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 ...

Red Algae Families
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–750 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the ...

Polysaccharide
Polysaccharides (), or polycarbohydrates, are the most abundant carbohydrates found in food. They are long-chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages. This carbohydrate can react with water (hydrolysis) using amylase enzymes as catalyst, which produces constituent sugars (monosaccharides or oligosaccharides). They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch, glycogen and galactogen and structural polysaccharides such as hemicellulose and chitin. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more t ...

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 ...

Red Algae
Red algae, or Rhodophyta (, ; ), make up one of the oldest groups of eukaryotic algae. The Rhodophyta comprises one of the largest Phylum, phyla of algae, containing over 7,000 recognized species within over 900 Genus, genera amidst ongoing taxonomic revisions. The majority of species (6,793) are Florideophyceae, and mostly consist of multicellular, ocean, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, no terrestrial species exist, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. Red algae form a distinct group characterized by eukaryotic cells without flagella and centrioles, chloroplasts without external endoplasmic reticulum or unstack ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
