Abstract: The number of killer, neutral and sensitive yeasts was determined from strains isolated from substrates related to alcoholic fermentations. From 113 isolates, 24 showed killer activity against NCYC 1006 (standard sensitive strain), while 30 were sensitive to NCYC 738 (standard killer strain), and 59 had no reaction in assays at 25-27°C. Two wild yeast strains of Saccharomyces cerevisiae and one of Candida colliculosa were tested against 10 standard killer strains and one standard sensitive strain in a cell x c… Show more

“…Two strains of S. cerevisiae isolated from an ethanol fermentation plant and exhibiting rough colonies and pseudohyphal morphology similarly displayed a neutral reaction to a group of standard killer strains at several pH values (Ceccato-Antonini et al , 1999). A study of 165 flocculent yeasts found that only 3% were killer toxin producers (Steckelberg and Andrietta, 2011).…”

“…The yeasts were also evaluated for production of killer toxins, but none of the strains, regardless of whether they formed smooth or rough colonies, produced killer toxins that inhibited the sensitive yeast strains under the conditions utilised in this study (data not shown).

“…The commercial brand of yeast did not show any kind of killer activity in any experiment. The killer system was the most important and decisive factor for the yeasts to establish during the fermentative process, since there were many yeast strains presenting neutral phenotype, as already showed for some wild yeasts presenting pseudohyphal morphology (Ceccato-Antonini et al, 1999). The point is not only to show a killer phenotype, but to express this killing action during the fermentation process, in industrial scale, under limiting conditions presented by the culture medium and environmental conditions.…”

“…This is due to the non-chromosomal killer genom loss or mutation (Wickner, 1974). The occurrence of killer phenotype in yeasts is widespread in alcoholic fermentations for beverage production such as in breweries (Maule and Thomas, 1973), saké (Imamura et al, 1974;Ouchi et al, 1979), wine (Naumov et al, 1973;Thornton, 1986;Petering et al, 1991;Sulo and Michalcáková, 1992;Carrau et al, 1993) and recently in sugarcane producing plants (Sato et al, 1993;Morais et al, 1997;Ceccato-Antonini et al, 1999;Sato, 1999, 2000). Many of these fermentative processes use non-pasteurised medium, which can allow the predominance of wild yeast strains coming from the raw material outnumbering the starter yeast.…”
