Fatty acid methyl acid (FAME) composition of Fremyella diplosiphon wild type (Fd33) and halotolerant (HSF33–2) transesterified lipids grown in the absence of gold nanoparticles (AuNPs) and in solution with 200 nm AuNPs. Treatments are denoted as follows: Fd33 in the absence of AuNPs (WC) and in solution with 200 nm AuNPs (W200); HSF33–2 in the absence of NP (HC) and in solution with 200 nm AuNPs (H200). Bars represent average % relative content of FAME component (± standard error) for three biological replicates. Different letters above bars denote significance among treatment means within each strain (p < 0.05).
