Dynamic changes in molecular composition of black soldier fly prepupae and derived biomasses with microbial fermentation

A metanalysis to evaluate the effects of substrate sources on the nutritional performance of black soldier fly larvae: implications for sustainable poultry feed

“…The LL was higher in larvae fed Fermentation Residues than those fed on other substrates, implying the potential of Fermentation Residues to promote larval elongation. Similarly, higher prepupal lengths were noted in larvae fed on Feed Waste and Food Waste substrates, further affirming the correlation between substrate type and larval growth metrics ( Meneguz et al, 2018 ; Grossule and Lavagnolo, 2020 ; Luparelli et al, 2022 ). The SRR was higher in larvae fed Fruits and MIXX substrates.…”

“…Lastly, the fruits diet resulted in a higher chitin content compared to the Food Waste and Feed Waste diets. This finding could be related to the specific nutritional composition of fruits that possibly stimulates chitin production in BSF larvae ( Luparelli et al, 2022 ). These results highlight the importance of substrate selection in BSF rearing, which directly impacts the nutritional profile of the resulting larvae meal.…”

“…These substrates possibly present a more balanced composition of macro and micronutrients, as well as a diverse array of bioavailable compounds that can cater to the broad nutritional requirements of the growing larvae ( Lopes et al, 2022 ). BSF larvae are recognized for their omnivorous feeding habits, thus, a diversified substrate ( Singh et al, 2021 ; Villa et al, 2021 ; Luparelli et al, 2022 ), offering a broad spectrum of nutrients, may be beneficial for their growth and survival. It also signifies the role of substrate quality and nutrient profile in influencing the survival rate ( Rehman et al, 2017 ; Meneguz et al, 2018 ; Lopes et al, 2020 ), demonstrating the need for careful substrate selection based on the intended outcomes of the BSF rearing process.…”

“…The larvae of this fly exhibit remarkable voracity for organic matter and have the ability to bioconvert waste materials into nutrient-rich biomass suitable for use as poultry feed ( Meneguz et al, 2018 ; Kim et al, 2020a ; Yang et al, 2022 ; Facey et al, 2023 ). The nutritional composition of BSF larvae is highly dependent on the substrate used for their rearing, a factor that is thus crucial for the quality and suitability of the resulting BSF larva meal for specific applications ( Grossule and Lavagnolo, 2020 ; Hopkins et al, 2021 ; Luparelli et al, 2022 ). Although BSF larvae are known to have a broad dietary range, the precise effects of substrate composition on larval growth, nutrient composition, and bioconversion efficiency remain not completely understood.…”

Insights into the Gut Microbial Communities of Broiler Chicken Fed Black Soldier Fly Larvae-Desmodium-Based Meal as a Dietary Protein Source

“…As suggested in other studies [ 32 ], chitin is a naturally occurring polysaccharide that can be fermented by microbes, degraded by SCFA-producing bacteria, and may also serve as a substrate for microbes. The lactic acid produced by LABs could facilitate fermentation that produces hydrolytic enzyme that acts on proteins and polysaccharides such as chitin [ 33 ]. Studies have reported that high bacterial diversity is regarded to be beneficial to gut health because rich communities are likely to compete with pathogens for resources and colonization, preventing pathogen invasion and infection [ 34 ].…”
