Algae is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades. Such organisms range from unicellular microalgae such as Chlorella, Prototheca and the diatoms, to multicellular macroalgae such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton.
Spirulina is the dried biomass of cyanobacteria that can be consumed by humans and animals. The three species are Arthrospira platensis, A. fusiformis, and A. maxima.
Midreshet Ben-Gurion, also known as Midreshet Sde Boker, is a community settlement and an educational center in southern Israel. Located in the Negev next to kibbutz Sde Boker, it falls under the jurisdiction of Ramat HaNegev Regional Council. In 2022 it had a population of 1,938.
Ascophyllum nodosum is a large, common cold water seaweed or brown alga (Phaeophyceae) in the family Fucaceae. Its common names include knotted wrack, egg wrack, feamainn bhuí, rockweed, knotted kelp and Norwegian kelp. It grows only in the northern Atlantic Ocean, along the north-western coast of Europe including east Greenland and the north-eastern coast of North America. Its range further south of these latitudes is limited by warmer ocean waters. It dominates the intertidal zone. Ascophyllum nodosum has been used numerous times in scientific research and has even been found to benefit humans through consumption.
Algaculture is a form of aquaculture involving the farming of species of algae.
Avishay Braverman is an economics professor, politician, and Israeli public figure. Having held senior positions as economist at the World Bank, he was later elected as fifth president of the Ben-Gurion University of the Negev (1990–2006). As a Knesset member on behalf of the Labor Party (2006–2015) he served as Minister of Minority Affairs, Chairman of the Knesset Finance Committee and Chairman of the Knesset Economic Affairs Committee. He is the Israel Prize laureate in 2020 for Lifetime Achievement, for his work as president of Ben-Gurion University.
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
TerraVia Holdings, Inc. was a publicly held biotechnology company in the United States. TerraVia used proprietary technology to transform a range of low-cost plant-based sugars into high-value oils and whole algae ingredients. TerraVia supplied a variety of sustainable algae-based food ingredients to a number of brands, which included Hormel Food Corporation, Utz Quality Foods Inc and enjoy Life Foods. TerraVia also sold its own culinary algae oil under the Thrive Algae Oil brand. In 2017, the firm declared bankruptcy.

Association for Israel Studies (AIS) is an international, interdisciplinary scholarly society devoted to the academic and professional study of modern Israel.
Red algae, or Rhodophyta, make up one of the oldest groups of eukaryotic algae. The Rhodophyta comprises one of the largest phyla of algae, containing over 7,000 recognized species within over 900 genera amidst ongoing taxonomic revisions. The majority of species (6,793) are Florideophyceae, and mostly consist of multicellular, 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.
Nannochloropsis is a genus of algae comprising six known species. The genus in the current taxonomic classification was first termed by Hibberd (1981). The species have mostly been known from the marine environment but also occur in fresh and brackish water. All of the species are small, nonmotile spheres which do not express any distinct morphological features that can be distinguished by either light or electron microscopy. The characterisation is mostly done by rbcL gene and 18S rRNA sequence analysis.
Nasrin Moazami is an Iranian medical microbiologist and biotechnologist. She received her Ph.D. in 1976 from the Faculty of Medicine at Laval University. Moazami is the pioneer of biotechnology and microalgae-based fuels in Iran.
Microalgae or microscopic algae grow in either marine or freshwater systems. They are primary producers in the oceans that convert water and carbon dioxide to biomass and oxygen in the presence of sunlight.
The Spanish Bank of Algae is a national R&D service attached to the Marine Biotechnology Center of the University of Las Palmas de Gran Canaria (ULPGC), which objectives are the isolation, identification, characterization, conservation and provisioning of microalgae and cyanobacteria. It was previously known as the National Bank of Algae (BNA).
Autospores are a type of spores that are produced by algae to enable asexual reproduction and spread. They are non-motile and non-flagellated aplanospores that are generated within a parent cell and have the same shape as the parent cell before their release. Autospores are also known as resting spores. Algae primarily use three different types of spores for asexual reproduction - autospores, zoospores, and aplanospores. Autospores occur in several groups of algae, including Eustigmatophyceae, Dinoflagellates, and green algae. One example of a colonial alga that produces autospores is Dichotomococcus. This alga generates two autospores per reproducing cell, and the autospores escape through a slit in the cell wall and remain attached to the mother cell. Some study on autospores and algae in general include looking into its use for biofuel, animal feed, food supplements, nutraceuticals, and pharmaceuticals.
