The Actinomycetota are a phylum of mostly Gram-positive bacteria. They can be terrestrial or aquatic. They are of great economic importance to humans because agriculture and forests depend on their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up anew by plants. While this role is also played by fungi, Actinomycetota are much smaller and likely do not occupy the same ecological niche. In this role the colonies often grow extensive mycelia, like a fungus would, and the name of an important order of the phylum, Actinomycetales, reflects that they were long believed to be fungi. Some soil actinomycetota live symbiotically with the plants whose roots pervade the soil, fixing nitrogen for the plants in exchange for access to some of the plant's saccharides. Other species, such as many members of the genus Mycobacterium, are important pathogens.
Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name "krill" comes from the Norwegian word krill, meaning "small fry of fish", which is also often attributed to species of fish.
KPFA is an American listener-funded talk radio and music radio station located in Berkeley, California, broadcasting to the San Francisco Bay Area. KPFA airs public news, public affairs, talk, and music programming. The station signed on the air April 15, 1949, as the first Pacifica Radio station and remains the flagship station of the Pacifica Radio Network.
Micromonosporaceae is a family of bacteria of the class Actinomycetia. They are gram-positive, spore-forming soil organisms that form a true mycelium.
The Chrysler Pacifica is a mid-size crossover produced by Chrysler from 2003 to 2007, for the model years 2004 to 2008.
Eric M. Hammel was a military historian, with a focus on the military campaigns of the United States Marine Corps in the Pacific War, and other military action in World War II as well as military conflicts including the Vietnam War and the Arab-Israeli Conflict. Hammel wrote a series of books about World War II Flying Aces but his most influential book was The Root : The Marines in Beirut, August 1982-February 1984 on the subject of the 1983 Beirut barracks bombings.
Cheung Sha Wan is an area between Lai Chi Kok and Sham Shui Po in New Kowloon, Hong Kong. It is mainly residential to the north and south, with an industrial area in between. Administratively it is part of Sham Shui Po District which also includes Lai Chi Kok.
Jack O'Dell was an African-American activist writer and communist, best known for his role in the Civil Rights Movement of the 1950s and 1960s.
Pacifica State Beach is the southernmost of Pacifica, California's large beaches. It is a 0.75-mile-long (1.21 km) crescent-shaped beach located at the mouth of the San Pedro Valley in downtown Pacifica off State Route 1, in San Mateo County.
Salinosporamide A (Marizomib) is a potent proteasome inhibitor being studied as a potential anticancer agent. It entered phase I human clinical trials for the treatment of multiple myeloma, only three years after its discovery in 2003. This marine natural product is produced by the obligate marine bacteria Salinispora tropica and Salinispora arenicola, which are found in ocean sediment. Salinosporamide A belongs to a family of compounds, known collectively as salinosporamides, which possess a densely functionalized γ-lactam-β-lactone bicyclic core.
Costa Pacifica is a Concordia-class cruise ship for Costa Crociere. She was handed over to Costa Crociere on 29 May 2009. Her sister ships, Costa Concordia and Costa Serena, were launched in 2006 and in 2007, with Costa Favolosa and Costa Fascinosa launched in 2011 and 2012 respectively.
Sporolides A and B are polycyclic macrolides extracted from the obligate marine bacterium Salinispora tropica, which is found in ocean sediment. They are composed of a chlorinated cyclopenta[a]indene ring and a cyclohexenone moiety. They were the second group of compounds isolated from Salinispora, and were said to indicate the potential of marine actinomycetes as a source of novel secondary metabolites. The structures and absolute stereochemistries of both metabolites were elucidated using a combination of NMR spectroscopy and X-ray crystallography.
The salinosporamides are a group of closely related chemical compounds isolated from marine bacteria in the genus Salinispora. They possess a densely functionalized γ-lactam-β-lactone bicyclic core.
Salinispora arenicola is an obligate marine actinomycetes bacterium species. It produces salinosporamide, a potential anti-cancer agent. The type strain is CNH-643T.
Salinispora tropica is an obligate marine actinomycetes bacterium species. It produces salinosporamide A and salinosporamide B, potential anti-cancer agents, as well as the polycyclic macrolides sporolide A and B. The type strain is CNB-440T.
Debromomarinone is a chemical compound isolated from marine actinomycetes.
Salinispora is a genus of obligately aerobic, gram-positive, non-acid-fast bacteria belonging to the family of Micromonosporaceae. They are heterotrophic, non-motile, and obligately grow under high osmotic/ionic-strength conditions. They are the first identified genus of gram-positive bacteria which has a high osmotic/ionic-strength requirement for survival. They are widely abundant in tropical marine sediments and were first identified in 2002. This genus of bacteria has potential biotechnological significance due to their production of novel secondary metabolites which can be used pharmaceutically.
Enterocin and its derivatives are bacteriocins synthesized by the lactic acid bacteria, Enterococcus. This class of polyketide antibiotics are effective against foodborne pathogens including L. monocytogenes, Listeria, and Bacillus. Due to its proteolytic degradability in the gastrointestinal tract, enterocin is used for controlling foodborne pathogens via human consumption.
Pseudoceratina is a genus of sponge within the family Pseudoceratinidae. They are characterized by possession of a dendritic fiber skeleton lacking laminar bark but containing pith. They have been found in a variety of habitats including the Great Barrier reef, the Red Sea, and Jamaica. Sponges of this genus have a microbiome known to produce a variety of chemicals that are used in pharmaceutical and anti-fouling activities. Notably, a species in this genus produces a chemical that is effective in inhibiting the migration of metastatic breast cancer cells.
