Enhanced Fermentation for Lactic Acid Production from Food Waste via Hydrothermal Pretreatment: Performance Evaluation and Metagenomic Analysis

This dataset contains metagenomic sequencing data associated with the study titled "Enhanced Fermentation for Lactic Acid Production from Food Waste via Hydrothermal Pretreatment: Performance Evaluation and Metagenomic Analysis." The research evaluates how hydrothermal pretreatment at temperatures ranging from 80 to 140 degrees C, followed by centrifugal supernatant recovery, improves substrate hydrolysis and mixed-culture lactic acid fermentation efficiency from food waste (FW) at low pH. Metagenomic sequencing was conducted to analyze microbial community changes, highlighting the enrichment of Lactobacillus amylolyticus and Lactobacillus delbrueckii, and identifying key functional genes related to lactic acid production. Results demonstrate enhanced fermentation performance, increased lactic acid yields, and reduced formation of fermentation byproducts.
