Project description:MS/MS data from a study investigating the impact of cultivation time on the metabolites of an Aspergillus brasiliensis cultivation in guabiju, using untargeted metabolomics.
Project description:<p>Black aspergilli exhibit remarkable bioconversion potential by transforming plant matrices into bioactive compounds, although their metabolic processes remain underexplored. This study investigated the biotransformation of metabolites during the solid-state cultivation of guabiju (<em>Myrcianthes pungens</em>) by <em>Aspergillus brasiliensis</em> using an LC-MS-based untargeted metabolomics approach, aiming to elucidate dynamic changes in metabolite profiles over 0, 3, 7, 10 and 15 days of cultivation. Key metabolites, such as gallic acid, epigallocatechin, mono- and di- <em>O</em>-galloylquinic acids, quercetin and citric acid, increased during cultivation, with a significant rise in gallic acid release and citric acid production observed after seven days. Fungal metabolites including hexylitaconic acid also increased, indicating potential to produce itaconic acid-derived compounds. Data analysis indicated that most significant metabolic changes occurred within the first seven days, especially for tannin hydrolysis and organic acid production. These findings highlighted the potential of <em>A. brasiliensis</em> to enhance fermented foods through targeted biotransformation.</p>
