title: Occurrence of 2- and 3-hydroxy fatty acids in high concentrations in the extractable and bound lipids of Flavobacterium meningosepticum and Flavobacterium IIb.
abstract: The major hydroxy fatty acids of cellular lipids in Flavobacterium meningosepticum and Flavobacterium sp. King's group UUb were identified as 2-hydroxy 13-methyltetradecanoic, 3-hydroxy 13-methyltetradecanoic, 3-hydroxy palmitic, and 3-hydroxy 15-methylhexadecanoic acids using gas chromatography-mass spectrometry and GC-mass fragmentography. The concentration of these hydroxy fatty acids comprised up to 30-40% of the total extractable and 20-30% of the bound lipid fatty acids, respectively. From the stability for mild alkaline hydrolysis, 2-hydroxy fatty acids seemed to be attached with ester linkage, and 3-hydroxy fatty acids with amide linkage.
