RESPIRATION ACTIVITY IN FLEXIBACTER CHINENSIS UNDER STARVATION STRESS

Abstract

Electron transport system (ETS) activity was found to be related to the initial inoculum size,culturability and viability of E. coli. In this experiment, ETS activity of Flexibacter chinensis was measuredby INT-method under a variety of conditions such as starvation media with different amendments anddifferent temperatures. The relation between ETS activity, cell culturability, and viability was investigated.We found that the addition of glucose increased ETS activity without affecting cell culturability. Ureaaddition led to an increase in survival, but did not increase ETS activity.
