Myxoxanthophyll Myxoxanthophyll Myxoxanthophyll is a carotenoid glycoside pigment present (usually as rhamnosides) in the photosynthetic apparatus of cyanobacteria. It is named after the word ""Myxophyceae"", a former term for cyanobacteria. As a monocyclic xanthophyll, it has a yellowish color. It is required for normal cell wall structure and thylakoid organization in the cyanobacterium "Synechocystis". The pigment is unusual because it is glycosylated on the 2'-OH rather than the 1'-OH position of the molecule. Myxoxanthophyll was first isolated from "Oscillatoria rubenscens" in 1936. The bright red pigment lycopene is the acyclic precursor of all carotenoids in cyanobacteria. In myxoxanthophyll synthesis, lycopene is
Through colour render Through colour render Through colour render is a sand/cement/lime based render that is made from White Portland cement (WOPC) and added pigment to produce a coloured effect that is throughout the body of the material. The pigment is preblended into the product as part of the manufacturing process to produce a prebagged product. Another name for these type of materials is monocouche renders. Various mix designs can be produced in renders according to the published Code of Practice for External Renderings, BS5262 1991. The through colour render market within Europe produces a class 3 mix design as per the Code
