Temperature-Induced Changes in the Membrane Fluidity of Zymomonas Mobilis: Study Using a New Flourescent Probe, ABM

The use of a newly synthesized fluorescent probe, ABM (conditional name), to determine changes of membrane composition (fluidity), biomass yield, ethanol productivity, and yield of Zymomonas mobilisunder anaerobic conditions was investigated. A strong correlation between ABM spectral characteristics in cell suspension and all obtained parameters was observed. It was concluded that application of ABM is a useful tool to detect temperature-induced changes in the membrane composition of Zymomonas mobilis.
