Shellfish, in colloquial and fisheries usage, are exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some are found in freshwater. In addition, a few species of land crabs are eaten, for example Cardisoma guanhumi in the Caribbean. Shellfish are among the most common food allergens.
Candida is a genus of yeasts. It is the most common cause of fungal infections worldwide and the largest genus of medically important yeasts.
Kaikō was a remotely operated underwater vehicle (ROV) built by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for exploration of the deep sea. Kaikō was the second of only five vessels ever to reach the bottom of the Challenger Deep, as of 2019. Between 1995 and 2003, this 10.6 ton unmanned submersible conducted more than 250 dives, collecting 350 biological species, some of which could prove to be useful in medical and industrial applications. On 29 May 2003, Kaikō was lost at sea off the coast of Shikoku Island during Typhoon Chan-Hom, when a secondary cable connecting it to its launcher at the ocean surface broke.
Bacillus safensis is a gram-positive, spore-forming, and rod bacterium, originally isolated from a spacecraft in Florida and California. B. safensis could have possibly been transported to the planet Mars on spacecraft Opportunity and Spirit in 2004. There are several known strains of this bacterium, all of which belong to the Bacillota phylum of Bacteria. This bacterium also belongs to the large, pervasive genus Bacillus. B. safensis is an aerobic chemoheterotroph and is highly resistant to salt and UV radiation. B. safensis affects plant growth, since it is a powerful plant hormone producer, and it also acts as a plant growth-promoting rhizobacteria, enhancing plant growth after root colonization. Strain B. safensis JPL-MERTA-8-2 is the only bacterial strain shown to grow noticeably faster in micro-gravity environments than on the Earth surface.
The Coon Creek Formation or Coon Creek Tongue is a geologic unit and Konservat-Lagerstätte located in western Tennessee and extreme northeast Mississippi. It is a sedimentary sandy marl deposit, Late Cretaceous (Maastrichtian) in age, about 70 million years old. The formation is renowned for its pristine fossils of Late Cretaceous marine invertebrates, including gastropods, bivalves, decapod crustaceans, and ammonites, particularly at Coon Creek in McNairy County, Tennessee, which the formation is named for. It is also known for producing fosslis of marine vertebrates, such as mosasaurs and plesiosaurs. Notable fossils from this formation is the gastropod Turritella, the bivalve Pterotrigonia thoracica, as well as other fossils such as crabs.
Kluyveromyces marxianus in ascomycetous yeast and member of the genus, Kluyveromyces. It is the sexual stage of Atelosaccharomyces pseudotropicalis also known as Candida kefyr. This species has a homothallic mating system and is often isolated from dairy products.
Sulfurimonas is a bacterial genus within the class of Campylobacterota, known for reducing nitrate, oxidizing both sulfur and hydrogen, and containing Group IV hydrogenases. This genus consists of four species: Sulfurimonas autorophica, Sulfurimonas denitrificans, Sulfurimonas gotlandica, and Sulfurimonas paralvinellae. The genus' name is derived from "sulfur" in Latin and "monas" from Greek, together meaning a “sulfur-oxidizing rod”. The size of the bacteria varies between about 1.5-2.5 μm in length and 0.5-1.0 μm in width. Members of the genus Sulfurimonas are found in a variety of different environments which include deep sea-vents, marine sediments, and terrestrial habitats. Their ability to survive in extreme conditions is attributed to multiple copies of one enzyme. Phylogenetic analysis suggests that members of the genus Sulfurimonas have limited dispersal ability and its speciation was affected by geographical isolation rather than hydrothermal composition. Deep ocean currents affect the dispersal of Sulfurimonas spp., influencing its speciation. As shown in the MLSA report of deep-sea hydrothermal vents Campylobacterota, Sulfurimonas has a higher dispersal capability compared with deep sea hydrothermal vent thermophiles, indicating allopatric speciation.
Alcanivorax pacificus is a pyrene-degrading marine gammaproteobacterium. It is of the genus Alcanivorax, a group of marine bacteria known for degrading hydrocarbons. When originally proposed, the genus Alcanivorax comprised six distinguishable species. However, A. pacificus, a seventh strain, was isolated from deep sea sediments in the West Pacific Ocean by Shanghai Majorbio Bio-pharm Technology Co., Ltd. in 2011. A. pacificus’s ability to degrade hydrocarbons can be employed for cleaning up oil-contaminated oceans through bioremediation. The genomic differences present in this strain of Alcanivorax that distinguish it from the original consortium are important to understand to better utilize this bacteria for bioremediation.
Sulfurovum lithotrophicum is a species of bacteria, the type species of its genus. It is a sulfur-oxidizing chemolithoautotroph within the ε-Proteobacteria isolated from Okinawa Trough hydrothermal sediments. It is mesophilic and also oxidises thiosulfate. It is a gram-negative, non-motile and coccoid to oval-shaped bacterium. The type strain is 42BKTT.
Hanseniaspora guilliermondii is a species of yeast in the family Saccharomycetaceae. In its anamorph form, it is called Kloeckera apis.
Streptomyces nanhaiensis is a bacterium species from the genus of Streptomyces which has been isolated from deep sea sediments from the northern South China Sea in China.
Lachancea thermotolerans is a species of yeast.
Janibacter is a genus of Gram positive, nonmotile, non-sporeforming bacteria. The genus name is derived from the two-faced Roman god Janus, referring to the fact that the cells of the original strain could be rod-shaped or coccoid.
Kazachstania yasuniensis is a recently isolated yeast. This organism is part of the genus Kazachstania, which can be found in a large variety of habitats such as fermented foods, animals, wastewater, et cetera.
Oceanobacillus profundus is a gram positive, rod shaped, halophilic bacteria of the family Bacillaceae. Oceanobacillus profundus was isolated from the surface of a sediment core sample of the Tsushima Basin of the Sea of Japan, Korea, and from marine sponge of Saint Martin's island of the Bay of Bengal, Bangladesh. The type strain is CL-MP28T. Sponge associated Oceanobacillus profundus strain CS 9 was highly salt tolarent.
Oceanobacillus pacificus is a gram positive, rod shaped, halophilic bacteria of the family Bacillaceae. Oceanobacillus pacificus species was isolated from deep-sea sediment core of the South Pacific Gyre and from marine sponge of Saint Martin's island of the Bay of Bengal, Bangladesh. The type strain is XH204T.
Naganishia vishniacii is an extremophile fungus originally isolated as a yeast from soil samples in the dry valleys of Antarctica. The species grows at 4 degrees Celsius and below but not at 26 degrees Celsius and above. Visually it is characterized as a cream mass in culture. It is nonfermentative and assimilates glucose, maltose, melezitose, trehalose, and xylose. Molecular research, based on cladistic analysis of DNA sequences, shows that the species does not belong in the Cryptococcaceae.
Hanseniaspora occidentalis is a species of yeast in the family Saccharomycetaceae. In its anamorph form, it was called Kloeckera javanica.
