研究目的
To elucidate the structure of SL components produced by S. bombicola using glucose and palm oil as carbon sources, by MALDI-TOF MS, using HPA as matrix.
研究成果
3-HPA has been found to be the superior matrix for elucidation of structures for SL produced from palm oil by S. bombicola using MALDI-TOF MS. The study identified various SL congeners and demonstrated the utility of comparing negative versus positive ion mode to differentiate between SL of free acid and lactonic forms.
研究不足
The study focused on the structural elucidation of SL using MALDI-TOF MS with HPA as matrix, and did not explore the quantitative aspects of SL production or the optimization of fermentation conditions.
1：Experimental Design and Method Selection:
The study utilized MALDI-TOF MS with HPA as matrix for structural elucidation of SL.
2：Sample Selection and Data Sources:
SL was produced through the cultivation of S. bombicola in growth medium with glucose and palm olein as carbon sources.
3：List of Experimental Equipment and Materials:
MALDI-TOF MS (Voyager Elite XL Biospectrometry Workstation), S. bombicola (ATCC 22214), RBD palm oil, and various chemicals and reagents.
4：Experimental Procedures and Operational Workflow:
SL production, extraction, and MALDI-TOF MS analysis under positive and negative ion modes.
5：Data Analysis Methods:
MALDI-TOF MS spectral analysis for identification of SL components.
