Abstract
The soft-shelled turtle is a commercially aquatic species in Asian countries, which serves as an important source of collagen with high nutritional and medicinal value, so it is of great significance to distinguish soft-shelled turtle derived collagen from others or adulterations. In this work, peptidomics analysis based on post-translational modification (PTM) assay was used to discover specific peptide biomarkers of soft-shelled turtle gelatin (STG). In total eight specific sequences and 74 peptides with different PTM types were screened out, and seven peptides with good signal responses and STG specificity were selected and validated as STG-specific peptide biomarkers. These peptide biomarkers could be used for distinguishing STG from other animal gelatins, and applied for ensuring the quality of collagens or gelatins from soft-shelled turtle with authenticity and traceability.

Abstract
Background Chinese soft-shell turtle (Pelodiscus sinensis) is an important commercial species for their high nutritional value and unique taste, but it has been a vulnerable species due to habitat loss. In this study, homologous juvenile turtles were allocated to lake, pond and paddy field to investigate the habitat effects on turtles. Results The growth, morphology and gut microbial communities were monitored during the 4 months cultural period. It showed higher growth rate of turtles in paddy field and pond. The appearance, visceral coefficients, gut morphology and microbial communities in turtles were distinct among different habitats. The microbial community richness on Chao1 was obviously lower in initial turtle guts from greenhouses, whereas it was relative higher in turtle guts sampled from paddy fields than ponds and lake. Significant differences on dominant microbes were found among initial and subsequent samples from different habitats. Firmicutes was the most abundant phylum in the guts of turtles sampled from the greenhouse initially, while Proteobacteria was the most abundant phylum after cultivation in different habitats, followed by Bacteroidetes. The microbial composition were distinct in different habitats at 60d, and the appearance of dominant phyla and genera was more driven by sampling time than habitats at 120d. Both the sampling time and habitats affected the appearance of dominant phyla and genera during the cultivation. The functional predictions indicated that both habitat type and sampling time had significant effects on metabolic pathways, especially amino acid and carbohydrate metabolism. Conclusions The turtles could adapt to natural lakes, artificial ponds and paddy fields. The gut microbial abundance was different among the habitats and sampling time. The species of microbes were significantly more diverse in paddy field specimens than in those from ponds and lakes. Rice-turtle coculture is a potential ecological and economic farming mode that plays important roles in wild turtle protection and food security.

Abstract
A simple and green approach was developed to extract the pepsin soluble collagen-II using the ultra-sonication treatment that significantly increased the extracted yield from chicken sternal cartilage (CSC). The pretreatment of raw CSC had positive effects on proximate composition. The maximum yield of pepsin soluble collagen was obtained by ultrasound treatment time 36 min (UPSCII36; 3.37 g) as compared to non-ultrasound treated pepsin soluble collagen at zero minutes (UPSCII0; 1.73 g) (control). The amino acid profile, differential scanning calorimetry (DSC) of UPSC were significantly (p < 0.05) improved by the application of ultrasound. The results showed the secondary structure of ultrasound treated PSC-II was partially altered as the ultra-sonication time prolonged. Moreover, ultrasound-treated collagen had superior functional properties such as water, oil absorption capacity, water holding capacity, foaming and emulsifying properties than non-ultrasound treated collagen. The poultry by-products CSC would be a potential source of land animal collagen-II. The utilization of ultrasound for the extraction of pepsin soluble collagen-II is a good alternative technology to expand the application of collagen at industrial level.

Vibrio cholerae Colonization of Soft-Shelled Turtles. Appl Environ Microbiol 2017; 83:AEM.00713-17.

Abstract
Vibrio cholerae is an important human pathogen and environmental microflora species that can both propagate in the human intestine and proliferate in zooplankton and aquatic organisms. Cholera is transmitted through food and water. In recent years, outbreaks caused by V. cholerae-contaminated soft-shelled turtles, contaminated mainly with toxigenic serogroup O139, have been frequently reported, posing a new foodborne disease public health problem. In this study, the colonization by toxigenic V. cholerae on the body surfaces and intestines of soft-shelled turtles was explored. Preferred colonization sites on the turtle body surfaces, mainly the carapace and calipash of the dorsal side, were observed for the O139 and O1 strains. Intestinal colonization was also found. The colonization factors of V. cholerae played different roles in the colonization of the soft-shelled turtle's body surface and intestine. Mannose-sensitive hemagglutinin (MSHA) of V. cholerae was necessary for body surface colonization, but no roles were found for toxin-coregulated pili (TCP) or N-acetylglucosamine-binding protein A (GBPA). Both TCP and GBPA play important roles for colonization in the intestine, whereas the deletion of MSHA revealed only a minor colonization-promoting role for this factor. Our study demonstrated that V. cholerae can colonize the surfaces and the intestines of soft-shelled turtles and indicated that the soft-shelled turtles played a role in the transmission of cholera. In addition, this study showed that the soft-shelled turtle has potential value as an animal model in studies of the colonization and environmental adaption mechanisms of V. cholerae in aquatic organisms.IMPORTANCE Cholera is transmitted through water and food. Soft-shelled turtles contaminated with Vibrio cholerae (commonly the serogroup O139 strains) have caused many foodborne infections and outbreaks in recent years, and they have become a foodborne disease problem. Except for epidemiological investigations, no experimental studies have demonstrated the colonization by V. cholerae on soft-shelled turtles. The present studies will benefit our understanding of the interaction between V. cholerae and the soft-shelled turtle. We demonstrated the colonization by V. cholerae on the soft-shelled turtle's body surface and in the intestine and revealed the different roles of major V. cholerae factors for colonization on the body surface and in the intestine. Our work provides experimental evidence for the role of soft-shelled turtles in cholera transmission. In addition, this study also shows the possibility for the soft-shelled turtle to serve as a new animal model for studying the interaction between V. cholerae and aquatic hosts.

