Gelidiaceae
The Gelidiaceae is a small family (biology), family of red algae containing eight genera. Many species of this algae are used to make agar. Uses Agar can be derived from many types of red seaweeds, including those from families such as ''Gelidiaceaae'', ''Gracilariaceae'', ''Gelidiellaceae'' and ''Pterocladiaceae''. It is a polysaccharide located in the inner part of the red algal cell wall.

Pterocladiaceae
The Pterocladiaceae is a small family of red algae containing 2 genera of agarophytes. They are found growing on the coast of Portugal, South Africa, India, Japan, Mexico, Chile and New Zealand.Richard Koplik, Karel Cejpek and Jan Velisek From the Gelidiales order, ''Gelidium'' and ''Pterocladia'' , are two of the most widespread genera (which have been often confused for each other) of the Gelidiaceae family. They are separated only by basic features of cystocarps (fruiting structures). The genus ''Pterocladiella'' was later established to segregate from ''Pterocladia'' those species with distinct carposporophyte developmental characters (Santelices and Hommersand 1997). Molecular analyses of taxa within the Gelidiales have identified four major lineages equivalent to ''Gelidiella'', ''Pterocladia'' and ''Pterocladiella'' as sister taxa, and a fourth large clade including species of ''Acanthopeltis'', ''Gelidium'', ''Ptilophora'', ''Porphyroglossum'' and ''Capreolia'' (Fre ...

Gelidiellaceae
The Gelidiellaceae is a small family of red algae containing 5 genera of agarophytes. Members of the family Gelidiellaceace are noted by the lack of hyphae and the lack of sexual reproduction. They have 2 kinds of tetrasporangial sori (either the acerosa-type or the pannosa-type). ''Gelidiella acerosa'' is found worldwide, from Europe, North America, Central America and South America, the Atlantic Islands, Africa, Indian Ocean islands, South west Asia, Asia (including China, Japan and Taiwan), South-east Asia (including Vietnam, Myanmar, Thailand, Singapore, Philippines and Indonesia), Australia, New Zealand and the Pacific islands. Taxonomy It was originally formed in 1961, to hold ''Gelidiella'' and (its single known species, ''Gelidiella acerosa''), as it lacked a medullary hyphae (or rhizines) and lack of sexual phase in life. More species of ''Gelidiella'' from France and the British Isles were added. In 1987, Maggs and Guiry thought that the family should be merged with ...

Gracilariaceae
The Gracilariaceae is a small family of red algae, containing several genera of agarophytes. It has a cosmopolitan distribution, in which 24 species are found in China, six in Great Britain and Ireland, and some in Australia and Chile. They are normally found in intertidal bays, backwaters, and estuaries. The family have been extensively investigated over the last 30 years, and various studies have yielded comprehensive information on their life history, cultivation, taxonomy, and utilization (Bellorin et al. 2002, Rueness 2005). Studies on the structure of their reproductive organs and the phylogenetic relationships among species inferred from rbcL sequence analyses have produced three clades at the genus level, namely ''Gracilaria'', ''Gracilariopsis'', and ''Hydropuntia'' (Gurgel and Fredericq 2004). In 2012, the University of São Paulo, Brazil set up the Gracilariaceae Germplasm Bank, to use molecule markers for the identification of species. Genera As accepted by GBIF ...

Agar
Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from " ogonori" and " tengusa". As found in nature, agar is a mixture of two components, the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae and is released on boiling. These algae are known as agarophytes, belonging to the Rhodophyta (red algae) phylum. The processing of food-grade agar removes the agaropectin, and the commercial product is essentially pure agarose. Agar has been used as an ingredient in desserts throughout Asia and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative; an appetite suppressant; a vegan substitute for gelatin; a thickener for soups; in fruit preserves, ice cream, and other desserts; as a clarifying ...

Friedrich Traugott Kützing
Friedrich Traugott Kützing (8 December 1807 in Ritteburg – 9 September 1893) was a German pharmacist, botanist and phycologist. Despite his limited background in regard to higher education, Kützing made significant scientific contributions. In 1833, he demonstrated differences between diatoms and desmids, thus separating the two groups into families of their own. Also, independent of Charles Cagniard-Latour (1777–1859) and Theodor Schwann (1810–1882), he was among the first to provide comprehensive answers in regard to yeast and the role it played in fermentation. In 1849, he published ''Species Algarum'', a large work that provided descriptions for 6000 species of algae. He is the taxonomic authority of the genera '' Syringodium'' (family Cymodoceaceae) and ''Phlebothamnion'' (family Ceramiaceae). Early life As a young man, he worked in several pharmacies in Germany, also serving as assistant for a few semesters at the chemical-pharmaceutical institute of Fran ...
