文摘
- •
Ornithine lipids in two bacterial extracts of R. sphaeroides were investigated.
- •
RPLC-ESI with multistage mass spectrometry was applied.
- •
Several combinations of ester- and amide-linked fatty acids were ascertained.
- •
An unusual OL 3-OH 18:0/19:2 was retrieved only in the strain R26.
