Beggiatoa alba
Classification
Domain: bacteria; Phylum: Pseudomonadota; Class: Gammaproteobacteria; Order: Thiotrichales; family: Beggiatoaceae
Description and Significance
Description: Strains of colorless, filamentous, gliding bacteria, visible to the naked eye.
Size: Ranging from about 3.0 to 5.0 μm in diameter
Habitat: Lives at the oxic/anoxic interface of aquatic habitats in high concentrations of sulfide reaching toxic levels.
Importance: Due to its ability to detoxify sulfide, this microbe plays a huge role in the sulfur cycle of coastal environments.
Genome Structure
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, Metabolism and Life Cycle
Interesting features of cell structure?: The cell wall consists of five discrete layers external to the cytoplasmic membrane, the surface layer contains linear arranged longitudinal fibrils ranging from 10 to 12 nm in diameter, thin sections of sulfur inclusions contain 12 to 14 nm thick pentalaminar envelope.
metabolism: the metabolism of this species of Beggiatoa is facultative Methylotrophs within a fresh water strain.
