Determination of phospholipid fatty acids in sediments

Popis výsledku v původním jazyce

Fatty acid patterns of phospholipids were determined in different environmental samples using phospholipid fatty acids (PLFA) analysis in order to characterize their microbial community structures. Hyporheic gravel-sand sediment samples were collected from Sitka Stream, muddy sediment samples from several weirs on the Morava River, activated and digested sludge from Olomouc water purification plant and sand samples from filters in Olomouc water treatment plant. Profiles of PLFA indicate clear diff erences between these types of samples. The muddy sediments showed high percentages of ester-linked polyunsaturated fatty acids contributed by river phytoplankton. The longer chain fatty acids (26#30 C), indicators for organic matter of allochthonous origin,are increased in the hyporheic sediments. Activated and digested sludge contain much poorer profiles than other samples, probably because of the lower occurrence of bacteria.
