Background: The choice of an appropriate type of orthosis depends on the patient's specific condition and needs. Different types of orthoses can affect plantar pressure distribution during certain gait patterns. Toe and heel gaits are common patterns of gait assigned for optimal recovery in patients with foot or ankle injuries.

Article Synopsis
  • A new marine bacterium called MEBiC08158(T) was isolated from sediments near an oil spill in Korea and is closely related to Alcanivorax marinus but distinct enough to be classified as a new species.
  • The bacterium can grow in a wide range of temperatures (15-43 °C), pH levels (6.0-9.5), and salt concentrations (0.5-16% NaCl), with optimal conditions around 37-40 °C, pH 7.0-8.0, and 1.5-3.0% NaCl.
  • Unique fatty acid profiles and various phenotypic characteristics support the classification of MEBiC08158(T)

A bacterial strain (B2-7(T)) capable of degrading a wide range of polycyclic aromatic hydrocarbon compounds (2-4 rings) was isolated from a water sample taken from Botan Oil Port in Xiamen, China. The isolate was Gram-negative, short-rod-shaped, aerobic, non-motile and formed yellow-pigmented colonies on LB medium. Cells of strain B2-7(T) were catalase-positive and oxidase-negative.
