the microbial diversity associated with vineyard’s environments, through the year, to understand consortium microorganisms’ spread and prevalence. Soils, bark trees, insects, grapevine leaves, grapes, must and cellar equipment were analyzed. The isolated microorganisms were submitted to phenotypic tests and according to the results were selected to molecular identification. Therefore, it was noted that, in these environments, the consortium microorganisms’ prevalence was very low. Consequently, these microorganisms were only found on trees, insects, soils and damaged grapes. Nonetheless, in must and cellar equipment most of the isolated microorganisms belonged to wine microbial consortium. Thus, it remains to find which are the reservoirs preferred by wine consortium microorganisms |
