Abstract
Introduction Folate supplementation is crucial for the human body, and the chemically synthesized folic acid might have undesirable side effects. The use of molecular breeding methods to modify the genes related to the biosynthesis of folate by probiotics to increase folate production is currently a focus of research. Methods In this study, the folate-producing strain of Limosilactobacillus reuteri B1-28 was isolated from human breast milk, and the difference between B1-28 and folA gene deletion strain ΔFolA was investigated by phenotyping, in vitro probiotic evaluation, metabolism and transcriptome analysis. Results The results showed that the folate producted by the ΔFolA was 2-3 folds that of the B1-28. Scanning electron microscope showed that ΔFolA had rougher surface, and the acid-producing capacity (p = 0.0008) and adhesion properties (p = 0.0096) were significantly enhanced than B1-28. Transcriptomic analysis revealed that differentially expressed genes were mainly involved in three pathways, among which the biosynthesis of ribosome and aminoacyl-tRNA occurred in the key metabolic pathways. Metabolomics analysis showed that folA affected 5 metabolic pathways, involving 89 different metabolites. Discussion In conclusion, the editing of a key gene of folA in folate biosynthesis pathway provides a feasible pathway to improve folate biosynthesis in breast milk-derived probiotics.

Abstract
Chromosome aneuploidy is a common phenomenon in industrial yeast. Aneuploidy is considered one of the strategies to enhance the industrial properties of Saccharomyces cerevisiae strains. However, the effects of chromosomal aneuploidy on the brewing properties of sake have not been extensively studied. In this study, sake brewing was performed using a series of genome-wide segmental duplicated laboratory S. cerevisiae strains, and the effects of each segmentally duplicated region on sake brewing were investigated. We found that the duplication of specific chromosomal regions affected the production of organic acids and aromatic compounds in sake brewing. As organic acids significantly influence the taste of sake, we focused on the segmental duplication of chromosome II that alters malate levels. Sake yeast Kyokai No. 901 strains with segmental chromosome II duplication were constructed using a polymerase chain reaction-mediated chromosomal duplication method, and sake was brewed using the resultant aneuploid sake yeast strains. The results showed the possibility of developing sake yeast strains exhibiting low malate production without affecting ethanol production capacity. Our study revealed that aneuploidy in yeast alters the brewing properties; in particular, the aneuploidy of chromosome II alters malate production in sake brewing. In conclusion, aneuploidization can be a novel and useful tool to breed sake yeast strains with improved traits, possessing industrial significance.

Abstract
Brazil is the largest producer of oranges worldwide, as well as one of the largest producers of orange juice. Alcoholic fermented beverages have been considered a marketable alternative for oranges. In this study, four S. cerevisiae commercial yeasts were evaluated for metabolites generated during orange juice (cv. 'Pêra D9') fermentation. Alcohols, sugars, and organic acids were evaluated by HPLC-DAD-RID during fermentation, and phenolic compounds were analyzed in fermented orange. Orange juice and fermented oranges were also subjected to digestion simulations. The yeasts presented an adequate fermentation activity, based on sugar consumption, and high ethanol (>10.5%) and glycerol (4.8-5.5 g/L) contents. The yeast strains T-58 and US-05 produced high levels of lactic acid. Phenolic compounds and antioxidant activity did not differ amongst yeasts, presenting hesperidin levels between 115 and 127 mg/L, respectively. The fermented orange showed a >70% bioaccessibility, compared to juice, especially for catechin, epigallocatechin-gallate, procyanidin-B2, rutin, and procyanidin-B1.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-aged women. Recently, various dietary interventions have been used extensively as a novel therapy against PCOS. In the present study, we show that soy isoflavone metabolites and resistant starch, together with gut microbiota modulations, were successful in decreasing the severity of PCOS-like reproductive features while increasing the expression of gut barrier markers and butyric acid in the gut. In the letrozole-induced PCOS model rats, the intake of both 0.05% soy isoflavones and 11% resistant starch, even with letrozole treatment, reduced the severity of menstrual irregularity and polycystic ovaries with a high concentration of soy isoflavones and equol in plasma. Antibiotic cocktail treatment suppressed soy isoflavone metabolism in the gut and showed no considerable effects on reducing the PCOS-like symptoms. The mRNA expression level of occludin significantly increased with soy isoflavone and resistant starch combined treatment. Bacterial genera such as Blautia, Dorea and Clostridium were positively correlated with menstrual irregularity under resistant starch intake. Moreover, the concentration of butyric acid was elevated by resistant starch intake. In conclusion, we propose that both dietary interventions and gut microbiota modulations could be effectively used in reducing the severity of PCOS reproductive features.

Abstract
Sake yeast is one of the important factors that characterize the aroma and taste of sake. To obtain sake yeast strains with different metabolic capabilities from other strains, breeding of a sake yeast is an effective way. In this study, sake yeast strain Y5201 was mutagenized by synchrotron light irradiation to obtain the mutant strains showing different brewing characteristics from parental strain Y5201, and comparative genome analysis between strain Y5201 and mutant strains was performed to identify mutation points and patterns induced by synchrotron light irradiation. Screening with the drug-resistant and fermentation tests selected the nine mutants (C18, C19, C29, C50, C51, C52, C54, T25, and T49) from the mutagenized Y5201 cells. Principal component analysis results based on the analysis of the small-scale brewing test metabolites showed that the mutant strain C19 was different from other strains, which had higher productivity of ethyl caproate and isoamyl acetate than those of the Y5201. Comparative genome analysis revealed that mutants by synchrotron light irradiation had a higher diversity of single nucleotide substitutions and a higher frequency of Indel (insertion/deletion) in these DNA than ethyl methanesulfonate and UV irradiation. These results suggest that synchrotron light irradiation is an effective and unique mutagen for yeast breeding.

