A combined lipidomic and 16S rRNA gene amplicon sequencing approach reveals archaeal sources of intact polar lipids in the stratified Black Sea water column.

PS‐, PG‐, and PE‐archaeol also displayed depth profiles comparable to the three 2PG‐GDGTs in the deep euxinic waters (Table 2 ) and also showed a highly significant correlation ( r > 0.99) with the depth profile of the ANME‐1 reads (Figure 3 ; Supporting Information Table S6 ).
