Chlorinated metabolites with antibacterial activities from a deep-sea-derived fungus.

Chromatographic separation of the solid cultures of a deep-sea-derived fungus (MCCC 3A00308) resulted in the isolation of eight compounds. Their structures were identified on the basis of the spectroscopic data. Compounds 1-8 are classified as depsidone-type (1-4), isocoumarin-type (5 and 6), and benzothiazole-type (7 and 8), of which 1-7 are new compounds and 1-3 along with 5 and 6 are chlorinat...

Delivery mode and perinatal antibiotics influence the predicted metabolic pathways of the gut microbiome.

Delivery mode and perinatal antibiotics influence gut microbiome composition in children. Most microbiome studies have used the sequencing of the bacterial 16S marker gene but have not reported the metabolic function of the gut microbiome, which may mediate biological effects on the host. Here, we used the PICRUSt2 bioinformatics tool to predict the functional profiles of the gut microbiome based ...
