Gelidium is a genus of thalloid red algae comprising 134 species. Its members are known by a number of common names. [note 1] Specimens can reach around 2–40 cm (0.79–16 in) in size. Branching is irregular, or occurs in rows on either side of the main stem. Gelidium produces tetraspores. Many of the algae in this genus are used to make agar. [1] .

Gelidium is a small, slow growing plant, and although efforts to cultivate it in tanks and ponds have been biologically successful, it has so far proved to be uneconomic. Gelidium grows best where there is rapid water movement: the eulittoral and sublittoral zones.

Gelidium amansii, also known as by its Korean name umutgasari, [1] is an economically important species of red algae commonly found and harvested in the shallow coast (3 to 10 m or 10 to 33 ft of depth below the water) of many East Asian countries including North and South Korea, China, Japan, Singapore, and northeast Taiwan.

…primarily from the red algae Gelidium and 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…

Gelidium sesquipedale is a commercially important species of red algae. It is a thalloid seaweed, branching on a single axis. A clonal species, it grows in stands on rocky bottoms in the subtidal zone in areas with high water movement and exposed to wave action.

May 29, 2023 · Gelidium is one of the agar-producing red macroalgae and has been used as sea vegetable, human food and as traditional herb medicine in East Asian countries. Gelidium has been used as a food ingredient for centuries by boiling it …

The meaning of GELIDIUM is a genus of red algae (family Gelidiaceae) having cartilaginous terete or compressed much-branched fronds and cystocarps immersed in swollen branchlets and being important sources of agar.

In the present work, Gelidium corneum was evaluated regarding its potential as a source of antimicrobial compounds through a green extraction approach, aiming to develop new therapeutic alternatives for dysbiosis-related skin disorders.

Gelidium is used for preparing agar-agar, especially in Japan. Gelidium is found in negligible quantities in the USSR in the Sea of Japan and the Black Sea.
