How do Spirilla get energy?
These strict anaerobes obtain their energy by dissimilatory sulfate reduction or “respiratory sulfate reduction” in which sulfate acts as a terminal electron acceptance (instead of oxygen in the aerobic forms of life) for the respiratory process.
Is spirillum bacteria aerobic or anaerobic?
All known members are obligate anaerobes, capable of both photoheterotrophic growth in the light and chemoheterotrophic growth in the dark.
Is spirillum autotrophic or heterotrophic?

How do spirillum bacteria move?
Spirillum (plural, spirilla). A bacterium with rigid spiral (helical) structure (not easily band, not flexible), thick, long, and move with flagella, 6–15 μm long and spiral in shape is called spirillum.
What type of bacteria is spiral shaped?
spirochete, (order Spirochaetales), also spelled spirochaete, any of a group of spiral-shaped bacteria, some of which are serious pathogens for humans, causing diseases such as syphilis, yaws, Lyme disease, and relapsing fever. Examples of genera of spirochetes include Spirochaeta, Treponema, Borrelia, and Leptospira.

Is Spirillum motile?
Spirillum is microbiologically characterized as a gram-negative, motile helical cell with tufts of whiplike flagella at each end.
Is Spirilla prokaryotic or eukaryotic?
Prokaryotic cells come in multiple shapes: cocci (round), baccilli (rods), and spirilla or spirochetes (helical cells).
