FIG 2.

Influence of Lo18 and ethanol growth on the fluidity of liposomes derived from O. oeni. Liposome fluidity is expressed in anisotropy R values as a function of temperature in the absence (filled circles) or presence (open circles) of 10 μM Lo18. Liposomes were prepared from membrane lipids extracted from O. oeni grown under optimal growth conditions (A) or grown in 8% ethanol (B). The mass ratio between protein and liposomes was 1:2. The experiments were done in triplicate; vertical bars indicate standard deviations. Asterisks show statistically significant differences (P < 0.05).
