WebJul 14, 2024 · Diatoms are promising as natural sources for the production of bioproducts, such as biofuel, pharmaceuticals, and nutraceuticals. For example, fucoxanthin derived from diatoms has antioxidant, anti-inflammatory, anticancer, antidiabetic, antiobesity, and antimetastatic activities [1,2], and EPA could decrease serum triacylglycerol and protect … WebA frustule is the hard and porous cell wall or external layer of diatoms. The frustule is composed almost purely of silica, made from silicic acid, and is coated with a layer of organic substance, which was referred to in the early literature on diatoms as pectin, a fiber most commonly found in cell walls of plants.
