Impact of temperature on ladderane lipid distribution in anammox bacteria.

ABSTRACT: Anaerobic ammonium-oxidizing (anammox) bacteria have the unique ability to synthesize fatty acids containing linearly concatenated cyclobutane rings, termed "ladderane lipids." In this study we investigated the effect of temperature on the ladderane lipid composition and distribution in anammox enrichment cultures, marine particulate organic matter, and surface sediments. Under controlled laboratory conditions we observed an increase in the amount of C(20) [5]-ladderane fatty acids compared with the amount of C(18) [5]-ladderane fatty acids with increasing temperature and also an increase in the amount of C(18) [5]-ladderane fatty acids compared with the amount of C(20) [5]-ladderane fatty acids with decreasing temperature. Combining these data with results from the natural environment sho
