Besides other effects, plants are during their life endangered also by pathogenic microorganisms. Current information on negative effects of pathogenic microorganisms occurring on a barley caryopsis is incomplete and insufficient. The presence of pathogenic microorganism on cereals can negatively affect not only quality characters of caryopses but it can also complicate following processing. Contact of the pathogenic microorganism with a cell triggers a number of coordinated intracellular processes with the aim to mitigate or fully eliminate its action and spreading. The whole process is connected with creation of new substances (primary and secondary...

Volatile sulphur substances are precursors of sulphur amino acids, first of all sulphur amino acid metionine. Content of methionine was studied in Czech and foreign beers obtained from the retail shops. The technique for the determination of methionine in beer was optimized using the gas chromatography method with a selective flame photometric detector. Following validation parameters were achieved: LOD 0.80 mg.l-1, LOQ 2.5 mg.l-1, R2 0.99974, RSD 13 %.Volatile sulphur substances are precursors of sulphur amino acids, first of all sulphur amino acid metionine.
