Description and significance
"Lutibacter maritimus" is an aerobic, gram negative, rod shaped bacteria belonging to the family "Flavobacteriaceae". It is non-motile, non-flagellated, and non-gliding and measures to be 0.3–0.8 µm in diameter and 1.0–5.0 µm in length. Carotenoid pigments are produced. Maltose is used as the sole carbon and energy source. The major fatty acids consist of iso-C15 : 0 and C15 : 1v6c[1]. "L. maritimus" prefer to grow at neutral pH levels of 7.0-8.0, but can grow at a lower pH of 5.0. It also prefers temperatures between 20-30°C, but can grow at temperatures as low as 4°C or as high as 37°C. In addition, growth can occur with a NaCl concentration between 0.5%-5.0% but a 2.0% concentration is preferred.
Environment
"Lutibacter maritimus" was first isolated from a tidal flat sediment from the west coast of Korea. At the time, it’s genus "Lutibacter", comprised of a single known species, "Lutibacter litoralis", which was also first isolated from a tidal flat sediment[2]. Although they are found in similar environments, and share optimum growth ranges for pH, temperature and NaCl concentration, "L. littorals" has smaller growth ranges for each. Growth for "L. littorals" occurs at 5–30°C, at pH values of 7-8 and at salt concentrations of 1–5%[2], while growth for "L. maritimus" occurs at 4-37°C, at pH values of 5-8 and at salt concentrations of 0.5%-5.0%. The pH growth range beginning at a pH of 5 for "L. maritimus" allows for growth in much more acidic conditions than "L. littorals". The temperature range of 4-37°C for "L. maritimus" allows for growth at warmer and slightly colder water temperatures, while the salt concentration range of 0.5%-5.0% allows for growth at a lower salinity level. "L. maritimus’" overall wider growth ranges for pH, temperature and NaCl concentration suggests it is capable of withstanding more diverse environmental conditions and serves as environmental advantages over "L. litoralis".
Antibiotic Characteristics
Differences in antibiotic susceptibility also helped distinguish "Lutibacter maritimus" as a separate strain from "Lutibacter littorals". Susceptibility was tested on MA plates using a variety of antibiotic discs[3]. Results show both strains were susceptible to carbenicillin, chloramphenicol, lincomycin and oleandomycin, however, "L. maritimus" also showed resistance to cephalothin, streptomycin, penicillin G and tetracycline while "L. litoralis" showed susceptibility.
