Simultaneous extraction of calcium phosphates and proteins from fish bones. Innovative valorisation of food by-products.

ABSTRACT: By products of the fish industry can be a source of valuable molecules, with different technological applications. Fish bones, in particular, contain both organic and inorganic phases (collagen, other proteins and calcium phosphate respectively), with uses in cosmetics and biomedicine. Using the most common extraction protocols, only of the two phases can be extracted, while the other one is degraded. Investigation of the organic phase composition by proteomic related procedures followed by LC MS MS analysis, showed that the main extracted proteins were collagen in its different forms (especially alpha 1); some differences were observed between salmon and sea bream and between the methods of extraction. Biocompatibility tests performed on both organic and inorganic extracts (with fibroblast and osteoblast like cellular lines) showed their non toxicity and, hence, their suitability for cosmetic or biomedical applications.

Organic Nitrogen Source is Critical for Welan Production in Sphingomonas sp. ATCC 31555

Project description:Welan gum is mainly produced by Sphingomonas sp. ATCC 31555 and has broad applications in industry such as that in cement production. Both carbon and nitrogen sources are essential for welan production. However, how nitrogen sources affect the metabolism and gene transcription of welan remains elusive. Here, we used next-generation sequencing RNA-seq to analyze the transcriptome of Sphingomonas sp. ATCC 31555 in the presence of inorganic or organic nitrogen sources. Enriched gene expression and pathway analysis suggest that organic nitrogen sources significantly enhanced the expression of genes in central metabolic pathways of Sphingomonas sp. ATCC 31555 and those critical for welan synthesis compared to that observed using inorganic nitrogen sources. The present study improves our understanding of the molecular mechanism underlying the use of nitrogen in welan synthesis in Sphingomonas sp., as well as provides an important transcriptome resource for Sphingomonas sp. in relation to nitrogen sources. Sphingomonas sp. ATCC 31555 strain (stored in our laboratory) was first seeded in an inoculum medium (20 g/L glucose, 3 g/L yeast extract, 3 g/L malt extract, and 5 g/L fish meal protein peptone, pH 7.0), and then cultured in a fermentation medium containing 40 g/L sucrose, 4.0 g/L nitrogen source, 0.6 g/L KH2PO4, and 0.2 g/L MgSO4.7H2O at 37Â°C. The nitrogen sources used in the present study were as follows: NaNO3 (4.0 g/L) as inorganic nitrogen (IN), beef extract (4.0 g/L) as organic nitrogen (ON), and NaNO3 (1.5 g/L) + beef extract (2.5 g/L) as complex nitrogen (CN). All cultivations were conducted in flasks with constant rotary shaking at 400â??1,000 rpm and 37Â°C.

COL1A2 Barcoding: Bone Species Identification via Shotgun Proteomics

Project description:Species identification of fragmentary bones remains a challenging task in archeology and forensics. A species identification method for such fragmentary bones that has recently attracted interest is the use of bone collagen proteins. We developed a method similar to DNA barcoding that reads collagen protein sequences in bone and automatically determines the species by performing sequence database searches. We tested our method using bone samples from 30 vertebrate species ranging from mammals to fish.

Low-invasive sampling method for taxonomic for the identification of archaeological and paleontological bone by proteomics of their collagens

Project description:Bone collagen is an important organic material for isotopic measurement, radiocarbon and paleoproteomic analyzes, to provide information on diet, dating, taxonomic identification. Current paleoproteomics methods are destructive and require from a few milligrams to several tenths of milligrams of bone for analysis. In many cultures, bones are raw materials for artefact which are conserved in museum which hampers to damage these precious objects during sampling. Here, we describe a minimal sampling method that identifies collagen, taxonomy and post-translational modifications from Holocene and Upper Pleistocene bones dated to 130,000 and 5,000 years ago using dermatological skin tape-discs for sampling. The sampled bone micro-powder were digested following our highly optimized eFASP protocol, then analyzed by MALDI FTICR MS and LC-MS/MS for identifying the genus taxa of the bones. We show that this low-invasive sampling does not deteriorate the bones and achieves results similar to those obtained by destructive sampling. Moreover, this sampling method can be performed at archaeological sites or in museums.

Comparison of bone demineralization protocols for paleoproteomics applications

Project description:Protocols for bone protein extraction adapted for radiocarbon dating were compared for their capability of being used also for paleoproteomics applications. Eight extraction protocols were tested on modern and archaeological bones. Molecular characterization of the extracts was performed by shot-gun proteomics. The effect of each extraction protocol on species identification through database searchnig was evaluated.

M. sedula transcriptional response under heterotrophic, autotrophic, and mixotrophic growth conditions

Project description:To study mixotrophy, it is desirable to have an organism capable of growth in the presence and absence of both organic and inorganic carbon sources, as well as organic and inorganic energy sources. Metallosphaera sedula is an extremely thermoacidophilic archaeon which has been shown to grow in the presence of inorganic carbon and energy source supplements (autotrophy), organic carbon and energy source supplements (heterotrophy), and in the presence of organic carbon and inorganic energy source supplements. The recent elucidation of M. sedulaâ??s inorganic carbon fixation cycle and its genome sequence further facilitate its use in mixotrophic studies. In this study, we grow M. sedula heterotrophically in the presence of organic carbon and energy sources (0.1% tryptone), autotrophically in the presence of inorganic carbon and energy sources (H2 + CO2), and â??mixotrophicallyâ?? in the presence of both organic and inorganic carbon and energy sources (0.1% tryptone + H2 + CO2 ) to characterize the nature of mixotrophy exhibited. Two 3 slide loops joined at equivalent conditions (8 slides total) for Mse cells includes 3 conditions tested in duplicate (biological repeats): heterotrophy (H1 and H2), autotrophy (A1 and A2), and mixotrophy (M1 and M2). Half of an RNA sample for one condition was labeled with Cy3 while the other half was labeled with Cy5. The two differently labeled samples were run on different slides. Each probe is spotted on each slide 5 times (5 replicates; spot intensities for all replicates on slide provided in associated raw data file).

FTIR, XPol, and LC-MS confirm endogenous collagen in Edmontosaurus fossil bone C4PR_LIV

Project description:Reports of proteins in fossilized bones have ignited an on-going debate because previously it was generally assumed that fossilization results in destruction of all organic components. We combine Attenuated Total Reflection (ATR) Fourier Transform InfraRed (FTIR) spectroscopy, cross-polarized light microscopy (XPol), and two variations of Liquid Chromatography Mass Spectrometry (LC-MS), to detect and verify endogenous collagen protein in fossilized bone. Data from an Edmontosaurus dinosaur excavated from Upper Cretaceous strata of the South Dakota Hell Creek Formation were compared with that from thermally decayed modern turkey (Meleagris) bone. The four methods show different evidence for collagen presence in the fossilized bone. ATR-FTIR spectra show a signal for carbonyl (C=O) groups, a repeat moiety in protein amino acid sequences. XPol shows the birefringence of collagen within Meleagris, as well as Edmontosaurus. LC-MS bottom-up proteomics showed m/z agreement between multiple ions from trypsin-digested samples and identified peptide sequences thus far only identified in a hadrosaur. Tandem LC-MS unambiguously identified hydroxyproline, a unique collagen-indicator amino acid, in acid-digested samples from the same.
