“…This is likely a key reason why BSFL bioconversion technology reduced greenhouse gas emissions in organic waste treatment. On the other hand, BSFL bioconversion technology had the advantage of short cycles (Singh et al 2023). In this experiment, the degradation e ciency of carbon and nitrogen in NC was 0.48% per day and 0.90% per day, while these were found as was 5.14% per day and 4.78% per day in LT, indicating a signi cantly higher degradation e ciency with BSFL bioconversion technology.…”

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.

“…According to Cottrell et al [7], insect protein stands out as the most promising alternative to fishmeal when compared to other emerging protein sources like micro-and macroalgae, bacteria, and yeast. Indeed, insect meal (IM), predominantly derived from Hermetia illucens (HI) and Tenebrio molitor (TM) larvae, has demonstrated an enormous potential as an alternative protein source to partially and totally replace FM in diets for both freshwater and marine fish species, including European seabass (Dicentrarchus labrax), a key fish species in Mediterranean aquaculture [8]. Despite this, the majority of studies have primarily focused on fish growth, nutrient digestibility, intestinal health, and the final quality of fish intended for human consumption, overlooking the effect of the dietary inclusion of IM on fish response to stress, which in the long term may result in adverse effects on animal health and overall performance [9].…”

This study aimed to explore the effect of FM substitution by defatted Tenebrio molitor larvae meal (dTM) on the response of European seabass to an acute stress challenge. An FM-based diet was used as a control and two other isoproteic/isoenergetic diets were formulated to replace 50 and 100% of FM by dTM. Each diet was tested in quadruplicate groups of 15 fish (69 ± 5 g) fed until visual satiety for 16 weeks. After the feeding trial, fish were subjected to 1 min air exposure followed by 1 h of recovery before sampling. The haematological profile, plasma metabolites, and humoral immunity biomarkers, as well as hepatic oxidative stress and antioxidant capacity, were analysed. A clear response to acute stress was observed by a significant increase in haemoglobin, haematocrit, red blood cells, and almost all evaluated plasma metabolites and humoral parameters, regardless of dietary treatment. The obtained results demonstrated that partial substitution of FM by IM did not affect the stress response of seabass. However, total FM replacement increased the hepatic activity of total peroxidase and superoxide dismutase in fish fed TM100.
