What's the difference between antizymic and fermentation?
Antizymic
Definition:
(a.) Preventing fermentation.
Example Sentences:
(1) These results are consistent with the previous observation in HTC cells that the decay rate of ODC activity in the presence of cycloheximide correlated well with the proportion of ODC present as a complex with antizyme, suggesting the ubiquitous role of antizyme in ODC degradation.

(10) USA 72, 1858-1862]; specifically the inhibitor was nondialyzable, heat labile, and ribonuclease insensitive, and the inhibition was time independent, proportional to the concentration of antizyme present, and noncompetitive with respect to the substrate, ornithine.
(11) The equilibrium constant (binding constant) of the reaction between ornithine decarboxylase and antizyme was a little increased by decreasing salt concentrations in the medium and by decreasing the temperature of incubation.
(12) In this study, we investigated the direct effect of antizyme on ODC decay in hepatoma tissue culture (HTC) cells.
(13) Antizyme was also present as a complex with ODC in the kidney of untreated mouse.
(14) It has additional characteristics similar to those of the ODC antizyme of eukaryote cells: it is a noncompetitive inhibitor of ODC; the complex formed between ODC and the ODC inhibitor can be dissociated with salt to provide active ODC and active ODC inhibitor; furthermore, this E. coli ODC inhibitor is inhibitory to eukaryote ODC.
(15) Rapid, polyamine-induced degradation of mammalian ornithine decarboxylase (L-ornithine carboxy-lyase, EC 4.1.1.17) (ODC) is though to be controlled by the availability of a small, ODC-binding protein termed antizyme.
(16) Wth the use of HMOA cells, a recently cloned rat hepatoma cell line that has a greatly stabilized ODC, it has been possible to demonstrate that 10(-5) M of exogenous putrescine blocks the increase in ODC activity, but unlike in the parent HTC cell line, without induction of the antizyme or formation of any inactive ODC-antizyme complex.
(17) A macromolecular inhibitor to ornithine decarboxylase (ODC) present in mouse brain was identified as ODC antizyme [Fong, Heller & Canellakis (1976) Biochim.
(18) The amount of the renal ODC-antizyme complex was 3-fold higher in male mice than in female mice.
(19) ODC-antizyme complex was present in the extracts of hepatoma tissue-culture (HTC) cells and of ODC-stabilized variant HMOA cells, in much larger amounts in the latter.
(20) Yet, the E. coli antizyme and the rat liver antizyme cross react and inhibit each other's biosynthetic decarboxylases.
Fermentation
Definition:
(n.) The process of undergoing an effervescent change, as by the action of yeast; in a wider sense (Physiol. Chem.), the transformation of an organic substance into new compounds by the action of a ferment, either formed or unorganized. It differs in kind according to the nature of the ferment which causes it.
(n.) A state of agitation or excitement, as of the intellect or the feelings.
Example Sentences:
(1) Thirty-two strains of pectin-fermenting rumen bacteria were isolated from bovine rumen contents in a rumen fluid medium which contained pectin as the only added energy source.
(2) We investigated the possible contribution made by oropharyngeal microfloral fermentation of ingested carbohydrate to the generation of the early, transient exhaled breath hydrogen rise seen after carbohydrate ingestion.
(3) The cell fermentation culture with a stabilized pH value was better than the culture with the pH value changing spontaneously on saponin content, growth rate and biomass.
(4) Forty-five enteropathogenic (enteropathogenic Escherichia coli-like) strains isolated in commercial rabbit farms were subdivided into four biotypes with the help of six carbohydrate fermentation tests, ornithine decarboxylase tests, and motility tests.
(5) The different hydrolytic, fermentative and methanogenic activities of these populations ensure the efficient degradation of cell wall constituent in forages (cellulose, hemicellulose, pectin) ingested by ruminants.
(6) The addition of sodium bicarbonate to gum containing sorbitol markedly enhanced its capacity to cause and maintain an elevation of interproximal plaque pH previously lowered by exposure to fermentable carbohydrate.
(7) The test organisms included 218 gram-negative fermentative clinical isolates.
(8) An investigation was done on the action in vitro of two pharmaceutical preparations containing Bi, De Nol and Pepto Bismol, on the fermentative capacity of intestinal bacteria.
(9) Acid production by carbohydrate fermentation increases urease production by Klebsiella: pH 4 is the most convenient pH for urease synthesis by these bacteria.
(10) These percentages suggest that a better fermentation took place in those silages containing forages.
(11) These swine were compared to four groups fed the medicated diet to determine the effect of duration of treatment and degree of animal isolation on the persistence of resistance in lactose-fermenting enteric organisms.
(12) These cocultures can be considered as metabolic associations, where the Bacillus produces degradation and fermentation products of pectin, which can be used by Azospirillum species.
(13) To show the decisive role of the inoculum parameters in regulation of the specificity of the secondary synthesis, the dynamics of accumulation of certain metabolites forming from glucose along with the main antibiotic and the activity of the key enzymes of the carbohydrate metabolism during the culture growth in the fermentation media were studied.
(14) When fermented in preferential media it produces geldanamycin, nigericin, nocardamine, and a libanamycin-like activity.
(15) Aerobic growth of even the latter strain was largely fermentative (ca.
