Taxonomy
Description
Morphological Characteristics
Zobellia laminariae are gram-negative agarolytic bacteria with gliding motility that produce flexirubin-type pigments. Cells range in size from 0.4 to 0.5 mm in width and from 1.2 to 1.4 mm in length.
Genetic Characteristics
The G+C content of the DNA is 36-37 mol% and it has a DNA-DNA binding value of 93%. Zobellia laminariae is closely related to Zobellia amurskyensis and Zobellia russellii.
Environmental Characteristics
The bacteria prefer marine salinity and their living in sea water on brown algae called Laminaria japonica. Optimum growth occurs between 21-23°C but they can grow any where between the range of 4-30°C. They prefer a salt concentration between 1.5-6% NaCl with an optimum at 2%.
Host
Metabolism
They are heterotrophic meaning they require complex organic compounds of nitrogen and carbon for metabolic synthesis. They utilize L-arabinose, D-glucose, D-lactose, D-mannose, D-sucrose, and mannitol. They hydrolyze agar, gelatin, and Tween 40. The whole cell fatty acid composition is 15 : 0, i15 : 0, i15 : 0 3-OH, i15 : 1, i17 : 0 3-OH. MK-6 is the major lipoquinone.
Metabolite Products
Produces acid from the fermentation of L-arabinose,D-cellobiose, D-glucose, L-fucose, D-maltose, D-raffinose, L-rhamnose, D-sucrose and mannitol.
Antibiotic Caracteristics
Zobellia laminariae are sensitive to carbenicillin, lincomycin and oleandomycin antibiotics. They are resistant to ampicillin, benzylpenicillin, gentamicin,kanamycin, neomycin, polymyxin B, streptomycin and tetracycline.
Current Research
describe one or two topics of research on this microbe
