FIG 1.

Fatty acid content of O. oeni whole membrane and liposomes derived from the membrane. The fatty acid content (percentage of the total fatty acids) of O. oeni (A) and of liposomes prepared from lipids extracted from O. oeni membranes (B) is shown. In each panel, white columns correspond to optimal growth conditions and black columns correspond to cultures grown in 8% ethanol. The mean of six GC profiles is presented; vertical bars indicate standard deviations; asterisks show statistically significant differences between the fatty acid content of control and ethanol liposomes (P < 0.05). cyc, cyclic.
