Rhodopin

	Rhodopin Rhodopin (1,2-dihydro-ψ,ψ-caroten-1-ol) is a carotenoid. It is a major carotenoid of phototropic Phototropism is the growth of an organism in response to a light stimulus.

	Rhodomicrobium Vannielii ''Rhodomicrobium vannielii'' is a Gram-negative, Purple non-sulfur bacteria, purple non-sulfur, motile, Thermophile, thermophilic photoheterotroph bacterium. Phototrophic bacteria are ubiquitous and have been reportedly found in many marine and terrestrial ecosystems. Additionally, they can use light as an energy source and carbon dioxide as a carbon source. Considering this, ''R. vannielii'' is thought to have potential application in anaerobic organism, anaerobic treatment and bioremediation under high temperature conditions as the bacteria was isolated from water samples from a hot spring in Gadek, Malacca, Malaysia using glutamate-malate medium (GMM) and Pfennig's M2 medium. ''R. vannielii'' produces Open-chain compound, acyclic and aliphatic cyclic carotenoids like anhydrorhodovibrin, rhodovibrin, spirilloxanthin and rhodopin. Microbiologic characteristics Morphology Mature ''R. vannielii'' cells are typically ovoid to spherical in shape, do not form intracellular sulfu ...

picture info	Carotenoid Carotenoids (), also called tetraterpenoids, are yellow, orange, and red organic compound, organic pigments that are produced by plants and algae, as well as several bacteria, and Fungus, fungi. Carotenoids give the characteristic color to pumpkins, carrots, parsnips, maize, corn, tomatoes, Domestic Canary, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Carotenoids can be produced from Lipid, fats and other basic organic metabolic building blocks by all these organisms. It is also produced by Endosymbiont, endosymbiotic bacteria in Whitefly, whiteflies. Carotenoids from the diet are stored in the fatty tissues of animals, and exclusively Carnivore, carnivorous animals obtain the compounds from animal fat. In the human diet, Small intestine#Absorption, absorption of carotenoids is improved when consumed with fat in a meal. Cooking carotenoid-containing vegetables in oil and shredding the vegetable both increase carotenoid bioavailability. There are over 1,100 known c ...

picture info	Phototropic Phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Negative phototropism is not to be confused with skototropism which is defined as the growth towards darkness, whereas negative phototropism can refer to either the growth away from a light source or towards the darkness. Most plant shoots exhibit positive phototropism, and rearrange their chloroplasts in the leaves to maximize photosynthetic energy and promote growth.Goyal, A., Szarzyns ...

	Rhodopseudomonas Acidophila ''Rhodoblastus acidophilus'', formerly known as ''Rhodopseudomonas acidophila'', is a gram-negative purple non-sulfur bacteria. The cells are rod-shaped or ovoid, 1.0 to 1.3 μm wide and 2 to 5 μm long. They are motile by means of polar flagella, and they multiply by budding. The photopigments consist of bacteriochlorophyll a and carotenoid Carotenoids (), also called tetraterpenoids, are yellow, orange, and red organic compound, organic pigments that are produced by plants and algae, as well as several bacteria, and Fungus, fungi. Carotenoids give the characteristic color to pumpki ...s of the spirilloxanthin series. All strains can grow either under anaerobic conditions in the light or under microaerophilic to aerobic conditions in the dark.
