However, the dynamic alterations of microbiota and volatile compounds of Douchiba were seldom reported. In this work, the bacterial communities and volatile compounds during the fermentation process of Douchiba were explored by high\u2010throughput sequencing and headspace solid\u2010phase microextraction and gas chromatography\u2013mass spectrometry (HS\u2010SPME\u2010GC\u2010MS) techniques, respectively. Furthermore, the correlation between microbial communities and volatile compounds was analyzed with Spearman's method. The findings revealed that the diversity and evenness of bacteria increased during the fermentation process of Douchiba. The dominant bacteria genera included\n                    <jats:italic>Bacillus<\/jats:italic>\n                    ,\n                    <jats:italic>Staphylococcus<\/jats:italic>\n                    ,\n                    <jats:italic>Tetragenococcus<\/jats:italic>\n                    ,\n                    <jats:italic>Loigolactobacillus<\/jats:italic>\n                    , and\n                    <jats:italic>Virgibacillus<\/jats:italic>\n                    .\n                    <jats:italic>Bacillus<\/jats:italic>\n                    dominated the bacterial communities throughout the fermentation process, and\n                    <jats:italic>Staphylococcus<\/jats:italic>\n                    ,\n                    <jats:italic>Tetragenococcus<\/jats:italic>\n                    ,\n                    <jats:italic>Loigolactobacillus<\/jats:italic>\n                    , and\n                    <jats:italic>Virgibacillus<\/jats:italic>\n                    also became the dominant genera in the fermentation and after\u2010ripening stages. A total of 134 volatiles were identified. The main volatiles were ketones and alcohols in the koji\u2010making stage, ketones and pyrazines in the fermentation stage, and acids in the after\u2010ripening stage. In total, 26 compounds were selected as the main characteristic volatiles, including 2,3,5\u2010trimethylpyrazine, 3\u2010methyl\u20101\u2010butanol, and indole, which endowed Douchiba with a specific flavor. Additionally,\n                    <jats:italic>Bacillus<\/jats:italic>\n                    was significantly positively correlated with isovaleraldehyde, benzaldehyde, and acetic acid.\n                    <jats:italic>Staphylococcus<\/jats:italic>\n                    was significantly positively correlated with indole, 3\u2010methylbutanoic acid, and eucalyptol.\n                    <jats:italic>Tetragenococcus<\/jats:italic>\n                    ,\n                    <jats:italic>Loigolactobacillus<\/jats:italic>\n                    , and\n                    <jats:italic>Virgibacillus<\/jats:italic>\n                    were significantly correlated with indole and estragole.
