Rhizobium Bangladeshense
''Rhizobium bangladeshense'' is a gram-negative bacterium which was isolated from root nodules of lentils in Bangladesh. Description ''Rhizobium bangladeshense'' are rod-shaped bacteria which live in soil, particularly on the root nodules of plants. They require oxygen, and do not form spores. When ''R. bangladeshense'' grow on agar plates, they form colonies which are circular, convex and creamy white on YEMA medium. Strains can tolerate pH values between 5.5 and 10. Strains that have been studied are sensitive to ampicillin, resistant to kanamycin and nalidixic acid, and grow well in YEMA medium containing 0.5% NaCl. Strains do not tolerate tetracycline and do not show any growth on LB medium. ''Rhizobium bangladeshense'' can utilize a variety of nutrients for growth, including D-maltose, D-trehalose, D-cellobiose, gentiobiose, sucrose, D-raffinose, α-D-glucose, D-turanose, α-D lactose, D-fructose, β-methyl-D-glucoside, salicin, N-acetyl-D-galactosamine, D-sor ...

Gram-negative Bacterium
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lincomycin
Lincomycin is a lincosamide antibiotic that comes from the actinomycete ''Streptomyces lincolnensis''. A related compound, clindamycin, is derived from lincomycin by using thionyl chloride to replace the 7-hydroxy group with a chlorine atom with inversion of chirality. It was released for medical use in September 1964. Uses Although similar in antibacterial spectrum and mechanism of action to macrolides, lincomycin is also effective against other organisms including actinomycetes and some species of '' Mycoplasma'' and ''Plasmodium''. However, because of its adverse effects and toxicity, it is rarely used today and reserved for patients allergic to penicillin or where bacteria have developed resistance. Clinical pharmacology Intramuscular administration of a single dose of 600 mg of Lincomycin produces average peak serum levels of 11.6 µg/mL at 60 min, and maintains therapeutic levels for 17 h to 20 h, for most susceptible gram-positive organis ...

Khulna District
Khulna District ( bn, খুলনা জেলা , ''Khulna Jela'' also ''Khulna Zila'') is a district of Bangladesh. It is located in the Khulna Division. It is bordered on the north by the Jessore District and the Narail District, on the south by the Bay of Bengal, on the east by the Bagerhat District, and on the west by the Satkhira District.

Lens Culinaris
The lentil (''Lens culinaris'' or ''Lens esculenta'') is an edible legume. It is an annual plant known for its lens-shaped seeds. It is about tall, and the seeds grow in pods, usually with two seeds in each. As a food crop, the largest producer is Canada, producing 45% of the world’s total lentils. In cuisines of the Indian subcontinent, where lentils are a staple, split lentils (often with their hulls removed) known as dal are often cooked into a thick curry/gravy that is usually eaten with rice or ''rotis''. Botanical description Name Many different names in different parts of the world are used for the crop lentil. The first use of the word ''lens'' to designate a specific genus was in the 16th century by the botanist Tournefort. The word "lens" for the lentil is of classical Roman/Latin origin: McGee points out that a prominent Roman family took the name " Lentulus", just as the family name "Cicero" was derived from the chickpea, '' Cicer arietinum'', or " F ...

Lathyrus
''Lathyrus'' is a genus of flowering plants in the legume family Fabaceae, and contains approximately 160 species. Commonly known as peavines or vetchlings, they are native to temperate areas, with a breakdown of 52 species in Europe, 30 species in North America, 78 in Asia, 24 in tropical East Africa, and 24 in temperate South America. There are annual and perennial species which may be climbing or bushy. This genus has numerous sections, including ''Orobus'', which was once a separate genus. Uses Many species are cultivated as garden plants. The genus includes the garden sweet pea (''Lathyrus odoratus'') and the perennial everlasting pea (''Lathyrus latifolius''). Flowers on these cultivated species may be rose, red, maroon, pink, white, yellow, purple or blue, and some are bicolored. They are also grown for their fragrance. Cultivated species are susceptible to fungal infections including downy and powdery mildew. Other species are grown for food, including the Indian pea ...

European Nucleotide Archive
The European Nucleotide Archive (ENA) is a repository providing free and unrestricted access to annotated DNA and RNA sequences. It also stores complementary information such as experimental procedures, details of sequence assembly and other metadata related to sequencing projects. The archive is composed of three main databases: the Sequence Read Archive, the Trace Archive and the EMBL Nucleotide Sequence Database (also known as EMBL-bank). The ENA is produced and maintained by the European Bioinformatics Institute and is a member of the International Nucleotide Sequence Database Collaboration (INSDC) along with the DNA Data Bank of Japan and GenBank. The ENA has grown out of the EMBL Data Library which was released in 1982 as the first internationally supported resource for nucleotide sequence data. As of early 2012, the ENA and other INSDC member databases each contained complete genomes of 5,682 organisms and sequence data for almost 700,000. Moreover, the volume of data is ...

Tetrazolium Blue
The formazans are compounds of the general formula -N=N-C(R')=N-NH-R" formally derivatives of formazan 2NN=CHN=NH unknown in free form. Formazan dyes are artificial chromogenic products obtained by reduction of tetrazolium salts by dehydrogenases and reductases. They have a variety of colors from dark blue to deep red to orange, depending on the original tetrazolium salt used as the substrate for the reaction. Structure and reactivity Formazans are intensely colorful compounds characterized by the following structure: N=N-C(R)=N-NH- and are closely related to azo (−N=N−) dyes. Their structure was first defined in 1892, by von Pechmann and by Bamberger and Wheelwright independently. Their deep colour and redox chemistry derive from their nitrogen-rich backbone. Formazans have a high tautomeric and conformational flexibility. Due to the two alternating double bonds in the backbone, formazans can exist in four possible isomeric forms: syn, s-cis (closed form); syn, s ...

Troleandomycin
Troleandomycin (TAO for short) is a macrolide antibiotic. It was sold in Italy (branded Triocetin) and Turkey (branded Tekmisin). It is no longer sold in Italy as of 2018. The drug's mode of action is to bind to the ribosome, specifically in the tunnel through which the newly formed peptide egresses, thereby halting protein synthesis. Troleandomycin is a CYP3A4 inhibitor that may cause drug interaction Drug interactions occur when a drug's mechanism of action is disturbed by the concomitant administration of substances such as foods, beverages, or other drugs. The cause is often the inhibition of the specific receptors available to the drug, ...s.
