GAS CHROMATOGRAPHY-MASS SPECTROMETRIC ANA- LYSES OF HYDROCARBONS PRODUCED BY DIFFERENT STRAINS OF BOTRYOCOCCUS BRAUNII
几株丛粒藻烃类的气相色谱—质谱分析

The hydrocarbon components produced by three strains of Botryococcus braunii Kutzig were qualitatively identified by gas chromatography-mass spectrometric analyses. Strain A( USA) and B( Germany) produced the same hydrocarbons, chiefly CnH2n-2 and CnH2n-4 liner alkenyl hydrocarbons. The strain C from Fuxian lake, Yunnan province, China, produced mainly botryococcenes and iso-botryococcenes, highly branched and unsaturated hydrocarbons. The reason of production of different hydrocarbon types by different strains of Botryococcus braunii Kutzig was discussed.
