Ar. Gutierrez et al., ECOLOGY OF INOCULATED AND SPONTANEOUS FERMENTATIONS IN RIOJA (SPAIN) MUSTS, EXAMINED BY MITOCHONDRIAL-DNA RESTRICTION ANALYSIS, International journal of food microbiology, 36(2-3), 1997, pp. 241-245
Analysis of mitochondrial DNA restriction patterns was used to study t
ile introduction of a selected strain of Saccharomyces cerevisiae for
fermentation of non-sterile musts of La Rioja (Spain). All of the isol
ates from the inoculated musts showed the restriction pattern of the s
elected strain. The same technique was used to study the spontaneous f
ermentation of musts, showing that a few strains were responsible for
the fermentations. One of the strains identified from the spontaneous
fermentations had been identified in a previous vintage. (C) 1997 Else
