OPTIMIZATION OF ANAEROBIC DIGESTION FOR PRODUCTION OF BIOFERTILIZER-BIOFUNGICIDE TO BIOCONTROL Mycosphaerella fijiensis

The aim of this research was to optimize the production a novel organic biofertilizer with fungicidal effect in a continuous anaerobic bioreactor optimizing the main operational parameters that control the anaerobic digestion process. A 2 4 factorial, central composite design (CCD) was...
