Horizontal flow traps of various designs have been used to collect bacteria from air, water and surfaces. In this study, we developed a device that would enable evaluation of the traps with regard to their efficiency in trapping bacteria and the behavior of bacteria during transit in the traps. The device was constructed so that it could be placed directly in air or water and tested in the laboratory for several hours. The bacterial load collected was determined by plating the samples on agar plates and counting the number of colonies. The results from both indoor and outdoor experiments show that the traps successfully collect large numbers of bacteria and in principle they can be used for long periods. The rate of growth of bacteria in the traps was also studied. Bacteria trapped in the traps could not be transferred from the traps to a fresh medium, but some were able to survive the transit in the traps. This indicates that some bacteria survived the transit and were released in the fresh medium, even though the traps were prefilled with sterile medium. However, the numbers of bacteria in the fresh medium were so low that they could not be detected by counting colonies.Q:
Was ist der Unterschied zwischen „übermäßig“ und „zu sehr“?
Im Beispielsatz habe ich diese Frage gestellt:
Meine Kinder haben übermäßig gegessen.
oder
Meine Kinder haben zu sehr gegessen.
Was ist der Unterschied zwischen den beiden Sätzen? Was ist der Unterschied zwischen dem Substantiv übermäßig und dem Substantiv sehr? Gibt es einen Unterschied zwischen den beiden Sätzen?

Nicht in Formulierungen wie
