Mesophotic reefs are poorly known worldwide despite their great ecological relevance and management importance for coral reef conservation strategies. To aid in filling this gap, we conducted a pioneering, large-scale survey, covering total of around 315 miles length, the largest Brazilian coastal Marine Protected Area (MPA) Costa dos Corais. From digital bathymetry model (30 to 50 m depth) gen...

Complex microbiomes reside in marine sponges and consist of diverse microbial taxa, including functional guilds that may contribute to host metabolism and coastal marine nutrient cycles. Our understanding of these symbiotic systems is based primarily on static accounts of sponge microbiota, while their temporal dynamics across seasonal cycles remain largely unknown. Here, we investigated tempor...

Marine natural products (MNPs) have been an important and rich source for antimicrobial drug discovery effective alternative to control resistant infections. Herein, we report bioassay guided fractionation of marine extracts from sponges Lendenfeldia, Ircinia Dysidea that led us identify novel compounds with properties. Tertiary amines or quaternary amine salts: aniline 1, benzylamine 2, tertia...

Sponges, which constitute the phylum Porifera, are the most primitive of the multicellular animals, among all marine organisms screened. Marine sponges produce the largest number of structurally diversified natural products. In this study we investigated in vitro antimicrobial activity of Ircinia mutans collected from the Kish Island in the Persian Gulf against strains of bacteria Escherichia c...
