GC/MS Analysis of the Extracellular Metabolism of the Endophytic Marine Bacterium CⅢ-1 from Mangrove

Abstract:

The extracellular metabolism products of the marine bacterium CⅢ-1, a endophytic marine bacterium isolated from mangrove (V.C Bruguiera gymnorrhiza), were extracted with dichloromethane and then analyzed by GC/MS technique. The results showed that the mainly chemical composition and their concentrations of the extracellular metabolism of this strain were arachic acid（10.12%）, all-trans-squalene（7.33%），12-tricosanone（7.07%），2-(2-hydroxyethoxy)ethyl stearate（6.21%），tetramethyl-oxirane（4.67%）, pyrrole-2-carboxylicacid-4-(1-chlorodec-1-enyl)-3,5-dimethyl-ethylester(4.63%）, 3-methyl-3-undecene（3.55%） and so on. Among them the all-trans-squalene has an important value of application.
