PE-MP carbon transform in microbial food chain. (A) Schematic view of experiment II, where PE-MP in humic-lake and clear-lake water (summer) was introduced to mixotrophic algae (Cryptomonas sp.) and herbivorous zooplankton (Daphnia magna). External arrow describes transformation of PE-MP carbon first into saturated and monounsaturated fatty acids and finally into essential ω-6 and ω-3 PUFA. The number of replicates in each stage are presented as n. (B) Non-metric multidimensional scaling plots of Bray Curtis similarity of isotopic difference (Δ, treatment-control; ‰) of PLFAs of microbiome (summer and fall), mixtrophic algae (Cryptomonas sp.) and herbivorous zooplankton (Daphnia magna).
