Applications and advances in using phospholipid fatty acids (PLFAs) as biomarkers in analyzing soil microbial communities
摘要
Microbial communities are an integral part of healthy soil ecosystems and plant production, and microbial community function and structure are responsive to a myriad of environmental factors and management practices. The cell membranes of bacteria and fungi contain phospholipids as a key component, and when extracted from soil and analyzed, they provide a snapshot of the microbial community structure in that particular soil environment. Microbial ecologists have extensively used phospholipid fatty acid (PLFA) analysis for more than 40 years in environmental studies. This biomarker-based method is a robust tool for understanding microbial dynamics and soil health, and its versatility across a range of ecosystems has been well established.
