Genome-wide transcriptional profiling of Bacillus subtilis in response to Hermetia illucens larvae extract

Project description:The black soldier fly, Hermetia illucens, is a promising source for sustainable production of proteins, lipids and bioactive substances. Feeding on a variety of decomposing organic substrates which are typically inhabited by a range of different microorganisms like bacteria and fungi, H. illucens larvae is expected to be able to strongly produce antimicrobial peptides (AMPs) and other substances possessing antibiotic activity. It has been shown that H. illucens larvae extract exhibits antimicrobial activity against some microorganisms, such as Escherichia coli and Staphylococcus aureus, and antimicrobial effect on bacterial biofilm. Numbers of AMPs produced by H. illucens larvae have also been identified so far. Moreover, H. illucens larvae extract was recently observed with significant induction of cell envelop stress response (CESR) in B. subtilis, indicative of potential production of antimicrobial compounds. B. subtilis as a well-established Gram‑positive model strain is widely used in scientific research and an arguably robust platform to investigate antimicrobial compounds at the respect of, such as the mode of reaction of and the stress response elicited by corresponding compounds. In this study, we aimed to characterize the stress responses in B. subtilis induced by H. illucens larvae extract by employing transcriptomic study via RNA sequencing technique. With transcriptional profiling, we are expecting to be able to give some hints of potential antimicrobial compounds produced by H. illucens larvae by referring to the transcriptomic researches on well-studied antimicrobial substances.

Proteomic insights into novel food insects: Homology-based proteome characterization and allergenicity considerations for EU-regulated insect species

Project description:Insects have emerged as a sustainable alternative protein source and recently gained regulatory approval in the European Union as novel foods and animal feed ingredients. However, the limited availability of species-specific proteomic databases presents a significant challenge for the accurate identification of proteins in insect-based food products, relevant for food authenticity, safety and allergenicity concerns. In this study, we developed a homology-based proteomic workflow to address the lack of comprehensive sequence data for edible insect species and to explore their allergenic potential. This nanoflow tandem mass spectrometry method (nano-HPLC HR-MS) aims to be generally applicable to underexplored species. We identified between 1079 and 1893 proteins for each of the six investigated insect species Acheta domesticus, Locusta migratoria, Tenebrio molitor, Alphitobius diaperinus, Gryllodes sigillatus and Hermetia illucens, increasing their numbers of known proteins up to 24-fold. Furthermore, we assessed the influence of error-tolerant peptide-spectra matching searches and database composition on protein identification and confirmed on average 90% of selected peptides using targeted methods. We consistently detected known and putative allergens across all tested species, providing further evidence on their allergenic potential. Data from this study may provide the general basis for the development of targeted parallel reaction monitoring mass spectrometry-based assays for so far unsequenced species authentication and quantification of their proteins e.g. in novel foods.
