“…Larvae of the black soldier fly (BSFL) can degrade a variety of organic substances, including livestock manure, agricultural waste, food waste, cyanobacteria, and pulp waste ( Gold et al, 2018 ; Niero et al, 2022 ; Peguero et al, 2022 ; Zhang et al, 2022 ; Lu, J. et al, 2022 ). BSFL can convert organic waste with low nutritional value into high-quality protein biomass ( Seyedalmoosavi et al, 2022 ).…”

Black soldier fly larvae (BSFL) can convert a variety of organic wastes into biomass, and its gut microbiota are involved in this process. However, the role of gut microbes in the nutrient metabolism of BSFL is unclear. In this study, germ-free BSFL (GF) and gnotobiotic BSFL (GB) were evaluated in a high-protein artificial diet model. We used 16S rDNA sequencing, ITS1 sequencing, and network analysis to study gut microbiota in BSFL that degrade proteins. The protein reduction rate of the GB BSFL group was significantly higher (increased by 73.44%) than that of the GF BSFL group. The activity of gut proteinases, such as trypsin and peptidase, in the GB group was significantly higher than the GF group. The abundances of different gut microbes, including Pseudomonas spp., Orbus spp. and Campylobacter spp., were strongly correlated with amino acid metabolic pathways. Dysgonomonas spp. were strongly correlated with protein digestion and absorption. Issatchenkia spp. had a strong correlation with pepsin activity. Campylobacter spp., Pediococcus spp. and Lactobacillus spp. were strongly correlated with trypsin activity. Lactobacillus spp. and Bacillus spp. were strongly correlated with peptidase activity. Gut microbes such as Issatchenkia spp. may promote the gut proteolytic enzyme activity of BSFL and improve the degradation rate of proteins. BSFL protein digestion and absorption involves gut microbiota that have a variety of functions. In BSFL the core gut microbiota help complete protein degradation. These results demonstrate that core gut microbes in BSFL are important in protein degradation.

“…The black soldier fly is a typical saprophagous insect originating from the Americas, and its larvae have been used in the bioremediation of organic waste [ 2 ]. Apart from food waste [ 3 ], black soldier fly larvae (BSFL) can also be used to treat various animal manures [ 4 ], cyanobacterial mud [ 5 ], and municipal sludge [ 6 ]. As a clean and environmentally friendly technology, BSFL can not only efficiently reduce the amount of organic waste but also provide high-quality insect protein with good economic benefits.…”

Black soldier fly is a saprophagous insect that has been widely reported in recent years due to its excellent performance in bioremediation. Due to the widespread presence of flocculants in the organic waste treated by black soldier fly larvae, this study aimed to evaluate the potential impacts and risks of flocculant addition (a combination of poly aluminum chloride and polyacrylamide with the ratio of 50:1). Results showed that the growth and weight of BSFL in the high-exposure groups (≥200 mg/L) were inhibited. The bioaccumulation of aluminum (Al) in larvae was estimated, and the proportions of different Al forms in the frass from high to low were the residual state (41.38 to 67.92%), water-soluble state (16.88 to 37.03%), acid-soluble state (8.45 to 18.72%), and alkali-soluble state (3.38 to 5.14%). The relative abundance of bacterial genera related to lipid metabolism decreased with increasing flocculant concentrations while disease-related taxa increased in relative abundance. The results serve as a reference for subsequent research and application of the treatment of flocculant-contaminated waste by BSFL.
