Srb

SRB is an acronym that can refer to several terms in science, engineering, and regulation. Among the most widely used meanings are Solid Rocket Booster, Sulfate-Reducing Bacteria, and the Single Resolution Board.

Solid Rocket Booster describes a type of rocket motor in which the propellant is in a solid form. SRBs provide large thrust during launch and are used as part of larger launch systems; notable examples include the pair of boosters used on the Space Shuttle program. After ignition, they burn for a short period, detach, and fall away. Older shuttle boosters were recovered from the ocean, refurbished, and reused; newer systems may be expendable.

Sulfate-Reducing Bacteria refers to a diverse group of anaerobic microorganisms that generate energy by reducing sulfate to sulfide during metabolism. They are commonly found in anaerobic environments such as marine sediments, oil reservoirs, and pipelines. They can contribute to corrosion and souring in oil production and water systems, and are studied in bioremediation and microbiology.

Single Resolution Board is an EU body created to coordinate the resolution of banks that fail within the Banking Union. It works with national resolution authorities and the European Central Bank to prepare and implement resolution plans, including tools like bail-in. The SRB is based in Brussels and operates under the Single Resolution Mechanism.

Because the acronym spans multiple domains, context is essential to determine the intended meaning.
