Loktanella Koreensis

Description and significance

Members of the genus Loktanella have been isolated from microbial mats and marine environments¹, which is why the genus was named after Tjhing-Lok Tan from the Alfred Wegener Institute in Bremerhaven because of his contribution to the understanding of marine and polar bacteriology and ecology. Bacteria in this genus are Gram-negative bacilli (rod-shaped cells) that metabolize by strictly aerobic means and are chemoheterotrophic (gain energy from organic chemical compounds). Loktanella are moderately halotolerant (adapted to conditions of high salinity), do not produce spores, are not observed to be motile, and grow at an optimum temperature of 25^oC.²

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Genome structure

93.5–96.1 %; highest sequence similarity was with Loktanella rosea. The G+C content of the genomic DNA of strain GA2-M3T was 60.0 mol% and the predominant ubiquinone was Q-10. Major fatty acids were 18 : 1ω7c, 18 : 0 and 18 : 1ω7c 11-methyl.³

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?

Cell structure and metabolism

The bacteria within the genus Loktanella are strictly aerobic, chemoheterotrophs. Interesting features of cell structure; how it gains energy; what important molecules it produces.

Ecology

Habitat; symbiosis; contributions to the environment.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
