Taxonomy

[NCBI Taxonomy]

Description

Genetic Characteristics

The G+C content of the DNA is 36-37 mol%.

Morphological Characteristics

Cells range from 0.4 to 0.5 mm in width and from 1.2 to 1.4 mm in length. They are gram-negative agarolytic bacteria with gliding motility that produce ﬂexirubin-type pigments.

Environmental Characteristics

The bacteria live in sea water on brown algae called Laminaria japonica. Optimum growth occurs between 21-23°C but 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. The fatty acids are 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.

Include as many headings as are relevant to your microbe (including things like cell metabolism, ecology, pathology, application to biotechnology). Or, if your microbe is very new and not well studied, then include a heading or two with more description about its native environment or something related to its lifestyle.

Current Research
