All new Organic Agar! Ultra high quality Gelidium Agar makes this a media must have for any lab. Neutral viscosity makes this an optimal choice agar for fully automated setups, pipettes, and standard media bottles. Gelidium is a genus of thalloid red algae comprising 124 species. Gelidium is a higher-grade agar used for Petri Dishes that support bacteria and fungi cultures in research projects.
Two genera, Gelidium and Gracilaria, account for most of the raw materials used for the extraction of agar. Extraction of Gelidium species gives the higher quality agar, as measured by the strength of a jelly formed by a 1.5% solution. All Gelidium used for commercial agar extraction comes from natural resources, principally from France, Indonesia, the Republic of Korea, Mexico, Morocco, Portugal, USA and Spain. Depending on the species, it can be found in water from 2 to 20 m in depth. Gelidium prefers rocky areas with steep slopes and is rarely found on muddy or sandy bottoms. It prefers partial shade and may be bleached by full intensity light in tropical latitudes. It usually grows best at 15–20°C but can tolerate higher temperatures. It can survive in low-nutrient conditions and some species adapt to low or high salinity.
