Brachybacterium Endophyticum
''Brachybacterium endophyticum'' is a species of Gram positive, facultatively anaerobic, halotolerant, cream-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from surface-sterilized bark of Scutellaria baicalensis from Guizhou, China. The species was first proposed in 2018, and the name refers to the fact that the bacteria is likely an endophyte. The optimum growth temperature for ''B. endophyticum'' is 30 °C, but can grow in the 4-37 °C range. The pH optimum is 8.0, and can grow in the 5.0-11.0 range. The cells are halotolerant Halotolerance is the adaptation of living organisms to conditions of high salinity. Halotolerant species tend to live in areas such as hypersaline lakes, coastal dunes, saline deserts, salt marshes, and inland salt seas and springs. Halophiles are ..., and can grow in NaCl salt concentrations up to 15%. References Micrococcales Bacteria descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram Positive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. The Gram stain is used by microbiologists to place bacteria into two main categories, gram-positive (+) and gram-negative (−). Gram-positive bacteria have a thick layer of peptidoglycan within the cell wall, and gram-negative bacteria have a thin layer of peptidoglycan. Gram-positive bacteria retain the crystal violet stain used in the test, resulting in a purple color when observed through an optical microscope. The thick layer of peptidoglycan in the bacterial cell wall retains the stain after it has been fixed in place by iodine. During the decolorization step, the decolorizer removes crystal violet from all other cells. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage deg ...

Bacterium
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in mutualistic, commensal and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scutellaria Baicalensis
''Scutellaria baicalensis'', with the common name Baikal skullcap or Chinese skullcap, is a species of flowering plant in the family Lamiaceae. Distribution The plant is native to China, Korea, Mongolia, and Russia in the Russian Far East and Siberia. Traditional Chinese medicine It is one of the 50 fundamental herbs used in traditional Chinese medicine, where it has the name ''huángqín'' (). As a Chinese traditional medicine, ''huang qin'' usually refers to the dried root of ''S. baicalensis'' Georgi, ''S. viscidula'' Bge., ''S. amoena'' C.H. Wright, and ''S. ikoninkovii'' Ju. Phytochemicals Several phytochemicals have been isolated from the root; baicalein, baicalin, wogonin, norwogonin, oroxylin A and β-sitosterol are the major ones. Names As the term 'skullcap' is applied to over 200 plant varieties, the scientific name is used. Sometimes, ''Scutellaria lateriflora'' (North American skullcap) is mistaken for ''S. baicalensis''. Adverse effects There have been sev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endophyte
An endophyte is an endosymbiont, often a bacterium or fungus, that lives within a plant for at least part of its life cycle without causing apparent disease. Endophytes are ubiquitous and have been found in all species of plants studied to date; however, most of the endophyte/plant relationships are not well understood. Some endophytes may enhance host growth and nutrient acquisition and improve the plant's ability to tolerate abiotic stresses, such as drought, and decrease biotic stresses by enhancing plant resistance to insects, pathogens and herbivores. Although endophytic bacteria and fungi are frequently studied, endophytic archaea are increasingly being considered for their role in plant growth promotion as part of the core microbiome of a plant. History Endophytes were first described by the German botanist Johann Heinrich Friedrich Link in 1809. They were thought to be plant parasitic fungi and they were later termed as "microzymas" by the French scientist Béchamp. The ...

Halotolerance
Halotolerance is the adaptation of living organisms to conditions of high salinity. Halotolerant species tend to live in areas such as hypersaline lakes, coastal dunes, saline deserts, salt marshes, and inland salt seas and springs. Halophiles are also organisms that not only live in highly saline environments but also ''require'' the salinity to survive. Halotolerant organisms on the other hand (belonging to different domains of life) can grow under saline conditions, but do not require elevated concentrations of salt for growth. Halophytes are salt-tolerant higher plants. Halotolerant microorganisms are of considerable biotechnological interest. Applications Fields of scientific research relevant to halotolerance include biochemistry, molecular biology, cell biology, physiology, ecology, and genetics. An understanding of halotolerance can be applicable to areas such as arid-zone agriculture, xeriscaping, aquaculture (of fish or algae), bioproduction of desirable compounds (su ...
