The selective enrichment of microbial metabolic characteristics of the desired

摘要

A concentration method for enzymes involved in the metabolism of the test substrate and / or selective enrichment of microorganisms that can metabolize the test substrate, the following steps: providing in a container a) microbial population, is initiated by b) an initial flow rate feed the solution into the vessel at a controlled flow rate, nutrient medium, and the solution, d includes a test substrate with at least a portion of the feed period, and provides a signal indicating the metabolic levels over the time frame of the c) concentration relates to a method for including as to provide an output based on a signal that can be evaluated for concentration of the enzymes produced by the microorganisms involved in the metabolism of the test substrate and / or selective enrichment of microorganisms to metabolize) test substrate. In order to facilitate the concentration process, when the steady state is detected, the condition can be set so as to increase the flow velocity in that period. When the condition, and preset conditions to suit the signal output to result in a change in fluid flow rate is appropriate, this may be achieved by varying the flow rate fed into the vessel solution. Conditions where previously set ranges of values ​​and a preset predetermined period, the period signals a predetermined within that range must remain.
