A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.
A gelatinous colloid used for culture medium or a stabilizing agent.
A complex mixture of polysaccharides obtained from marine red algae. It is also called agar-agar. Agar is used as an emulsion stabilizer in foods, as a sizing agent in fabrics, and as a solid substrate for the laboratory culture of microorganisms. Agar melts at 100°C (212°F) and when cooled below 44°C (123°F) forms a stiff and transparent gel. Microorganisms are seeded onto and grown (in the laboratory) on the surface of the gel.
Brownish-white seaweed found off the East Indian coast that yields a mucilaginous substance.
In bacteriology and microbiology, a gelatinous substance obtained from red algae that is used as a solidifying agent in preparation of nutrient media for growing microorganisms q.v. and for other purposes.
A culture medium based on an extract of seaweed used for growing microorganisms in laboratories.
A food additive that is extracted from seaweed; it acts as a gelling agent.
Polysaccharide extract of certain seaweeds, which provides a watery gel peculiarly suitable for the solidification of bacteriological culture media, being neither inhibitory nor nutritive in character, not decomposed by most organisms in the course of their growth, and solidifying at about 40° C at the 1-2 per cent strength commonly employed.
A substance used in the laboratory to culture microorganisms.
A gelatinlike substance made from red seaweed. Agar is best known as a solidifying component used to culture bacteria for laboratory analysis.
An extract of certain seaweeds that forms a gel suitable for the solidification of liquid bacteriological culture media. Blood agar is nutrient agar containing 5-10% horse blood, used for the cultivation of certain bacteria or for detecting hemolytic (blood-destroying) activity.
A gelatinous substance made from seaweed, agar is used in preparing culture-media for use in bacteriological laboratories.
A dried mucilaginous product obtained from certain species of algae, especially of the genus Gelidium. Because it is unaffected by bacterial enzymes, it is widely used as a solidifying agent for bacterial culture media. It is used as a laxative because of its great increase in bulk on absorption of water. It is also used by vegetarians when recipes call for gelatin.
A certain substance procured from a type of marine algae, coveted for its culinary versatility in various dishes like desserts, soups, and the like, has been brought to light. This particular element boasts an opalescent pallor, with a partially translucent facade that exhibits neither flavor nor scent. It has also earned the moniker of “Japanese gelatin” in certain circles.
The provided text pertains to a substance that is reminiscent of gelatin, which is derived from a type of red seaweed. Historically, this product was primarily manufactured in countries such as Japan, China, the Soviet Union, and the United States.
Deep within the world of scientific exploration, a remarkable substance emerges—a gel derived from red algae. This extraordinary gel, harnessed from the depths of marine botanicals, finds its purpose in the cultivation of specific disease agents within the laboratory. It serves as a nurturing environment, fostering the growth and study of these elusive entities, contributing to our understanding of pathogens and paving the way for advancements in scientific research and medical diagnostics.
Agar, an extract derived from specific types of seaweeds, possesses properties akin to gelatin. It can be consumed to alleviate constipation by promoting softening and adding volume to feces. Additionally, agar is employed to provide relief from indigestion and heartburn. Furthermore, it serves as a gelling agent in the preparation of growth media for bacterial cultures.
A jelly-like material obtained from seaweed, commonly used in laxatives that add bulk, occasionally mixed with liquid paraffin. It is also used in some treatments for weight loss. The substance fills the stomach without providing any nutrients.
