Sphingomonadaceae
Sphingomonadaceae are a gram-negative bacterial family of the Alphaproteobacteria. An important feature is the presence of sphingolipids (mainly 2′-hydroxymyristol dihydrosphingosine 1-glucuronic acid, "SGL-1") in the outer membrane of the cell wall. The cells are ovoid or rod-shaped. Others are also pleomorphic, i.e. the cells change the shape over time. Some species from Sphingomonadaceae family are dominant components of biofilms. Energy source While most species within Sphingomonadaceae family are heterotrophic, some are phototrophic. Function Some species of Sphingomonadaceae are known to degrade some aromatic compounds. This makes the bacteria of interest to environmental remediation. The diverse metabolic capacity of genera within the ''Sphingomonadaceae'' family, such as '' Sphingobium'', '' Novosphingobium'', and '' Sphingopyxis'' enable these genera to adapt to and be abundant in the presence of Bisphenol A.

Sphingobium
Sphingobium species are different from other sphingomonads in that they are commonly isolated from soil; however, ''Sphingobium yanoikuyae'' was isolated from a clinical specimen. They can degrade a variety of chemicals in the environment such as aromatic and chloroaromatic compounds, phenols like nonylphenol and pentachlorophenol, herbicides such as (RS)-2-(4-chloro-2-methylphenoxy) propionic acid and hexachlorocyclohexane, and polycyclic aromatic hydrocarbon A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings and the three-ring compounds anthracene and phenanthrene. ...s.

Sphingomonas Phyllosphaerae
Sphingomonas phyllosphaerae is a species of bacteria. It was first isolated from the phyllosphere of a leguminous tree, ''Acacia caven'', in central Argentina. It is Gram-negative, strictly aerobic, rod-shaped and motile Motility is the ability of an organism to move independently, using metabolic energy. Definitions Motility, the ability of an organism to move independently, using metabolic energy, can be contrasted with sessility, the state of organisms th .... Its type strain is FA2(T) (=LMG 21958(T)=CECT 5832(T)).

Sphingolipids
Sphingolipids are a class of lipids containing a backbone of sphingoid bases, a set of aliphatic amino alcohols that includes sphingosine. They were discovered in brain extracts in the 1870s and were named after the mythological sphinx because of their enigmatic nature. These compounds play important roles in signal transduction and cell recognition. Sphingolipidoses, or disorders of sphingolipid metabolism, have particular impact on neural tissue. A sphingolipid with an R group consisting of a hydrogen atom only is a ceramide. Other common R groups include phosphocholine, yielding a sphingomyelin, and various sugar monomers or dimers, yielding cerebrosides and globosides, respectively. Cerebrosides and globosides are collectively known as glycosphingolipids. Structure The long-chain bases, sometimes simply known as sphingoid bases, are the first non-transient products of '' de novo'' sphingolipid synthesis in both yeast and mammals. These compounds, specifically known as phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphingomonas
''Sphingomonas'' was defined in 1990 as a group of Gram-negative, rod-shaped, chemoheterotrophic, strictly aerobic bacteria. They possess ubiquinone 10 as their major respiratory quinone, contain glycosphingolipids (GSLs), specifically ceramide, instead of lipopolysaccharide (LPS) in their cell envelopes, and typically produce yellow-pigmented colonies. The GSL serves to protect the bacteria from antibacterial substances. Unlike most Gram-negative bacteria, ''Sphingomonas'' carries endotoxins and has a hydrophobic surface characterized by the short nature of the GSL's carbohydrate portion. By 2001, the genus included more than 20 species that were quite diverse in terms of their phylogenetic, ecological, and physiological properties. As a result, ''Sphingomonas'' was subdivided into different genera: ''Sphingomonas'', '' Sphingobium'', ''Novosphingobium'', '' Sphingosinicella'', and ''Sphingopyxis''. These genera are commonly referred to collectively as sphingomonads. Distinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microbiological Culture
A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as a research tool in molecular biology. The term ''culture'' can also refer to the microorganisms being grown. Microbial cultures are used to determine the type of organism, its abundance in the sample being tested, or both. It is one of the primary diagnostic methods of microbiology and used as a tool to determine the cause of infectious disease by letting the agent multiply in a predetermined medium. For example, a throat culture is taken by scraping the lining of tissue in the back of the throat and blotting the sample into a medium to be able to screen for harmful microorganisms, such as ''Streptococcus pyogenes'', the causative agent of strep throat. Furthermore, the term culture is more generally used informall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
