Description

Materials possessing earthy-musty odor produced by blue-green algae were isolated from water samples from river, pond, moat and lake around Tokyo. Each of blue-green algae was cultured in a modified Fitzgerald liquid medium at 25°C under 1000 lux for one to seven weeks. Volatile metabolites produced by these algae were identified by means of GC-MS. 2-Methylisoborneol was produced by Oscillatoria geminata and geosmin by Oscillatoria amoena, Oscollatoria splendida and Aphanizomenon sp. The result suggested that Streptomyces generally produced both odorous compounds while blue-green algae produced either 2-methylisoborneol or geosmin. n-Heptadecane was also detected in the culture mediumn of all blue-green algae. Other volatile metabolites identified were as follows ; n-pentadecane, 1-heptadecene, 7-methylheptadecane, germacrene-D, γ-cadenene, sesquiterpene alcohol and phytol.
