Millihertz waveband oscillations in an unstirred bacterial culture
Abstract
Recently the oscillatory bioluminescence of an unstirred and exposed-to air-culture of lux-gene modified, copper-sensitive Alcaligenes eutrophus (a bacterium preferring the liquid—gas interface as a habitat) was discovered (Simkus et al. (1999) Biotechnol Tech 13: 529). Here we report the spectral analysis of the bioluminescence oscillations recorded after illumination of the unstirred bacterial culture. The millihetz waveband spectra obtained were close to the spectrum of a frequency continuum or contained well-resolved sharp peaks, which were attributed to a certain resonance phenomenon in the optimized cultures.
