During the fermentation process, the dominant bacterial genera were\n                      <jats:italic>Ralstonia<\/jats:italic>\n                      and\n                      <jats:italic>Bacillus<\/jats:italic>\n                      , and the dominant fungal genera were\n                      <jats:italic>Aspergillus<\/jats:italic>\n                      ,\n                      <jats:italic>Issatchenkia<\/jats:italic>\n                      ,\n                      <jats:italic>Clavispora<\/jats:italic>\n                      , and\n                      <jats:italic>Zygosaccharomyces<\/jats:italic>\n                      . In addition, total acidity (TA) and amino acid nitrogen (AAN) in different fermentation stages were determined by the acidometer titration method, and reducing sugar (RS) was determined by the 3,5\u2010dinitrosalicylic acid method. The correlation network revealed TA, RS, and AAN were closely related to multiple microorganisms. TA showed significant positive correlations with\n                      <jats:italic>Gluconobacter<\/jats:italic>\n                      ,\n                      <jats:italic>Candida<\/jats:italic>\n                      , and\n                      <jats:italic>Clavispora<\/jats:italic>\n                      . RS was positively correlated with\n                      <jats:italic>Geotrichum<\/jats:italic>\n                      , and AAN was positively correlated with\n                      <jats:italic>Methylobacterium\u2010Methylorubrum<\/jats:italic>\n                      and\n                      <jats:italic>Zygosaccharomyces<\/jats:italic>\n                      . Correlation network analysis was also conducted to show the significant correlations among 2 bacterial genera, 9 fungal genera, and 16 characteristic volatile compounds. In general, the relationships between fungus and volatiles were more significant, with a wide range of yeasts exerting significant functions in forming flavor compounds, whereas most bacteria were negatively correlated with volatiles. Among fungi,\n                      <jats:italic>Clavispora<\/jats:italic>\n                      and\n                      <jats:italic>Meyerozyma<\/jats:italic>\n                      were positively associated with furfural, methional, 5\u2010methyl\u20102\u2010phenyl\u20102\u2010hexenal, 2\u2010isopropyl\u20105\u2010methylhex\u20102\u2010enal, and benzeneacetaldehyde.\n                      <jats:italic>Zygosaccharomyces<\/jats:italic>\n                      exhibited strong correlations with acetic acid, 2\u2010furanmethanol, phenylethyl alcohol, and 2\u2010methyl\u20101\u2010butanol.
