Abstract: Objective: To explore the optimum synthetic medium suitable for β-carotene-degrading Staphylococcus sp.. Methods: The medium composition was determined and essential nutrients for β-carotene-degrading Staphylococcus sp. were chosen by single component deficiency method. Results: K2HPO4, NaNO3, proline, arginine, valine, glycine and tryptophan were essential for the growth of β-carotene-degrading Staphylococcus sp.. Conclusion: The optimized synthetic medium is suitable for the cultivation of β-carotene-degrading Staphylococcus sp. to produce β-carotene-degrading materials.

Key words: essential nutrients, single component deficiency, synthetic medium, β-carotene degradation
