“…Bacterial species at phylum level in five treatments are consistent with those reported in BSFL gut or residues bacterial (Li et al, 2022;Wu et al, 2023). However, the content at each phylum level differs greatly due to the substrate and the amount of waste consumed by BSFL.…”

“…At the genus level, the relative abundance of the top 30 genera of bacterial community differed significantly among different residues. Among them, Sphingobacterium and Dysgonomonas are the core microbes in the gut of BSFL, and they can significantly promote BSF development by increasing larval and pupal body weight gain (Li et al, 2022). In this study, their relative abundance of different treatment was consistent with BSFL bioconversion rate and body weight results, especially in the T1, which had 13.96% and 2.45 g (Figure . 5B, Figure .…”

Spent mushroom substrate (SMS) and wet distiller's grains (WDG) are growing organic wastes. The black soldier fly larvae (BSFL) can convert multiple organic wastes. However, there is limited information on their conversion by BSFL. Therefore, this study explores the conversion of SMS and WDG of five proportions by BSFL. This study shows that BSFL can convert SMS, WDG and their mixtures, 100% WDG is suitable for the growth of the BSFL. BSFL can promote the humification of the substrate during the treatment process, increasing the content of total kjeldahl nitrogen, total organic carbon, total phosphorus and total potassium in the residues. The fractionation mode of carbon and nitrogen elements and the microbial community in residue is obviously different, but that is closely relates to the physicochemical parameters and the microbial community of the substrate. The mixture treated by BSFL is helpful to form a residue with higher humus, but it may be unstable.

“…Recently, black soldier y larvae (Hermetia illucens L., BSFL) bioconversion technology has been widely recognized as a promising biotechnology for the treatment of domestic biodegradable waste (DBW), livestock manure, and sewage sludge (Qin et al 2022; ; ). This technology can not only convert organic waste into organic fertilizer (Xiang et al 2022), but also harvest larvae for animal feed and biofuel production (Parodi et al 2020). However, organic waste emits a large amount of greenhouse gases (CO 2 , CH 4 , and N 2 O) during the bioprocess, which is harmful to the environment (Akdeniz 2019).…”

Black soldier fly larvae (BSFL) have been proven to reduce greenhouse gas emissions in the treatment of organic waste (e.g., domestic biodegradable waste, DBW). However, the microbial mechanisms involved have not been fully understood. The current study mainly examined the dynamic changes of carbon and nitrogen, greenhouse gas emissions, the succession of microbial community structure, and changes in gene abundance in DBW under BSFL treatment (LT) and non-aeration composting (NC). We found that of the organic waste supplied, 29.9% carbon and 55.0% nitrogen were stored in BSFL. For every 1kg of dry matter of organic waste consumed, 655 g CO2, 0.80 mg CH4, and 2.26 mg N2O were emitted from LT, significantly lower than those from NC. 16S rRNA gene sequencing results showed that the BSFL increased the relative abundance of Methanophaga, Marinobacter, and Campylobacter during the bioprocess, enhancing the consumption of CH4 and N2O. The metagenomic data showed that the BSFL reduced the ratio of (nirK + nirS + nor)/nosZ in the residues, thereby reducing the emission of N2O. In addition, it increased the functional gene abundance of nirA, nirB, nirD, and nrfA, making nitrite more inclined to be reduced to ammonia. The BSFL mitigated greenhouse gas emissions by redistributing carbon and nitrogen and remodeling the community and function of microbiomes during the DBW bioconversion.
