Response Mechanisms of Bacterial Degraders to Environmental Contaminants on the Level of Cell Walls and Cytoplasmic Membrane

Figure 1

Two mechanisms increasing bacterial membrane saturation and decreasing membrane fluidity. The first one (direction from (b) to (a)) describes the increase of the synthesis of saturated fatty acids (green circles) instead of cis unsaturated fatty acids (orange circles); the second one (from (b) to (c)) shows the isomerization of cis unsaturated fatty acids into corresponding trans isomers (purple circles).
