“…These compounds are transformed into a variety of derivatives through chemical and biocatalytic processes. V. A. Raldugin et al [15] performed chemical oxidation of cembranoids using Jones reagent (aqueous solution of sulfuric acid) and acetone containing CrO 3 . The major products obtained after chemical oxidation were norsiberian-2,7,11-triene-4-one, norsolandione, (3E,8E)-5-isopropyl-8methyldecane (C)-3,8-diene-2,12-dione.…”

Cembranoids compounds are mainly distributed in higher plants of the Pinaceae and Solanaceae families, as well as soft corals, and serve as important aroma precursors. Their degradation products are widely used in various aspects of life, such as farnesal, which finds extensive applications in the pharmaceutical industry. In this study, a strain (Stenotrophomonas maltophilia H3-1) was isolated from soil, which can efficiently degrade α-cedriene-4,6-diol.Based on GC-MS detection of α-cembratriene-4,6-diol degradation efficiency of the H3-1 strain, it was determined that the optimal culture conditions for H3-1 are 40°C, pH 8, maltose concentration of 2 g/L, and ammonium sulfate concentration of 2 g/L. Under the optimum culture conditions, the degradation rate of 1 mg/mL α-cembratriene-4,6-diol by H3-1 strain within 36 h was as high as 85.86%. This indicates the strong biodegradation ability of the H3-1 strain towards α-cembratriene-4,6-diol. Through GC-MS analysis, we identified the biodegradation products of α-cembratriene-4,6-diol, including farnesal. This provides a theoretical basis and microbial resources for further study on the degradation products and applications of α-cembratriene-4,6-diol.
