Nitrogen-depleted Chlorella zofingiensis produces astaxanthin, ketolutein and their fatty acid esters: a carotenoid metabolism study

Studies on Woloszynskioid Dinoflagellates X: Ultrastructure, Phylogeny and Colour Variation in Tovellia rubescens n. sp. (Dinophyceae)

“…; Mulders et al. ; Santos and Mesquita ; Solovchenko ). Although apparently more localized in the cell, the pigment aggregates documented by TEM in T. sanguinea also displayed the roundish outline of lipid globules, suggesting the oil droplets of T. rubescens n. sp.…”

“…The abundant oil droplets found between chloroplast lobes in a red cell of T. rubescens n. sp. are reminiscent of the oil bodies interpreted as the location of accumulated astaxanthin-related compounds in cells of green algae associated with red snow (Remias et al 2016) and in species of the industrially important genera Chlorella Beijerinck and Haematococcus Flotow (Bar et al 1995;Mulders et al 2015;Santos and Mesquita 1984;Solovchenko 2015). Although apparently more localized in the cell, the pigment aggregates documented by TEM in T. sanguinea also displayed the roundish outline of lipid globules, suggesting the oil droplets of T. rubescens n. sp.…”

Microalgal Classification

“…In contrast, the freshwater alga H. pluvialis is used to produce astaxanthin. Other potential producers of astaxanthin are the freshwater algae Chlorella zofingiensis (Mulders et al, 2014) and Chlorococcum sp. Astaxanthin, a strong antioxidant, is used as a nutritional supplement and anticancer agent, and exhibits preventive properties for diabetes, cardiovascular diseases, and neurodegenerative disorders, and also stimulates immunization (Ambati et al, 2014;Guedes et al, 2011).…”

Preliminary UHPLC–PDA–ESI-MS screening of light-accelerated autoxidation products of the tetrapyrrole biliverdin

“…RP-UHPLC-PDA-ESI-MS was performed as described elsewhere (Mulders et al, 2014), with the following modifications: The eluents used were the following: 1% (v/v) acetonitrile in millipore water (A) and acetonitrile (B) both containing 0.10% (v/v) formic acid as a mobile phase modifier. The elution program was started at 95% (v/v) A, 5% (v/v) B and followed by a 0-20 min -linear gradient to 100% (v/v) B; 20-22 min -isocratic at 100% (v/v).…”
