Trace elements and lipidomic datasets of stranding samples in the blubber of Turpsios truncatus from the Yucatan Coast: Association with biological features

ABSTRACT: Trace elements are the result of natural and anthropogenic sources. Some of them are toxic causing alterations in the properties of membranes and produce lipid peroxidation. The dataset presented here is associated with the research article paper entitled “Trace element and lipidomic analysis of bottlenose dolphin blubber from the Yucatan coast: Lipid composition relationships”. In this article, we presented the trace element concentrations found in blubber and their comparison with other studies. Lipidomic characterization of bottlenose dolphin blubber and their association with trace elements and the differences related to biological characteristics. This data provides a correlation analysis between trace element concentrations and lipid species related to biological characteristics. We used Spearman correlation analysis to identify the association with body length and Wicolxon rank-sum test to determine differences in lipids related to stranding code, growth stage and stomach content. The data indicates that Cr, Cd and Zn concentrations were higher compared to other studies. Cr, Co, As and Cd were found in higher concentration in larger organisms. A decrease in some ceramides, sterols, glycerolipids and phosphatydilglyceros related to higher dolphins were found. Decomposition causes a decrease in phosphoethanolamines. Organisms with empty stomachs showed higher concentrations of phosphoethanolamines suggesting a preferential metabolism of energy-rich lipids over structural lipids. The information in these datasets may contribute to understanding the potential associations of trace element, lipid and their associations with biological characteristics.

Bottlenose dolphins (Tursiops truncatus) are found in coastal and estuarine ecosystems where they are in continuous contact with multiple abiotic and biotic stressors in the environment. Due to their role as predators, they can bioaccumulate contaminants and are considered sentinel organisms for monitoring the health of coastal marine ecosystems. The northern zonal coast of the Yucatan peninsula of Mexico has a high incidence of anthropogenic activities. The principal objectives of this study we ...[more]

Project description:Interest in exploiting algae as a biofuel source and the role of nutrient deficiency in inducing triacylglyceride (TAG) accumulation in cells necessitates a strategy to efficiently formulate species-specific culture media that can be easily manipulated. Using the reference organism Chlamydomonas reinhardtii, we tested the hypothesis that modeling trace element supplements on the ionomes of cells would result in optimized cell growth. We characterized the ionomes of multiple wild-type Chlamydomonas strains in various culture conditions and developed a revised trace element solution to parallel our measurements. Comparison of cells growing in the revised supplement versus a traditional trace element solution revealed faster growth rates and higher maximum cell densities with the revised recipe. RNA-seq analysis of cultures growing in the traditional versus revised medium suggest that the variation in transcriptomes was smaller than that found between laboratories using the same supplement. Visual observation did not reveal defects in cell motility or mating efficiency. Ni2+-inducible expression from the CYC6 promoter remained a useful tool, albeit with an increased amount of Ni2+ supplementation due to the introduction of an EDTA buffer system in the revised medium. Equilibrium modeling of the revised supplement predicts less metal precipitation in the revised medium. Other advantages include more facile preparation of trace element stock solutions that can readily be adapted for deficiency studies, a reduction in total chemical use, a more consistent batch-to-batch formulation, and long-term stability (up to 5 years). Under the new growth regime, we analyzed cells growing under different macro- and micronutrient-deficiencies. In N and S deficiency, cells accumulate TAG as well in the new medium as previously demonstrated. Fe and Zn deficiency also induced TAG accumulation as suggested by Nile Red and Bodipy staining. This ionomic approach can be used to efficiently optimize culturing conditions for other algal species to improve growth and assay cell physiology. Sampling of Chlamydomonas CC-1021 (2137) cultivated in TAP medium supplemented with a revised trace element recipe based on ionomic data.
