Host-microbe interactions play crucial roles in marine ecosystems. However, we still have very little understanding of the mechanisms that govern these relationships, evolutionary processes shape them, and their ecological consequences. The holobiont concept is a renewed paradigm biology can help to describe understand complex systems. It posits host its associated microbiota with which it interacts, form holobiont, be studied together as coherent biological functional unit biology, ecology,...
Abstract Bacterial communities play an essential role for the function of marine macroalgae. Recent work has shown that bacterial associated with individual macroalgae possess on a local scale functional core is likely derived from diverse members guilds. It not known whether such cores also exist across large spatial scales or between closely related host species. To address this, we studied here three species green macroalgal genus Ulva different geographic locations. While taxonomic...
ABSTRACT Two constructs derived from the α-amylase gene ( amyA ) of Lactobacillus amylovorus were expressed in plantarum , and their expression products purified, characterized, compared. These correspond to complete (AmyA) truncated (AmyAΔ) forms α-amylase; AmyAΔ lacks 66-kDa carboxyl-terminal direct-repeating-unit region. AmyA exhibit similar amylase activities towards a range soluble substrates (amylose, amylopectin α-cyclodextrin, starch). The specific enzymes starch are similar, but K M...
The renal catabolism of [ 125 I]glucagon-like peptide 1 (GLP-1) and 2 (GLP-2) has been studied both in vivo, by the disappearance these peptides from plasma bilaterally nephrectomized (BNX), ureteral-ligated (BUL) or normal rats, vitro, analyzing their isolated, perfused rat kidney. Results vivo studies demonstrated that half-disappearance time for was lower controls than BUL this value rats not significantly different BNX rats. In addition, metabolic clearance rate GLP-1 higher control...
Abstract Incorporating macroalgae like Ulva species into integrated multi-trophic aquaculture (IMTA) enhances sustainability by filtering effluents and provide epiphytic bacteria, that can contribute to disease prevention. Colonizing ohnoi with Phaeobacter sp. 4UAC3 is promising for control in IMTA systems, but high light intensity impacts ’s persistence on . This study investigated the effect of different intensities regimes ability 4UAC3·to colonize U. Experiments assessed algal growth,...
Marine research impact should be translated into economic, environmental, social and cultural benefits to lead progress transformation towards more sustainable scenarios resilient coastal territories. For this take place: 1) scientific knowledge reach public private agents sectors, as well the society a whole, 2) recipients permeable knowledge. Facilitating proper flow would give it greater transformative potential, advancing in marine sustainaility.In frame of Complementary Plan for...
Abstract The green alga Ulva ohnoi M. Hiraoka & S. Shimada is an effective biofiltration agent of fish effluents in Integrated Multi-Trophic Aquaculture Recirculation Systems (IMTA-RAS), due to its high growth rate and nutrient (N P) removal temperate conditions. Moreover, species provide important niche for biofilm-forming bacteria, including strains Phaeobacter that possess antagonistic activity against pathogenic Vibrio species, have been shown reduce the mortality aquaculture...
A Gram-positive-staining, motile, rod-shaped, endospore-forming bacterium (BFLP-1( T)) was isolated from faeces of wild long-snouted seahorses ( Hippocampus guttulatus) captured in north-west Spain (Toralla, Galicia). Strain BFLP-1(T) grew at 10-30 degrees C and pH 5.5-9 (optimally 20 7.2) with 0-7 % (w/v) NaCl 2 NaCl). The G+C content the DNA 48.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain a member genus Bacillus most closely related to herbersteinensis...
To develop a SYBR Green quantitative real-time PCR protocol enabling detection and quantification of fish probiotic two turbot pathogenic Vibrio spp. in microcosms.Phaeobacter 27-4, anguillarum 90-11-287 splendidus DMC-1 were quantified as pure mixed cultures presence microalgae (Isochrysis galbana), rotifers (Brachionus plicatilis), Artemia nauplii or (Psetta maxima) larvae by based on primers directed at genetic loci coding for antagonistic virulence-related functions respectively. The...
Breeding in captivity for research or exhibition (e.g. aquaria) can replace the capture of wild specimens endangered species and allow controlled reinforcement populations. With this aim, diet analysis establishing adequate prey are determinant factors breeding success. However, non-invasive approaches such as faecal DNA advisable analysing these species. Therefore, aim present study was to demonstrate usefulness by specific PCR amplification assessing seahorse Hippocampus guttulatus. In a...
A Gram-negative, facultatively anaerobic, motile and slightly curved rod-shaped bacterium (BFLP-4T) was isolated from the faeces of wild seahorses (Hippocampus guttulatus) captured in northwest Spain (Toralla, Galicia). Strain BFLP-4T grew at 10–35 °C pH 5–9 (optimally 20 7.2) salt concentrations range 0–7% w/v NaCl. The G+C content DNA 49.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain a member genus Vibrio, being most closely related to Vibrio ichthyoenteri...