Abstract
Despite the advantages of continuous fermentation whereby ethanol is selectively removed from the fermenting broth to reduce the end-product inhibition, this process can concentrate minor secondary products to the point where they become toxic to the yeast. This study aims to develop a new mathematical model do describe the inhibitory effect of byproducts on alcoholic fermentation including glycerol, lactic acid, acetic acid, and succinic acid, which were reported as major byproducts during batch alcoholic fermentation. The accumulation of these byproducts during the different stages of batch fermentation has been quantified. The yields of total byproducts, glycerol, acetic acid, and succinic acid per gram of glucose were 0.0442, 0.023, 0.0155, and 0.0054, respectively. It was found that the concentration of these byproducts linearly increases with the increase in glucose concentration in the range of 25-250 g/L. The results have also showed that byproduct concentration has a significant inhibitory effect on specific growth coefficient (μ) whereas no effect was observed on the half-velocity constant (K s). A new mathematical model of alcoholic fermentation was developed considering the byproduct inhibitory effect, which showed a good performance and more accuracy compared to the classical Monod model.

Abstract
Although Saccharomyces cerevisiae and S. cerevisiae var. boulardii share more than 95% genome sequence homology, only S. cerevisiae var. boulardii displays probiotic activity. In this study, the transcriptomic differences exhibited by S. cerevisiae and S. cerevisiae var. boulardii in intestinal like medium were evaluated. S. cerevisiae was found to display stress response overexpression, consistent with higher ability of S. cerevisiae var. boulardii to survive within the human host, while S. cerevisiae var. boulardii exhibited transcriptional patterns associated with probiotic activity, suggesting increased acetate biosynthesis. Resorting to the creation of a S. cerevisiae var. boulardii genomic database within Yeastract+, a possible correlation between loss or gain of transcription factor binding sites in S. cerevisiae var. boulardii promoters and the transcriptomic pattern is discussed. This study suggests that S. cerevisiae var. boulardii probiotic activity, when compared to S. cerevisiae, relies, at least partially, on differential expression regulation, based on promoter variability.

Unique genetic basis of the distinct antibiotic potency of high acetic acid production in the probiotic yeast Saccharomyces cerevisiae var. boulardii. Genome Res 2020; 29:1478-1494. [PMID: 31467028 PMCID: PMC6724677 DOI: 10.1101/gr.243147.118] [Citation(s) in RCA: 39] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Accepted: 06/20/2019] [Indexed: 12/14/2022]
Abstract
The yeast Saccharomyces boulardii has been used worldwide as a popular, commercial probiotic, but the basis of its probiotic action remains obscure. It is considered conspecific with budding yeast Saccharomyces cerevisiae, which is generally used in classical food applications. They have an almost identical genome sequence, making the genetic basis of probiotic potency in S. boulardii puzzling. We now show that S. boulardii produces at 37°C unusually high levels of acetic acid, which is strongly inhibitory to bacterial growth in agar-well diffusion assays and could be vital for its unique application as a probiotic among yeasts. Using pooled-segregant whole-genome sequence analysis with S. boulardii and S. cerevisiae parent strains, we succeeded in mapping the underlying QTLs and identified mutant alleles of SDH1 and WHI2 as the causative alleles. Both genes contain a SNP unique to S. boulardii (sdh1F317Y and whi2S287*) and are fully responsible for its high acetic acid production. S. boulardii strains show different levels of acetic acid production, depending on the copy number of the whi2S287* allele. Our results offer the first molecular explanation as to why S. boulardii could exert probiotic action as opposed to S. cerevisiae. They reveal for the first time the molecular-genetic basis of a probiotic action-related trait in S. boulardii and show that antibacterial potency of a probiotic microorganism can be due to strain-specific mutations within the same species. We suggest that acquisition of antibacterial activity through medium acidification offered a selective advantage to S. boulardii in its ecological niche and for its application as a probiotic.

Abstract
Characterizing a protein's function often requires a description of the cellular state in its absence. Multiplexing in mass spectrometry-based proteomics has now achieved the ability to globally measure protein expression levels in yeast from 10 cell states simultaneously. We applied this approach to quantify expression differences in wild type and nine deubiquitylating enzyme (DUB) knockout strains with the goal of creating "information networks" that might provide deeper, mechanistic insights into a protein's biological role. In total, more than 3700 proteins were quantified with high reproducibility across three biological replicates (30 samples in all). DUB mutants demonstrated different proteomics profiles, consistent with distinct roles for each family member. These included differences in total ubiquitin levels and specific chain linkages. Moreover, specific expression changes suggested novel functions for several DUB family members. For instance, the ubp3Δ mutant showed large expression changes for members of the cytochrome C oxidase complex, consistent with a role for Ubp3 in mitochondrial regulation. Several DUBs also showed broad expression changes for phosphate transporters as well as other components of the inorganic phosphate signaling pathway, suggesting a role for these DUBs in regulating phosphate metabolism. These data highlight the potential of multiplexed proteome-wide analyses for biological investigation and provide a framework for further study of the DUB family. Our methods are readily applicable to the entire collection of yeast deletion mutants and may help facilitate systematic analysis of yeast and other organisms.
