Abstract: | 3-Hydroxy acids were detected in pure cultured microalgae: Chlorophyta—Chlamydomonas reinhardtii and Chlorella pyrenoidosa and Rhodophyta—Cyanidium caldarium (two strains), and cyanobacteria (Cyanophyta)—Anacystis nidulans, Phormidium foveolarum, Anabaena variabilis and Oscillatoria sp. Normal and branched (iso and anteiso) 3-hydroxy acids in the ranges of C8-C26 were found in all the samples studied at concentrations ranging from 0.036 to 2.3 and 0.000 to 0.12 mg g?1 of dry sample, respectively. The major constituents were generally even-carbon numbered normal acids with carbon chain lengths below C20. Microalgae and cyanobacteria may be the important sources of 3-hydroxy acids in natural environments. |
