BACILLUS SPOROTHERMODURANS Meaning and
Definition
-
Bacillus sporothermodurans is a species of bacteria belonging to the genus Bacillus, within the phylum Firmicutes. It is characterized as a Gram-positive, spore-forming, rod-shaped bacterium that can survive under extreme conditions of heat and desiccation. The name "sporothermodurans" is derived from the bacteria's ability to withstand high temperatures (thermodurans) and produce endospores (sporother).
This bacterium is known for its exceptional heat resistance, tolerance to thermal processing, and ability to form highly resilient spores. It can survive thermal treatments used in food and beverage processing, such as pasteurization and sterilization. This resistance is attributed to the inherent thermal stability of its spores and the presence of unique cellular components that protect it from temperature-induced damage.
Bacillus sporothermodurans is typically found in raw and processed milk and dairy products, soil, and other environments. It is considered to be an environmental contaminant in the dairy industry, where it can survive pasteurization and cause spoilage issues in dairy products. Although not generally considered pathogenic, it is important in the food industry due to its ability to survive and grow under conditions that would usually destroy other bacteria.
Studies have been conducted to explore methods to control or eliminate Bacillus sporothermodurans from food processing environments. These include optimizing thermal processing conditions, implementing proper cleaning and sanitation practices, and employing bacteriocidal agents to reduce its presence.
Etymology of BACILLUS SPOROTHERMODURANS
The word "bacillus sporothermodurans" has a scientific etymology. Let's break it down:
1. Bacillus: This term comes from Latin and means "small rod". It was initially used to describe rod-shaped bacteria.
2. Sporo-: This prefix refers to spores, which are the reproductive structures of certain microorganisms. It derives from the Greek word "spora", meaning "seed" or "sowing".
3. Therm-: This prefix relates to heat or temperature and derives from the Greek word "thermos", meaning "hot" or "warm".
4. Durans: This term comes from Latin and means "enduring" or "withstanding". It is the present participle form of the verb "durare", which translates to "to last".
