In this study, we investigated the taxonomic identity and biotechnological potential of the actinobacterium Streptomyces sp. LaBMicrA B280, isolated from the rhizosphere of Inga edulis (Mart.). Our approach combined a phylogenomic approach, annotation of metabolic subsystems and biosynthetic gene clus...
Lactic acid bacteria (LAB) play an essential role in mammalian gut health and are promising candidates for probiotic use. In this study, we have identified LAB isolated from fecal samples of bats, calves, cats, or piglets or from the vaginal mucosa or teat skin of a ...
Despite the increasing use of plant-based energy ingredients in aquaculture, few studies have evaluated the digestibility of practical diets formulated with these ingredients in an integrated manner with the metabolic responses, intestinal health, and productive performance of fish. This limits t...
The genus Streptomyces is recognized as a source of secondary metabolites (SMs) with applications in medicine, industry, and agriculture. This study presents the description and characterization of a new Streptomyces species, isolated from sediments of the Madeira River in the Brazilian Amaz...
