Phospholipid fatty add

Phospholipid fatty add assays can also indicate metabolic changes in a microbial community. During nutrient deprivation and other environmental stresses, fatty add ratios can shift. Guckert et al. [36] found increases in the transxis ratio of monoenoic 16-carbon tty adds in Vibrio cholerae during nutrient starvation. The protocol used to extract the lipids fix>m environmental samples simultaneously extracts other biochemical indicators of nutritional status in microbial communities, for example, poly-P-hydroxyalkanoates [31].
