Freshwater Sponge Tubella variabilis Presents Richer Microbiota Than Marine Sponge Species

open access: yesFrontiers in Microbiology, 2019
Sponges can host diverse and abundant communities of microorganisms, which constitute an interesting source of bioactive compounds. Thus, to broaden our knowledge about the diversity of the microbiota that is found in freshwater sponges, the microbial ...

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont

open access: yesAngewandte Chemie, EarlyView.
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

Cell cycle analysis of primary sponge cell cultures [PDF]

open access: yes, 2011
Proliferation of sponge cells is generally measured via cell counts or viability assays. However, more insight into the proliferative state of a sponge cell population can be obtained from the distribution of the cells over the different phases of the ...

Broad‐Spectrum, Cell Envelope‐Active Marinocyclin Antibiotics From a Coral‐Derived Bacterium Are Effective Against Colistin‐Resistant Bacteria

open access: yesAngewandte Chemie, EarlyView.
Marinocyclins, polycationic macrocyclic depsipeptides, were discovered by genome mining from the marine coral‐derived bacterium Aquimarina megaterium. The compounds have broad‐spectrum activity against gram‐positive and gram‐negative ESKAPE bacteria.

Studies of chemical distribution and pharmacological activities of porifera-derived alkaloids: A review (2000–2023)

open access: yesEuropean Journal of Medicinal Chemistry Reports
This review explores the non-random distribution of chemical novelty among marine invertebrate phyla, with a particular focus on Porifera (sponges), which have exhibited the highest average count of novel natural products per species since 1990. Sponges,

Characterization of Bacterial, Archaeal and Eukaryote Symbionts from Antarctic Sponges Reveals a High Diversity at a Three-Domain Level and a Particular Signature for This Ecosystem.

open access: yesPLoS ONE, 2015
Sponge-associated microbial communities include members from the three domains of life. In the case of bacteria, they are diverse, host specific and different from the surrounding seawater.
