Meeting the demands of growing population requires increased food and feed production, leading to higher levels agri-food waste. As this type waste seriously threatens public health environment, novel approaches management should be developed. Insects have been proposed as efficient agents for biorefining waste, producing biomass that can used commercial products. However, challenges in achieving optimal outcomes maximizing beneficial results remain. Microbial symbionts associated with insects are known a critical role development, fitness, versatility insects, such, they utilized targets optimization insect-based biorefinery systems. This review discusses biorefineries, focusing on agricultural applications edible mainly animal organic fertilizers. We also describe interplay between waste-utilizing microbiota microbial contribution enhancing insect growth, involvement bioconversion processes. The potential gut eliminating pathogens, toxins, pollutants microbe-mediated growth discussed. present outlines benefits using systems, describes roles insect-associated processes, highlights such systems addressing current waste-related challenges.

Introduction This study examines the optimum conversion of Wuzhishan pig manure by Black Soldier Fly Larvae (BSFL) at various phases development, as well impact gut microbiota on efficiency. Method and results In terms efficiency, BSFL outperformed growing stage (GP) group, with significantly higher survival rates (96.75%), fresh weight (0.23 g), larval rate (19.96%) compared to other groups. Notably, GP group showed significant dry matter reductions (43.27%) improved feed (2.17). Nutritional composition varied, having a lower organic carbon content. High throughput 16S rRNA sequencing revealed unique profiles, exhibiting an excess Lactobacillus Clostridium . Promising cellulose-degrading bacteria in intestines, including Bacillus cereus subtilis , superior cellulose degradation capabilities. The synergy these thermophilic greatly increased BSFL1-10 demonstrated high growth efficiency under specific conditions, remarkable moisture content (71.11%), residual (63.20%), waste reduction (42.28%). Discussion sheds light optimal stages for manure, dynamics, promising bacteria, enhancement through synergistic interactions. These findings hold great potential sustainable management efficient biomass conversion, contributing environmental preservation resource recovery.

Influence of agricultural waste‐based diets on growth performance, gut microbiome composition, and volatile organic compound profiles in Zophobas morio

Abstract With growing concerns over agricultural waste management and sustainable protein sources, insect farming has emerged as a promising valorization strategy. However, the effects of waste‐based diets on growth, gut microbiota, flavor quality edible insects remain unclear. This study investigates how different feeds influence biological characteristics Zophobas morio Fabricius (Coleoptera: Tenebrionidae), providing insights into its potential applications in recycling production. Over 32‐day feeding period, Z. were fed wheat bran (WB), mushroom sticks (EMS), or apple pomace (AP). Growth performance, volatile organic compounds (VOCs) analyzed using 16S rRNA sequencing gas chromatography‐ion mobility spectrometry (GC‐IMS). WB‐fed exhibited highest weight gain, with increased Lactobacillus Lactococcus , while EMS Spiroplasma without improving growth. AP maintained survival but reduced gain enriching Chryseobacterium Kosakonia . Gut microbiota influenced VOC profile, promoting formation esters ketones, enhancing sweet fruity volatiles, potentially reducing production alcohols sulfur‐containing compounds. These findings provide basis for optimizing solution an source.

Deciphering the functional diversity of the gut microbiota of the black soldier fly (Hermetia illucens): recent advances and future challenges

Animal Microbiome, Год журнала: 2023, Номер 5(1)

Опубликована: Авг. 31, 2023

Bioconversion using insects is a promising strategy to convert organic waste (catering leftovers, harvest waste, food processing byproducts, etc.) into biomass that can be used for multiple applications, turned high added-value products, and address environmental, societal economic concerns. Due its ability feed on tremendous variety of wastes, the black soldier fly (Hermetia illucens) has recently emerged as insect bioconversion wastes an industrial scale. A growing number studies have highlighted pivotal role gut microbiota in performance health this species. This review aims provide critical overview current knowledge regarding functional diversity H. illucens, highlighting importance bioconversion, safety development new biotechnological tools. After providing different strategies been outline microbial communities we discuss these microbes beneficial services they their host. Emphasis placed technical aspects host biology require special attention near future research. We also argue singular digestive capabilities complex illucens make species valuable model addressing fundamental questions interactions evolved with microorganisms. By proposing avenues research, stimulate research challenges but bacterial symbiosis insects.

The black soldier fly (Hermetia illucens) is attracting increasing interest for its ability to convert low-value substrates into highly nutritious feed. This study aimed at evaluating grape pomace from two varieties (Becuet - B; Moscato M) as rearing larvae (BSFL), focusing on the related effects larval growth performance, proximate composition, and fatty acid profile. A total of six replicates per treatment, 1 000 BSFL replica, were used. Larval development was assessed by weight, which recorded eight times during trial: day after beginning trial, then days 5, 8, 13, 15, 20, 22, 27 (day in 30% reached prepupal stage).

The interest in edible insects’ mass rearing has grown considerably recent years, thereby highlighting the challenges of domesticating new animal species. Insects are being considered for use management organic by-products from agro-industry, synthetic plastics industry including particular detoxification processes. processes depend on insect’s digestive system which is based two components: an enzymatic intrinsic cargo to insect species and another extrinsic provided by microbial community colonizing—associated with host. Advances have been made identification origin functions observed midgut. It now evident that microorganisms can adapt, improve, extend ability digest detoxify its food. Nevertheless, such as Hermetia illucens Tenebrio molitor surprisingly autonomous, no obligatory symbiosis a microorganism yet uncovered digestion. Conversely, intestinal microbiota given take different forms, largely influenced host’s environment diet. This flexibility offers potential development novel associations between insects microorganisms, could result creation synergies would optimize or expand value chains agro-industrial by-products, well contaminants.
