The Algal Genus Gracilaria in Australia (Division of Fisheries - Report No. 15). The genus Gracilaria was established by Greville in and is the third largest genus in the red algal group with over species worldwide.

Nearly 28 species of Gracilaria have been reported from the Indian coast (Sahoo et al., ). Gracilaria can grow in a wide range of salinities from 5 to 34 ppt, which makes it a common seaweed of brackish water, mangrove swamps, and the sea.

Gracilaria is used as a food in Japanese, Hawaiian, and Filipino cuisine. In Japanese cuisine, it is called ogonori or the Philippines, it is called gulaman and used to make gelatin. In Jamaica, it is known as Irish moss.

Abstract. The genus Gracilaria forms a basis for the multimillion-dollar phycocolloid industry. This genus has a tropical origin and is represented by about species throughout the world.

Despite increasing interest in agar as a commercial product, relatively little is known about the overall reproductive processes in genus the typical life history of Gracilaria follows a Cited by: 1. The genus Rosulabryum (based on Bryum sect. Rosulata) is very diverse in the study area, and Australia is a major centre of speciation for this genus.

These are usually red, green or greenish brown with a three-phase cycle and can be found in tropical and subtropical seas [ 36, 37 ].Cited by: Other articles where Gracilaria is discussed: agar: >Gracilaria (division Rhodophyta).

Best known as a solidifying component of bacteriological culture media, it is also used in canning meat, fish, and poultry; in cosmetics, medicines, and dentistry; as a clarifying agent in brewing and wine making; as a thickening agent in ice cream, pastries.

However, though the commonest species of Gracilaria are recognized in Hawaii by most lay persons, on account of the uses of these species as food, most other species of Gracilaria remain unnoticed or unknown. On the west coast of North America, two species which externally look very much alike are, furthermore, different in their spermatangial Cited by: 3.

Under Gracilaria salicornia, along with the synonyms tabulated herein under non-preferred names in the identity table, Abbott () also listed Gracilaria canaliculata (Kützing) Sonder, following the review of G.

salicornia by Xia (). Withell et al. () describe forms conforming to both G. salicornia and G. canaliculata from western and northern Australia and considered the two as.

The genus Gracilaria represents 60% of the biomass treated in the world. The yield of agar of this kind is very important and can reach up to % (G.

There are more than one hundred species in the world, some of which have very important economic value. Gracilaria is used as food and in the preparation of food products.

Originally and especially in China, Gracilaria species were used as food and as binding material in the preparation of lime for painting walls. Gracilaria Greville genus (Gracilariales, Rhodophyta) is a macroalgae group with more than species of which have been accepted taxonomically.

The notoriety of the red seaweed, Gracilaria tsudae, (Division Rhodophyta, class Rhodophyceae, Order Gracilariales, Family Gracilariaceae), known as chaguan tasi on Guam, was triggered by the death of three Guam residents who ate the seaweed in April The seaweed had been gathered from the reef flats of Tanguisson on the west coast of Guam and was.