Abstract
Collagen is the main structural protein of various connective tissues in animals and naturally plays an important role within the body. It is increasingly used within certain areas, such as medicine, citology and cosmetology. The soft-shelled turtle (Pelodiscus sinensis) is a commercially important aquatic species rich in collagen. In this study, a novel collagen gene fragment of 756 bp, which encodes 252 deduced amino acid residues, including 25 conserved Gly-X-Y motifs, was cloned from a soft-shelled turtle. Recombinant soft-shelled turtle collagen (rSTC) was stably expressed in Escherichia coli Rosetta and purified by His GraviTrap affinity columns. The antioxidant activities of rSTC were measured using hydroxyl and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. The results showed that rSTC quenched the free radicals in a dose-dependent manner. The hydroxyl radical scavenging activity (HRSA) of rSTC was 98.9 % at a concentration of 3 mg/mL. At a concentration of 5 mg/mL, rSTC exhibited a DPPH radical scavenging activity of 32.7 %. At the tested concentrations, rSTC exhibited higher HRSA and lower DPPH radical scavenging activity.

Abstract
The soft-shelled turtle Pelodiscus sinensis is a high-profile turtle species because of its nutritional and medicinal value in Asian countries. However, little is known about the genes that are involved in formation of their nutritional quality traits, especially the molecular mechanisms responsible for unsaturated fatty acid and collagen biosynthesis. In the present study, the transcriptomes from six tissues from Pelodiscus sinensis were sequenced using an Illumina paired-end sequencing platform. We obtained more than 47 million sequencing reads and 73954 unigenes with an average size of 754 bp by de-novo assembly. In total, 55.19% of the unigenes (40814) had significant similarity with proteins in the National Center of Biotechnology Information (NCBI) non-redundant protein database and Swiss-Prot database (E-value <10(-5)). Of these annotated unigenes, 9156 and 11947 unigenes were assigned to 52 gene ontology categories (GO) and 25 clusters of orthologous groups (COG), respectively. In total, 26496 (35.83%) unigenes were assigned to 242 pathways using the Kyoto Encyclopedia of Genes and Genomes pathway database (KEGG). In addition, we found a number of highly expressed genes involved in the regulation of P. sinensis unsaturated fatty acid biosynthesis and collagen formation, including desaturases, growth factors, transcription factors, and extracellular matrix components. Our data represent the most comprehensive sequence resource available for the Chinese soft-shelled turtle and could provide a basis for new research on this turtle as well as the molecular genetics and functional genomics of other terrapins. To our knowledge, we report for the first time, the large-scale RNA sequencing (RNA-Seq) of terrapin animals and would enrich the knowledge of turtles for future research.

Abstract
There have been concerns regarding the suitability of bovine collagen as a biomaterial since the emergence of bovine spongiform encephalopathy. Consequently, collagens from other species may be used if they can meet appropriate standards, including negligible or lack of immunogenicity. In this study, the potential immunogenicity of both monomeric and pepsin-solubilized chicken collagens have been compared with a commercial, pepsin-solubilized bovine collagen that is approved for biomedical implantation. All collagens were poor immunogens compared with ovalbumin. No IgE responses were detected in sera of three strains of mice, and no hypersensitivity reactions were found in guinea pigs in maximization and Buehler tests. IgG(1) antibodies were found although the titre was substantially lower than against ovalbumin. All responses in mice and rabbits were found only when immunizations were performed with adjuvant, and after multiple injections over a long period of time. The response from the monomeric chicken collagen was less than for pepsin-solubilized collagens. Collagen sponges prepared from the two chicken collagen preparations both supported the attachment and growth of mouse fibroblasts. These data indicate that chicken collagen, particularly when monomeric, may be useful in certain biomedical applications.
