Separate Hydrolysis and Fermentation of Kitchen Waste Residues Using Multi-Enzyme Preparation from Aspergillus niger P-19 for the Production of Biofertilizer Formulations

This study addresses the management of kitchen waste by transforming it into biofertilizer formulations, utilizing an effective, in-house-developed multi-enzyme preparation. An approach consisting separate hydrolysis and fermentation bioprocessing processes was used, employing a preparation from Aspergillus niger P-19 to separately hydrolyze waste, followed hydrolysate for growth Klebsiella pneumoniae AP-407, which has traits. led simultaneous generation liquid as well carrier-based formulations with viable cell counts 3.00 × 1012 CFU/mL CFU/g, respectively. Both significantly enhanced morphometric characteristics leaf chlorophyll contents Tagetes erecta, in addition enriching soil essential nutrients. The current adopted novel processing technology manufacturing both carrier biofertilizers, adopting zero-waste waste.
