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.

马雷尼纳是一种由微藻Haslea Ostrearia分泌至海水中的蓝色色素。因其能附着于牡蛎的鳃部并使其变绿，这一现象自数百年前在法国大西洋沿岸的Marenne-Oléron附近即可观察到，该地区牡蛎养殖历史悠久，因此吸引了来自不同领域的学者，如海洋生物学家、植物化学家和生物化学家们的关注。该色素的生物活性已被研究并持续研究，其多种应用因具有抗氧化、抗血管生成和抗菌活性以及作为天然蓝色颜料而备受瞩目。在最近全球范围内的采样活动中，发现了新的蓝色硅藻，对其基因组及壳体形态的研究正在进行，以对其进行分类。已对它们产生的类似马雷尼纳色素进行了初步表征，并呈现了相关的数据，包括紫外-可见光谱学、红外光谱学、循环伏安法、通过能量色散X射线光谱法（EDX）进行的元素组成分析以及质子核磁共振数据，这些数据在相关的研究论文中得到了展示和讨论。因此，本数据论文中呈现的数据是对完整论文的补充。
