Bönersibel
bönersibel is a genus of extremophilic bacteria first isolated from high‑altitude hydrothermal vents in the Mariana Trench. The genus was named by Dr. Hans Böners in 2021 after his pioneering work on pressure‑adapted microorganisms. Members of bönersibel are Gram‑negative, rod‑shaped cells that exhibit remarkable tolerance to both high hydrostatic pressure and high ionic strength. Morphological studies using transmission electron microscopy revealed a robust outer membrane rich in phospholipids, which is thought to confer resistance to the crushing forces found at depths exceeding 10,000 meters.
Genomic sequencing of the type strain, Bönersibel thermolyticus, uncovered a suite of genes encoding trehalose‑synthesizing enzymes
Ecological surveys have documented bönersibel in sediment slurries from several oceanic trenches, indicating a broader distribution
