“…divulgata was mainly detected in the March batch and its presence is quite unusual in this type of product in contrast to other Yarrowia spp., that is, Y. deformans and Y. lipolytica which have been previously reported in salami products (Aquilanti et al 2007;Belleggia et al 2020b). The latter species is a widely reported as a spoilage agent of dairy and meat products but, at the same time, it can exert beneficial effects during the ripening of various cheeses and meat products and contributes to their organoleptic properties by aroma compound production (Nagy et al 2013;P eter and Nagy 2019). Y. divulgata, which was originally described and isolated from meat products (Nagy et al 2013), may have an undesirable effect on the product as this species is capable of producing high amounts of sweetener molecules, that is erythritol and mannitol from glycerol (Rakicka et al 2016; P eter and Nagy 2019) with production rates higher than that of Y. lipolytica (Rakicka et al 2016).…”

Aims: The complex mycobiota that colonizes traditional fermented sausages plays an important role in the organoleptic properties of such products. The aim of the present study was to investigate fungal diversity and mycotoxin production during maturation of PGI Salame Piemonte.Methods and Results: Casing and meat samples were collected at five sampling times from three different batches produced in the same factory and analysed using culture-dependent and -independent approaches. Penicillium nalgiovense, which was deliberately inoculated, and Debaryomyces hansenii, were the most dominant taxa in casings. Several other fungi mainly belonging to Penicillium crustosum, P. glabrum, P. nordicum, Cladosporium spp., Candida sake, C. zeylanoides and Yarrowia divulgata were also identified.The casing mycobiota was compared to that of the meat using a metataxonomic approach and a higher fungal diversity was observed in meat as compared to casings. Mycotoxins and penicillin G were monitored using QTOF LC-MS and only trace amounts of roquefortine C were detected in two batches.Conclusions: The present study highlighted the diversity of Salame Piemonte mycobiota and the important contribution of autochthonous fungi to its diversity. The absence of mycotoxins and penicillin G confirmed the high hygienic quality of the studied product regarding fungal and mycotoxin contamination.Significance and Impact of Study: For the first time, this study provides insights about the Salame Piemonte mycobiota which together with the bacterial microbiota and Salame Piemonte process specifications are responsible for the product organoleptic properties.

“…For example, while most Komagataella species have been isolated from broad‐leaved trees, Komagataella kurtzmanii has been isolated only from fir flux. Additionally, K. pseudopastoris has higher sensitivity to the tannic acids in Quercus species than K. pastoris (Dlauchy et al, 2003; Péter et al, 2019).…”

Yeasts are ubiquitous in temperate forests. While this broad habitat is well‐defined, the yeasts inhabiting it and their life cycles, niches, and contributions to ecosystem functioning are less understood. Yeasts are present on nearly all sampled substrates in temperate forests worldwide. They associate with soils, macroorganisms, and other habitats and no doubt contribute to broader ecosystem‐wide processes. Researchers have gathered information leading to hypotheses about yeasts' niches and their life cycles based on physiological observations in the laboratory as well as genomic analyses, but the challenge remains to test these hypotheses in the forests themselves. Here, we summarize the habitat and global patterns of yeast diversity, give some information on a handful of well‐studied temperate forest yeast genera, discuss the various strategies to isolate forest yeasts, and explain temperate forest yeasts' contributions to biotechnology. We close with a summary of the many future directions and outstanding questions facing researchers in temperate forest yeast ecology. Yeasts present an exciting opportunity to better understand the hidden world of microbial ecology in this threatened and global habitat.

“…Since then, numerous species have been assigned to the Yarrowia clade primarily based on marker sequencing, which has become a common tool in taxonomic studies. Today, the Yarrowia clade comprises Y. lipolytica , Yarrowia alimentaria , Yarrowia bubula , Yarrowia brassicae , Yarrowia deformans , Yarrowia divulgata , Y. galli , Yarrowia hollandica , Yarrowia keelungensis , Yarrowia osloensis , Yarrowia parophonii , Yarrowia phangngaensis , Yarrowia porcina , Yarrowia yakushimensis , and C. hispaniensis [ 5 ]. The species listed above share many morphological and physiological characteristics of Y. lipolytica.…”

Proteolytic enzymes are commercially valuable and have multiple applications in various industrial sectors. The most studied proteolytic enzymes produced by Yarrowia lipolytica, extracellular alkaline protease (Aep) and extracellular acid protease (Axp), were shown to be good candidates for different biotechnological applications. In this study, we performed a comprehensive analysis of the alkaline proteolytic enzymes of Yarrowia clade species, including phylogenetic studies, synteny analysis, and protease production and application. Using a combination of comparative genomics approaches based on sequence similarity, synteny conservation, and phylogeny, we reconstructed the evolutionary scenario of the XPR2 gene for species of the Yarrowia clade. Furthermore, except for the proteolytic activity of the analyzed Yarrowia clade strains, the brewers’ spent grain (BSG) was used as a substrate to obtain protein hydrolysates with antioxidant activity. For each culture, the degree of hydrolysis was calculated. The most efficient protein hydrolysis was observed in the cultures of Y. lipolytica, Y. galli, and Y. alimentaria. In contrast, the best results obtained using the 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) method were observed for the culture medium after the growth of Y. divulgata, Y. galli, and Y. lipolytica on BSG.
