Taxonomic studies were performed on 13 clinical isolates (ten of which were epidemiologically related) that had been previously identified as Oerskovia turbata. Comparative phylogenetic analysis, based on 16S rRNA gene sequences, indicated that the isolates are closely related to Cellulosimicrobium cellulans with sequence similarity values ranging from 99.5 to 99.8 %. Chemotaxonomic results (fatty acid profiles and menaquinones) supported the inclusion of these isolates in the genus Cellulosimicrobium. The DNA G+C content was 74.5 mol%. The results of DNA-DNA reassociation, whole-cell sugars (with galactose as the characteristic whole sugar) and phenotypic properties, including antimicrobial resistance, indicated that these isolates are representatives of a novel species of the genus Cellulosimicrobium. The name Cellulosimicrobium funkei sp. nov. is proposed for the novel strains, with strain W6122T (=ATCC BAA-886T = DSM 16025T = CCUG 50705T) as the type strain. The definition of this novel Cellulosimicrobium species will assist in the understanding of the epidemiology and clinical significance of these micro-organisms.

Inflammatory Bowel Disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract characterized by disrupted immune function. Indeed, gut microbiota dysbiosis and metabolomic profile alterations, are hallmarks of IBD. In this scenario, metabolite-sensing G-protein coupled receptors (GPCRs), involved in several biological processes, have emerged as pivotal players in the pathophysiology of IBD.

Representatives of the genus Acanthamoeba are among the most widespread protists in the environment. They have a ubiquitous distribution and can sometimes cause quite serious pathologies in humans. The treatment ofp rotozoal infections caused by free-living amoebae is currently limited and often unsuccessful.

Bioprospecting the secondary metabolism of underexplored Actinomycetota taxa is a prolific route to uncover novel chemistry. In this work, we report the isolation, structure elucidation, and bioactivity screening of cellulamides A and B ( and ), two novel linear peptides obtained from the culture of the macroalga-associated CT-R177. The host of this microorganism, the Chlorophyta , was collected in the northern Portuguese coast and, in the scope of a bioprospecting study focused on its associated actinobacterial community, strain CT-R177 was isolated, taxonomically identified, and screened for the production of antimicrobial and anticancer compounds.

The insect larvae Protaetia brevitarsis seulensis have recently been researched as a nutritious food source and concentrated on their environmental impacts. Therefore, their gut microbiota has been studied to elucidate their effects and roles on the environment. Of the abundance of bacterial genus identified based on the 16S rRNA genes from isolates of the gut of insect larva Protaetia brevitarsis seulensis, six of the prominent genus were identified as Bacillus (40.
