Application of indigenous Saccharomycopsis fibuligera for light-flavor Baijiu fermentation: Changes of microbial community and flavor metabolism

Current Research in Food Science, Год журнала: 2025, Номер 10, С. 101008 - 101008

Ethyl acetate, a characteristic flavor compound in light-flavor Baijiu (LFB), plays pivotal role defining its sensory profile. Insufficient concentrations fermented grains may diminish the quality of Baijiu. Indigenous microbial bioaugmentation has proven effective improving by reshaping community and modulating metabolism within fermentation ecosystems. This study investigated effects Jiuqu fortified with an indigenous Saccharomycopsis fibuligera Y162 on community, physicochemical parameters, volatile profiles throughout LFB. Results demonstrated significant increase ethyl acetate content both original grains, alongside pronounced fungal restructuring. PacBio single-molecule real-time (SMRT) sequencing analysis showed that Lactobacillus helveticus, Rhizopus sp., Saccharomyces cerevisiae, Issatchenkia orientalis became dominant species at end fermentation. Correlation network revealed was significantly related (P < 0.05, |ρ| > 0.7) to I. sp. (the main biomarkers), which driven functional S. fibuligera. Mantel test further highlighted acidity, temperature, moisture as critical environmental factors influencing 0.7). To summarize, biofortification exhibited positive enhancing typical metabolites structure These findings imply strains have great application potential

Screening and identification of strains for high quality and antioxidant activity of Baijiu from strong-flavor Daqu and analysis of microbial synergistic effects

PLoS ONE, Год журнала: 2025, Номер 20(3), С. e0319616 - e0319616

Опубликована: Март 10, 2025

In this study, functional strains with strong fermentation characteristics were isolated from Strong-flavor Daqu and evaluated for their ability to enhance the quality antioxidant activity of Baijiu . Bacillus velezensis (S1), subtilis (S12), Escherichia coli (S16) identified as key strains. Fermentation experiments different inoculation amounts combinations revealed synergistic effects on activity. Specifically, total ester content in fermented 3% S1, S12 S16 increased by 5.68%, 53.41% 70.45% respectively, while DPPH radical scavenging rate was 52.01%, 17.63% 35.52%, compared only Multi-strain combinations, particularly 4%-S16+2.5%-S1 3%-S16+4%-S12, exhibited notable content. Furthermore, E. , 2% B. 4% combination significantly (1.94 g/L) (38.09%) which S1 The results GC-MS indicated that biofortified produced high levels esters guaiacol its analogues, facilitated interactions among indigenous microorganisms. This study is helpful provide a new perspective insight improving flavor

Beyond Saccharomyces: Exploring the Bioethanol Potential of Wickerhamomyces anomalus and Diutina rugosa in Xylose and Glucose Co-Fermentation

Fermentation, Год журнала: 2025, Номер 11(4), С. 204 - 204

Efficient co-fermentation of glucose and xylose remains a critical hurdle in second-generation bioethanol production. In this study, we evaluated two non-Saccharomyces yeasts—Wickerhamomyces anomalus UEMG-LF-Y2 Diutina rugosa UEMG-LF-Y4—under mixed-sugar conditions. D. exhibited superior metabolism ethanol productivity, achieving maximum volumetric productivity (QP) 0.55 g/L·h medium containing 20 g/L 40 xylose. Its highest yield (YP/S) reached 0.45 g EtOH/g sugar, comparable to results from engineered Saccharomyces cerevisiae strains. By contrast, W. displayed lower yields (0.24–0.34 g/g) greater sensitivity catabolite repression induced by 2-deoxyglucose (2-DG). Xylose consumption exceeded 80% high-xylose media, while left residual under all tested A strong inverse correlation (r < −0.98) between accumulation uptake was observed, especially for anomalus, indicating ethanol-induced inhibition as key challenge. These findings highlight the potential robust platform lignocellulosic processes, whereas may benefit further metabolic or process optimizations. Future research should address tolerance, inhibitory byproducts, large-scale feasibility fully exploit these strains
