Factors affecting antibacterial activity of hop compounds and their derivatives
Abstract
W.J. SIMPSON AND A.R.W. SMITH. 1992. The antibacterial effect of weak acids derived from the hop plant ( Humulus lupulus L.) increased with decreasing pH. Analysis of the minimum inhibitory concentration of such compounds against Lactobacillus brevis IFO 3960 over pH4–7 suggests that undissociated molecules were mainly responsible for inhibition of bacterial growth. The antibacterial activity of trans ‐isohumulone was ca 20 times greater than that of humulone, 11 times greater than that of colupulone and nine times greater than that of trans ‐humulinic acid when the degree of ionization was taken into account. Monovalent cations (K+, Na+, NH 4 +, Rb+, Li+) stimulated antibacterial activity of trans ‐isohumulone but the effect was smaller than that observed with H+. The response to divalent cations varied: Ca2+ had little effect on antibacterial activity, whereas Mg2+ reduced activit. Lipid materials and β‐cyclodextrin also antagonized the antibacterial action of trans ‐isohumulone.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
