Algae of commercial uses. It is a good medium on which to grow bacteria and fungi, as most microorganisms cannot digest agar. Alginic acid, or alginate, is extracted from brown algae. Its uses range from gelling agents in food, to medical dressings. Alginic acid also has been used in the field of biotechnology as a biocompatible medium for cell encapsulation and cell immobilization. Molecular cuisine is also a user of the substance for its gelling properties, by which it becomes a delivery vehicle for flavours. Between 100,000 and 170,000 wet tons of "Macrocystis" are harvested annually in New Mexico for alginate
Fungi of Australia and leaves. In Australia, 296 smut species from 43 genera have been recorded. Selected mycologists that have made significant contributions to Australian mycology: Many of the books on Australian fungi are listed below: Fungi of Australia The Fungi of Australia form an enormous and phenomenally diverse group, occupying a huge range of freshwater, marine and terrestrial habitats with many ecological roles, for example as saprobes, parasites and mutualistic symbionts of algae, animals and plants, and as agents of biodeterioration. Where plants produce, and animals consume, the fungi recycle, and as such they ensure the sustainability of ecosystems. Knowledge about the
