endospore-forming bacteria

Thân thiện

A scientist observes endospore-forming bacteria under a microscope.

Definition

Noun: A group of true bacteria characterized by their ability to produce endospores. Endospores are highly durable, dormant structures formed within the bacterial cell to survive extreme environmental conditions such as heat, radiation, and chemical disinfectants.

Usage

The term "endospore-forming bacteria" is used in microbiology to classify and describe a specific physiological group of bacteria based on this key survival mechanism. It is a scientific and taxonomic descriptor.

Examples

• and are the two primary genera of endospore-forming bacteria.
• The presence of endospore-forming bacteria in canned food can pose a serious health risk if the sterilization process fails.
• Researchers studied the resistance of endospore-forming bacteria to ultraviolet light.

Advanced Usage

• The term is often used in contrast to bacteria that do not form endospores, highlighting a critical difference in survival strategy.
• In medical contexts, it underscores the challenge of sterilizing equipment and environments, as endospore-forming bacteria can withstand standard autoclaving if not properly performed.

Variants and Related Words

• Endospore (n): The resistant dormant structure itself.
• Sporulation (n): The process of forming an endospore.
• Bacillus (n): A genus of rod-shaped, endospore-forming, aerobic bacteria.
• Clostridium (n): A genus of rod-shaped, endospore-forming, anaerobic bacteria.

Synonyms

• Spore-forming bacteria (This is a direct synonym, though "endospore-forming" is more precise in bacteriology).

Notes on Meaning

This term refers specifically to a group or category of bacteria, not to the act of spore formation. The defining characteristic is their capability to form endospores, which is a taxonomic and descriptive feature.
