1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
(+)-Lariciresinol at its minimum inhibitory concentration caused efflux of potassium ions and release of 260 nm absorbing material from Escherichia coli O157:H7 and Staphylococcus aureus, with deteriorated cell wall morphology on electron microscopy.
Experimental context and source evidence
- duration
- Not stated here
- evidence_access
- Primary PubMed abstract and indexed metadata reviewed. Full-text method details not stated here remain unresolved.
- experimental_model
- Staphylococcus aureus KCTC1621 and Escherichia coli O157:H7
- exposure
- (+)-Lariciresinol at minimum inhibitory concentration; MIC and minimum bactericidal concentration both 125 to 250 µg/mL
- limitations
- The active concentration is roughly 350 to 700 micromolar, two orders of magnitude above the concentrations at which the Nrf2 and enzyme mechanisms operate. Membrane permeabilisation at such concentrations is a low-selectivity mechanism.
