Characterisation of key components of biofertiliser produced from mackerel wastewater and commercialisation feasibility analysis of the biofertiliser production process for wastewater valorisation

Microbial production of biofertiliser attracts much attention due to complete reuse of fish wastewater and enhanced yields in agriculture. Herein, key components of biofertiliser (cells and hydrolysates) were characterised to determine the quality of biofertiliser from mackerel wastewater (MWW). Thr...

description Microbial production of biofertiliser attracts much attention due to complete reuse of fish wastewater and enhanced yields in agriculture. Herein, key components of biofertiliser (cells and hydrolysates) were characterised to determine the quality of biofertiliser from mackerel wastewater (MWW). Through fed-batch biodegradation, a high number (5.33 × 109 CFU/mL) of viable cells and rich low-molecular-weight hydrolysates were obtained with a high degree of hydrolysis (48.1%). Cells exhibited plant growth-promoting activities, while hydrolysates (

Cells exhibited plant growth-promoting activities, while hydrolysates (&lt;2 kDa) exhibited high antioxidant activities of 84.17% for 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 98.45 for 2,2′-azino-bis(ethybenzthiazoline-6-sulfonic acid) (ABTS).
