Optimizing food waste biodigestion: pre-selection of microbial groups and isolated enzymes using the plackett-burman experimental design

This study investigated the use of anaerobic biodigestion as an ecological technique for treating organic waste in urban solid waste. Biogas production is carried out through action microorganisms, and enzymatic hydrolysis can increase biogas production, although it presents economic challenges. The aim was to pre-select microbiological groups enzymes optimize process using statistical tools. Organic from a restaurant sludge sewage treatment plant Brazil were used, three bacterial strains 12 well commercial enzymes, evaluated. divided into four stages reduce number independent variables accuracy methane results. results indicated that careful selection microbial had significant positive impact on production. interaction between pre-selected microorganisms resulted effects cumulative biometane concluded essential maximize efficiency digestion process. Further, more detailed identification their interactions needed further In general, appropriate choice fundamental success
