In this study, _Pediococcus_ spp. inhibited _O. oeni_ OT3. Discordant results concern the couple _L. hilgardii--O. oeni_, since [PERSON] et al. [83] observed that the growth of _O. oeni_ could be inhibited by means of H\({}_{2}\)O\({}_{2}\) produced by _L. hilgardii_ while, according to [PERSON] et al. [84], the inhibition of _O. oeni_ in co-culture with _L. hilgardii_ seems to be due to competition for arginine, a stimulating agent for the growth of _O. oeni_, and to the consumption of peptides by _L. hilgardii_. Interesting results of this study are referred to the different inhibitions between some LAB and non-_Saccharomyces_ yeasts. Specifically, _Pediococcus_ spp., _O. oeni_ OT3, and _O. oeni_ OT4 inhibited some strains of _M. pulcherrina_, _P. fermentatus_ B05A36, _P. fermentatus_ M105A30, and _T. delbrueckii_ 291. Furthermore, _O.
