Summary: In this study, a non-denitrifying N2O-reducing bacterium, Flavobacterium azooxidireducens sp. nov., was discovered. This bacterium can consume significant amounts of N2O under anoxic conditions without releasing N2O. It serves as an electron sink for metabolism to sustain viability during transient anoxia and/or to detoxify high N2O concentrations.

Summary: Hermetia illucens larvae, also known as black soldier fly larvae (BSFL), are efficient in converting organic waste into high-quality biomass. This study explored the role of gut microbes in this process by culturing members of the core gut microbiota. Two cultivation strategies were employed, dilution-to-extinction cultivation and direct plating, resulting in the isolation of a diverse range of bacterial strains. Phylogenetic analysis identified predominant genera, such as Providencia, Proteus, Morganella, Enterococcus, Bacillus, and members of the family Enterobacteriaceae, which have been previously associated with the BSFL gut microbiota. Genomic fingerprinting provided insights into the genetic diversity of the cultured bacteria that could not be obtained solely through 16S rRNA gene sequencing.
