Abstract Marine Porifera host diverse microbial communities, which influence metabolism and fitness. However, functional relationships between sponge microbiomes metabolic signatures are poorly understood. We integrate microbiome characterization, metabolomics predicted functions of four coexisting Mediterranean sponges – Petrosia ficiformis , Chondrosia reniformis Crambe crambe Chondrilla nucula . Microscopy observations reveal anatomical differences in densities. Microbiomes exhibit strong...
Abstract Marine sponges are widespread, sessile, filter-feeding animals, known for living in association with complex prokaryotic communities structured by host species. Though marine fungi ubiquitous across environments, little is about sponge-associated fungal (mycobiome). Indeed, aside from a few studies based on the isolation of strains biotechnological purposes, information available to understand diversity and structure sponge mycobiome. Here, metabarcoding approach ITS1 marker was...
Ocean Acidification (OA) profoundly impacts marine biochemistry, resulting in a net loss of biodiversity. Porifera are often forecasted as winner taxa, yet the strategies to cope with OA can vary and may generate diverse fitness status. In this study, microbial shifts based on V
Communication among marine organisms are generally based on production, transmission, and interpretation of chemical cues. Volatile organic compounds (VOCs) can act as infochemicals, ocean acidification alter their production in the source well information they drive to target organisms. Two diatoms ( Cocconeis scutellum var. parva Diploneis sp.) a macroalga Ulva prolifera ), all common epiphytes Posidonia oceanica leaves, were isolated cultured at two pH conditions (8.2 7.7). Their biomass...
Ocean acidification (OA) is a dramatic perturbation of seawater environments due to increasing anthropogenic emissions CO2. Several studies indicated that OA frequently induces marine biota stress and reduction biodiversity. Here, we adopted the macroalga Ulva prolifera as model applied complementary multi-omics approach investigate metabolic profiles under normal acidified conditions. Our results show U. grows at higher rates in environments. Consistently, observed lower sucrose...
The continuous outbreak of drug-resistant bacterial and viral infections imposes the need to search for new drug candidates. Natural products from marine bacteria still inspire design pharmaceuticals. Indeed, have unique metabolic flexibility inhabit each ecological niche, thus expanding their biosynthetic ability assemble unprecedented molecules. One-Strain-Many-Compounds approach tandem mass spectrometry allowed discovery a Shewanella aquimarina strain as source novel imidazolium alkaloids...
The Gram-negative Pantoea eucrina D2 was isolated from the marine sponge Chondrosia reniformis. Sponges were collected in a shallow volcanic vents system Ischia island (South Italy), influenced by CO2 emissions and lowered pH. chemical diversity of secondary metabolites produced this strain, under different culture conditions, explored combined approach including molecular networking, pure compound isolation NMR spectroscopy. metabolome cf. yielded very complex network, allowing annotation...
Marine invertebrates are a traditional source of natural products with relevant biological properties. Tunicates soft-bodied, solitary or colonial, sessile organisms that provide compounds unique in their structure and activity. The aim this work was to investigate the chemical composition ascidian
Ocean acidification (O.A.) influences the ecology of oceans and it may impact plant-animal interactions at various levels. Seagrass meadows located acidified vents in Bay Naples (Italy) are considered an open window to forecast effects global-changes on aquatic communities. Epiphytic diatoms genus Cocconeis abundant seagrass meadows, including environments, where they play key ecological roles. A still-unknown apoptogenic compound produced by triggers suicide androgenic gland Hippolyte...
Modern research makes frequent use of animal models, that is, organisms raised and bred experimentally in order to help the understanding biological chemical processes affecting or whole environments. The development flexible, reprogrammable modular systems may automatic production 'not-easy-to-keep' species is important for scientific purposes such aquaculture needs as alive foods, culture small larvae test new procedures. For this reason, we planned built a programmable experimental system...
Cyanobacteria may live in the water column and benthos of aquatic environments, or be symbionts other organisms, as case Phormidium-like cyanobacteria, known to influence ecology freshwater marine ecosystems. A strain cyanobacteria has been recently isolated a free-living epiphyte leaves Posidonia oceanica (L.) Delile Mediterranean sea its biology are herein investigated. It was identified Halomicronema metazoicum, previously uniquely symbiont sponges. We cultivated it range light...
During scientific expeditions in Indonesia and Vietnam, several sponge specimens belonging to the genus Cladocroce were collected. The integration of morphological molecular analyses, incorporating species delimitation models (ABGD, ASAP, bPTP) phylogenetic approaches using three markers (COI, 28S, 18S–ITS1–5.8S–ITS2–28S), allowed us discriminate congeneric species. Two these (C. burapha C. pansinii sp. nov.) supported by data, whereas a third lamellata was delimited data only. We formally...
The marine environment is potentially a prolific source of small molecules with significant biological activities. In recent years, the development new chromatographic phases and progress in cell molecular techniques have facilitated search for natural products (MNPs) as novel pharmacophores enhanced success rate selection potential drug candidates. However, most this exploration has so far been driven by anticancer research limited to reduced number taxonomic groups. article, we report test...
Abstract Phormidium ‐like cyanobacteria produce a variety of biologically active molecules. We isolated free‐living strain Halomicronema metazoicum , previously known uniquely as symbiont marine sponges, and demonstrated that its spent medium was toxic for various protozoans fish parasites. However, we still ignore if mats contain constitutive or activated defences influencing the physiology other organisms, with potential influences on organisms share same environment. The goal this study...
