Clostridium perfringens suppressing activity in black soldier fly protein preparations

Abstract Clostridium perfringens is a commensal, but also an opportunistic pathogen that can lead to lethal diseases as a result of overgrowth when homeostasis is disrupted. The current course of treatment is antibiotics. However, with increasing antibiotic resistance alternatives are required. We investigated the antimicrobial capacity of digest from different black soldier fly- and mealworm-derived fractions towards C. perfringens by using in vitro models. Culturing C. perfringens with digest of insect-derived fractions showed that fractions containing black soldier fly larvae protein significantly (p
