TL;DR: The photosynthetic marine dinoflagellate, Gyrodinium resplendens, was grown axenically and harvested during logarithmic growth for analysis of its lipid-soluble pigments, confirming the presence of β-carotene, peridinin, dinoxanthin and diadinoxanth in as major carotenoids and four new minor xanthophylls are described.
Abstract: The photosynthetic marine dinoflagellate,Gyrodinium resplendens, was grown axenically and harvested during logarithmic growth for analysis of its lipid-soluble pigments. Chlorophylla and 8 carotenoids were isolated from the methanol and acetone extract by column and thin-layer chromatography. Chlorophyllc was isolated by partitioning the total extract between saline aqueous acetone and hexane.

TL;DR: The biosynthetic pathways of all cyanobacterial metabolites have not been elucidated and some groupings have been created based on comparison with other cyanob bacterial compounds, as well as secondary metabolites from other organisms including bacteria, fungi, and microalgae.
Abstract: Publisher Summary This chapter reviews the biogenetic and chemical diversity of secondary metabolites produced by cyanobacteria. The ability of cyanobacteria to biosynthesize complex toxins underscores their innate ability to biosynthesize complex secondary metabolites in general, and more recently, the structural diversity of cyanobacterial metabolites has attracted the attention of scientists searching for new pharmaceutical leads. Today, cyanobacteria are recognized as an exciting resource of new compounds with pharmaceutical potential. In recent years, the biosynthesis of cyanobacterial metabolites has grown to include the identification of the appropriate biosynthetic genes and has even raised the possibility of engineering such genes to produce new “semibiosynthetic” compounds. The biosynthetic pathways of all cyanobacterial metabolites have not been elucidated and some groupings have been created based on comparison with other cyanobacterial compounds, as well as secondary metabolites from other organisms including bacteria, fungi, and microalgae.

TL;DR: More than 300 unusual natural surfactants are described in this review article, including their chemical structures and biological activities.
Abstract: Carotenoid glycosides and isoprenoid glycolipids are of great interest, especially for the medicinal, pharmaceutical, food, cosmetic, flavor, and fragrance industries. These biologically active natural surfactants have good prospects for the future chemical preparation of compounds useful as antimicrobial, antibacterial, and antitumor agents, or in industry. More than 300 unusual natural surfactants are described in this review article, including their chemical structures and biological activities.
