Supporting information for the article “Preliminary characterization of the spectral properties of marennine-like pigments from new Haslea strains”

Marennine is a bluish pigment excreted in the seawater by the microalga Haslea Ostrearia. It has interested researchers of different backgrounds such as marine biologists, phytochemists and biochemists because it fixes on the oysters gills and make them green, a phenomenon observed since centuries in the Atlantic French coast near Marenne-Oléron, where the tradition of cultivating oysters is old. Its biological activities have been and are currently studied and many applications are interesting because of its antioxidant, antiangiogenetic and antibacterial activities but also for being a blue natural pigment. During recent sampling campaigns all over the word, new blue diatoms have been discovered and ongoing investigation of genome and frustules appearance are carried out to classify them. A preliminary characterization of the marennine-like pigments that they produce has been carried out, and selected data concerning UV-visible spectrometry, Infrared spectrometry, cyclic voltammetry, elemental composition by Energy-dispersive X-ray spectroscopy (EDX), and proton nuclear magnetic resonance are presented and discussed in the research paper related to this supporting information. Therefore, the data presented in this data paper complete the full paper.

马伦尼色素（Marennine）是由奥氏哈氏藻（Haslea Ostrearia）分泌至海水中的蓝色素。该色素可附着于牡蛎鳃部并使其呈现绿色，这一现象在法国大西洋沿岸马伦-奥莱龙（Marenne-Oléron）附近海域已被观测数百年，该区域拥有悠久的牡蛎养殖传统，因此吸引了海洋生物学家、植物化学家、生物化学家等多领域研究者的关注。其生物学活性早已被研究且至今仍在持续探索，同时由于其具备抗氧化、抗血管生成、抗菌等活性，且作为天然蓝色色素来源，该色素拥有诸多极具潜力的应用场景。近期在全球范围内开展的采样调研中，研究人员发现了多种全新的蓝色硅藻（diatoms），目前正通过基因组分析与硅藻壳（frustules）形态观测对其进行分类鉴定。针对这些硅藻所产生的类马伦尼色素，研究人员已完成初步表征；本支撑信息相关的研究论文中，已呈现并讨论了部分精选数据，涵盖紫外-可见分光光度法（UV-visible spectrometry）、红外光谱法（Infrared spectrometry）、循环伏安法（cyclic voltammetry）、能量色散X射线能谱（Energy-dispersive X-ray spectroscopy，EDX）以及质子核磁共振波谱（proton nuclear magnetic resonance）等检测结果。因此，本数据论文所收录的数据可完整补充该研究论文的核心内容。
