Rhizobium Lentis
''Rhizobium lentis'' is a gram-negative bacteria, gram-negative bacterium which was isolated from root nodules of lentils in Bangladesh. Description ''Rhizobium lentis'' are Bacillus (shape), rod-shaped bacteria found in the soil. They Aerobic organism, require oxygen and do not Sporogenesis, form spores. ''Rhizobium lentis'' grow well on YEMA medium Agar plate, agar, where they form Colony (biology), colonies which are circular, convex and creamy white. These bacteria grow at 12–37 °C but can survive at temperatures as low as 4 °C. Strains grow well at pH 5.5 to 8.2. Most of the strains studied are resistant to ampicillin, kanamycin and nalidixic acid. Strains do not tolerate tetracycline and do not show any growth on LB medium. ''Rhizobium lentis'' can utilize α-D lactose, β-methyl-D-glucoside, D-sorbitol, D-mannito, D-arbitol-glycerol, D-fructose-6-phosphate, L-aspartic acid, D-gluconic acid, mucic acid, D-lactic acid methyl ester, L-lactic acid, L-histidin ...

Gram-negative Bacteria
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 lipopol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
