Project description:Fresh fish are highly perishable food products and their short shelf-life limits their commercial exploitation, leads to waste and has a negative impact on aquaculture sustainability. New non-thermal food processing methods, such as High pressure (HP), are being investigated to prolong shelf-life while assuring high food quality. We applied several tools to evaluate the impacts of HP processing on European sea bass (Dicentrarchus labrax) fillets quality and shelf life. The data here presented includes visual and physical measurements of flesh quality and the microbiome and proteome profiles of control and HP-processed sea bass fillets (600MPa, 25ºC, 5min), after isothermal storage (2°C) for different periods ranging from 1 to 67 days. Color (L-, a- and b- values) change and texture (hardness, cohesiveness and adhesiveness) parameters were obtained by using appropriate colorimeter and texture analyser, respectively, during refrigerated storage. Bacterial diversity was analysed by Illumina high-throughput sequencing of the 16S rRNA gene in five pooled DNAs from control or HP-processed fillets after 1, 11 or 67 days and the raw reads were deposited in the NCBI-SRA database with accession number PRJNA517618. In addition, high-throughput sequencing of the internal transcribed spacer (ITS) region targeting yeast and moulds was run for control or HP-processed fillets at the end of storage (11 or 67 days, respectively), being deposited under SRA accession PRJNA517779. Quantitative label-free proteomics profiles were analysed by SWATH-MS (Sequential Windowed data independent Acquisition of the Total High-resolution-Mass Spectra) in myofibrillar or sarcoplasmic enriched protein extracts pooled for control or HP-processed filets after short (1d) or long-term (11-67 days) storage. These data support the findings reported in “High pressure processing of European sea bass (Dicentrarchus labrax) fillets and tools for flesh quality and shelf life monitoring” (Tsironi et al. 2019).

Project description:We aimed at obtaining a reference transcriptome for the European seabass. We characterized by Illumina paired-ends RNA-seq the D. labrax transcriptome for two targeted organs, using a diversity of conditions, animal stages and genotypes to warranty the widest variety of reconstructed transcripts. The brain (including pineal gland and pituitary) and liver were chosen as they are complementary and at a crossroads of many key neuroendocrine, metabolic and behavioral regulations. Dicentrarchus labrax_2 targeted organs (liver and brain) with two technical replicates each (using two different fragment sizes) half a GAIIX run total. We used two flow cells per organ and each was corresponding to a different fragment size. The expected sizes were 350 and 500bp.

Project description:The aim of the project was to identify differently expressed genes in eggs of European seabass (Dicentrarchus labrax) characterized by different quality. In this way it was expected to identify genes possibly being a molecular indicator of egg quality in this species, which was never studied to date. For the study microarray analysis of over 26 thousand genes in 16 egg batches was performed. Additionally, for each egg batch biological quality was determined, what allowed to compare the gene expression profile with overall egg quality (divided into two groups representing ‘high’ and ‘low’ egg quality). The analysis allowed to identify 39 differently expressed genes between the two groups representing ‘high’ and ‘low’ egg quality. From those genes, expression level of 7 were verified by real-time qPCR which confirmed significant difference in expression in 5 of them.

Project description:The impact of mono-chronic S. stercoralis infection on the gut microbiome and microbial activities in infected participants was explored. The 16S rRNA gene sequencing of a longitudinal study with 2 sets of human fecal was investigated. Set A, 42 samples were matched, and divided equally into positive (Pos) and negative (Neg) for S. stercoralis diagnoses. Set B, 20 samples of the same participant in before (Ss+PreT) and after (Ss+PostT) treatment was subjected for 16S rRNA sequences and LC-MS/MS to explore the effect of anti-helminthic treatment on microbiome proteomes.

Project description:<p>Dietary glycerol supplementation in aquaculture feed is seen as an alternative and inexpensive way to fuel fish metabolism, attenuate metabolic utilization of dietary proteins and, subsequently reduce nitrogen excretion. In this study, we evaluated the impact of dietary glycerol supplementation has on nitrogen excretion of European seabass (Dicentrarchus labrax) and its effects on metabolite profile and bacterial community composition of gut digesta. These effects were evaluated in a 60-day trial with fish fed diets supplemented with 0, 2.5 or 5% (w/w) refined glycerol. Nuclear magnetic resonance spectroscopy and high-throughput 16S rRNA sequencing characterized the effects of glycerol supplementation of digesta metabolite and bacterial community composition of 6h postprandial fish. Our results showed ammonia excretion was not altered by dietary glycerol supplementation and the highest glycerol dosage was associated with significant increases in amino acids and a significant decrease of ergogenic creatine in digesta metabolome. Concomitantly, significant decreases in putative amino acid degradation pathways were detected in the predicted metagenome analysis, suggesting a metabolic shift. Taxon-specific analysis revealed significant increases in abundance of some specific genera (e.g. Burkholderia and Vibrio) and bacterial diversity. Overall, our results indicate glycerol supplementation may decrease amino acid catabolism without adversely affecting fish gut bacterial communities.</p>
