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 into high added-value products, and address environmental, societal and economic concerns. Due to its ability to feed on a tremendous variety of organic wastes, the black soldier fly (Hermetia illucens) has recently emerged as a promising insect for bioconversion of organic wastes on an industrial scale. A growing number of studies have highlighted the pivotal role of the gut microbiota in the performance and health of this insect species. This review aims to provide a critical overview of current knowledge regarding the functional diversity of the gut microbiota of H. illucens, highlighting its importance for bioconversion, food safety and the development of new biotechnological tools. After providing an overview of the different strategies that have been used to outline the microbial communities of H. illucens, we discuss the diversity of these gut microbes and the beneficial services they can provide to their insect host. Emphasis is placed on technical strategies and aspects of host biology that require special attention in the near future of research. We also argue that the singular digestive capabilities and complex gut microbiota of H. illucens make this insect species a valuable model for addressing fundamental questions regarding the interactions that insects have evolved with microorganisms. By proposing new avenues of research, this review aims to stimulate research on the microbiota of a promising insect to address the challenges of bioconversion, but also fundamental questions regarding bacterial symbiosis in insects.
利用昆虫进行生物转化是一种很有前景的策略，可将有机废物（餐饮剩饭、收获废弃物、食品加工副产品等）转化为可用于多种用途的生物质，转化为高附加值产品，并解决环境、社会和经济问题。由于黑水虻（Hermetia illucens）能够以种类繁多的有机废物为食，它最近已成为一种有前景的昆虫，可用于工业规模的有机废物生物转化。越来越多的研究强调了肠道微生物群在这种昆虫的性能和健康方面的关键作用。本综述旨在对当前关于黑水虻肠道微生物群功能多样性的知识进行批判性概述，强调其在生物转化、食品安全和新型生物技术工具开发方面的重要性。在概述了用于勾勒黑水虻微生物群落的不同策略之后，我们讨论了这些肠道微生物的多样性以及它们可为其昆虫宿主提供的有益服务。重点放在了技术策略以及宿主生物学中在不久的将来研究中需要特别关注的方面。我们还认为，黑水虻独特的消化能力和复杂的肠道微生物群使这种昆虫成为解决关于昆虫与微生物进化出的相互作用的基本问题的有价值模型。通过提出新的研究途径，本综述旨在激发对一种有前景的昆虫的微生物群的研究，以应对生物转化的挑战，以及关于昆虫中细菌共生的基本问题。
