摘要

Systems biology is a "new" field in life sciences. One element of systems biology relates tornthe massive collection of data on all the biochemical processes in a living cell. The expressionrnlevel of all the genes can be measured using DNA chips, a significant part of all proteins canrnbe identified and quantified by proteomic methods, and a large number of the metabolitesrnmeasured using combinations of chromatography and mass spectrometry This analyticalrnexercise is expensive, laborious and certainly not adaptable to routine use. However, from thisrnmassive amount of data a limited number of parameters can be identified which are predictivernfor a certain chain of events. These parameters, I.e. biomarkers, may combine expressionrnpatterns, proteins and metabolites. Robust and affordable tools can be developed to measurernthese specific markers. Early observation of a shift in the physiological state of bothrngerminating barley and of yeast should help to better control the processes in both maltingrnand brewing. However, a significant research input is required to identify relevantrnbiomarkers.
