- Abstract
To explore the comprehensive utilization of agricultural wastes, solid-state fermentation was applied to residues of Flammulina velutipes (F. velutipes) and vinegar for use in culturing earthworms. Fermentation technology and earthworm culture technology were optimized by response surface methodology in this study. The optimal fermentation product for earthworm culture was obtained under an inoculum amount of 7.5%, fermentation temperature of 25.6 °C, pH 7.7 and protein content of 18.23%. The optimum culture conditions were a culture density of 18.4 individuals/dm3, an initial pH of 7.2 and a fermentation temperature of 26.8 °C. The daily weight gain multiplier of earthworms was 0.0387 units, and it increased significantly compared with that of the unfermented and cow dung groups. The fermented product of F. velutipes and vinegar residues could be used to culture earthworms and improve the metabolism and antioxidant capacities of earthworms. This provides a new way to comprehensively utilize agricultural waste resources.
