Tenacibaculum ovolyticum

Tenacibaculum ovolyticum is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tenacibaculum ovolyticum rather than just read about it. In short: Tenacibaculum ovolyticum is a species of marine, gram-negative bacteria. The species is best known as an opportunistic pathogen of Atlantic halibut (Hippoglossus hippoglossus) eggs and larvae, where it can contribute to egg mortality be degrading the egg envelope.

Reference excerpt

Tenacibaculum ovolyticum is a species of marine, gram-negative bacteria. The species is best known as an opportunistic pathogen of Atlantic halibut (Hippoglossus hippoglossus) eggs and larvae, where it can contribute to egg mortality be degrading the egg envelope.

Taxonomy The species was originally described as Flexibacter ovolyticus after its isolation from halibut eggs in Norway. It was later transferred to the genus Tenacibaculum following phylogenic studies demonstrating that it was only distantly related to the type species of Flexibacter and instead formed a distinct lineage with several marine flavobacteria, including Tenacibaculum maritimum.

Phenotypic characteristics

Morphology Tenacibaculum ovolyticum is a gram-negative, rod-shaped bacterium. Cells are typically 2-20 μm long and approximately 0.5 μm wide. The bacterium demonstrates gliding motility, a characteristic shared with several other members of the genus Tenacibaculum. This species tolerates pH between 5.9 and 9.0.

Growth characteristics T. ovolyticum is adapted to cold marine environments and grows at temperatures between approximately 4 and 25 °C. Growth is dependent on seawater and does not occur in media supplemented with sodium chloride alone, distinguishing it from many related species that tolerate a wider range of salinities. T. ovolyticum produces both catalase and oxidase. The species does not reduce nitrate under normal laboratory conditions.

Aquaculture relevance Tenacibaculum ovolyticum has been isolated from several species of fish including Atlantic halibut, sardine (Sardina pilchardus) eggs, and American lobster (Homarus americanus).

Disease in halibut hatcheries Tenacibaculum ovolyticum was originally identified during investigations of disease outbreaks affecting Atlantic halibut eggs and larvae in marine hatcheries. Experimental studies demonstrated that the bacterium could colonize egg surfaces and contribute to mortality during embryonic development and early larval stages.

Ecology Tenacibaculum ovolyticum is a marine bacterium that has been recovered from fish eggs and other seawater-associated environments. The species is adapted to cold marine conditions and requires seawater-derived ions for growth. Its ability to degrade biological polymers such as casein, DNA, and chitin suggests a role in the turnover of organic material in marine ecosystems.

Worked examples

Example 1 — a first encounter with Tenacibaculum ovolyticum

Start with the simplest possible case. Write down what Tenacibaculum ovolyticum claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tenacibaculum ovolyticum before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tenacibaculum ovolyticum ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tenacibaculum ovolyticum

In research: Tenacibaculum ovolyticum appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tenacibaculum ovolyticum in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tenacibaculum ovolyticum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 1992, Flavobacteria, Gram-negative bacteria, so understanding it makes those chapters shorter.
In everyday life: Look for Tenacibaculum ovolyticum outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
