Saccharomyces cereviseae in all traditional fermented drinks [60], Wickerhamomyces anomalus inchubitchi and wanti in Garo hills [42] were also identified. A metagenomic approach in xaj-pitha of Assam revealed the presence of fungi Mucor circinelloides, Rhizopus delemar and Aspergillus sp., budding yeast Wickerhamomyces ciferrii, Meyerozyma guilliermondii, and Debaryomyces hansenii, yeasts Dekkera bruxellensis and Ogataea parapolymorpha besides the dominance of LAB, like Lactobacillus plantarum, Lactobacillus brevis, Lactobacillus pseudomesenteroides, Leuconostoc lactis, Lactococcus lactis, Weissella paramesenteroides, and Weissella cibaria[11]. A study reported the isolation of Enterococcus sp. from fermented fish in Meghalaya [86], which produces bioactive compounds with antimicrobial properties [6].
Debaryomyces
Published in Dongyou Liu, Handbook of Foodborne Diseases, 2018
The genus Debaryomyces comprises generalist species of salt- and cold-tolerant ascomycetous yeasts able to colonize extreme environments, diverse ecological niches (e.g., soil, fruits, seawater, plants, insects, and air) and also the base of Arctic polythermal glaciers as well as a variety of fermented food products.1,2 The most representative species is Debaryomyces hansenii with its anamorph Candida famata. D. hansenii is extremophilic, due to its osmo-, xero-, and halo-tolerance, showing remarkable phenotypic plasticity and robust genotypes that allow it to persist in highly contrasting environments without needing to adapt to local conditions. D. hansenii is the most frequently encountered species of the genus in extreme cold, dry, salty, acidic, and deep-sea habitats.1–4
Candida

Since the Candida genus is integrated by asexual yeast species, several other genera have Candida anamorphs. Thus, some Candida anamorphs are frequently found in some food such as Debaryomyces hansenii (anamorph C. famata) or Kluyveromyces marxianus (anamorph C. kefyr). It should be noted that both species are used as commercial starter cultures and are included in the QPS (Qualified Presumption of Safety) list developed by the European Food Safety Authority (EFSA).23C. kefyr appears to be an emerging pathogen.3 Nevertheless, until now, there are no safety concerns about the use of K. marxianus because of the history of its apparent safe use and the rarity of its infections in human beings.24C. famata, found in food products such as cheese and meat products,12,18,25 has been associated with occasional infections.3,8,9,23–25

We applied sparse Partial Least Square Discriminant Analysis (sPLS-DA) to further investigate the mycobiome components driving the differences. The performance of our sPLS-DA model displayed an accuracy of 0.955 and we determined 16 and 4 discriminant taxa in component 1 and in component 2, respectively, of which 10 were significantly more abundant in controls and 3 in PWH (Figure 3, Figure S2, Table S1). We found that Debaryomyces hansenii (q-value = 3.29e-05), Candida albicans (q-value = 3.29e-05) and Candida parapsilosis (q-value = 3.29e-05) were the most abundant taxa in PWH, although their discriminant power (loading value in Figure 3a) was only moderate. In controls, the mycobiome was mainly characterized by four mold taxa and five yeasts. Among the molds, Kwoniella botswanensis (q-value = 1.35e-06) and Penicillium expansum q-value = 9.15e-05) showed the highest discriminant power, while the yeasts Malassezia restricta (ASV-0047, q-value = 3.2e-05 and ASV-0082, q-value = 1.36e-04), Rodothorula mucilaginosa (q-value = 4.55e-07), Pichia kluyveri (q-value = 3.00e-04), and Meyerozyma guilliermondii (q-value = 3.89e-04), had remarkable discriminative power in controls. Figure 3b shows the clustering of the samples on the base of the abundance of the differential ASVs determined by sPLS-DA.

Similar to gut virome, interactions among the bacterial microbiota, mycobiome, and gut immunity have been reported. Clusters IV and XIVa of Clostridia resist the colonization of Candida albicans via the hypoxia-inducible factor-1α-mediated generation of LL-37 in mice.42 The administration of anti-fungal agents exaggerated dextran sulfate sodium (DSS)-induced colitis and house dust mite-induced allergic airway disease, along with bacterial dysbiosis, including a decline in Bacteroides and Clostridium and an increase in Streptococcus.43 Unlike bacterial microbiota, fungal diversity changes moderately over time, with a slight increase in alpha-diversity while beta-diversity remains virtually unchanged.44 A transformation from Debaryomyces hansenii to Saccharomyces cerevisiae was evident in Saccharomycetales during the first year of life.44 Balanced mycobiota in adults mainly include Candida, Malassezia, and Saccharomyces.45

Tyrosol is another QSM that plays a role in stimulating germ tube, pseudohypha and biofilm formation in C. albicans (Sebaa et al. 2019) as well as showing antifungal activity against Candida spp. (Cordeiro et al. 2015), H. capsulatum and C. posadasii (Brilhante et al. 2016a). 2-Phenylethanol inhibits biofilm formation by Aspergillus fumigatus and Penicillium spp. (Liu et al. 2014; Wongsuk and Luplertlop 2020). Tryptophol regulates the germination of Aspergillus sp. and adhesion of Debaryomyces hansenii, and reduced the filament and virulence of Candida spp. in an in vivo model (Mehmood et al. 2019; Singkum et al. 2019). However, the effect of these QSMs on biofilm formation by Sporothrix spp. is not clearly understood.
