TAILIEUCHUNG - Production and characterization of sophorolipids by candida bombicola using catfish fat

In this work, catfish fat has been used as a sustainable and economical raw material for sophorolipids production by Candida bombicola. Sophorolipids yield was maximum as after 7 days of fermentation at 25oC, pH 6, 180 rpm. | TRƯỜNG ĐẠI HỌC SƯ PHẠM TP HỒ CHÍ MINH TẠP CHÍ KHOA HỌC HO CHI MINH CITY UNIVERSITY OF EDUCATION JOURNAL OF SCIENCE KHOA HỌC TỰ NHIÊN VÀ CÔNG NGHỆ NATURAL SCIENCES AND TECHNOLOGY ISSN: 1859-3100 Tập 14, Số 9 (2017): 152-159 Vol. 14, No. 9 (2017): 152-159 Email: tapchikhoahoc@; Website: PRODUCTION AND CHARACTERIZATION OF SOPHOROLIPIDS BY Candida bombicola USING CATFISH FAT Nguyen Luong Hieu Hoa1, Le Quynh Loan2, Vo Thanh Sang1, Le Van Minh2, Le Viet Dung2, Phung Thi Thu Huong1, Pham Van Duong4, Nguyen Hoang Dung1,3,* 1 NTT Hi-Tech Institute - Nguyen Tat Thanh University 2 Research Center of Ginseng and Materia Medica 3 Institute of Tropical Biology - VAST 4 Vietnam National University HCMC- University of Science Received: 23/8/2017; Revised: 31/8/2017; Accepted: 23/9/2017 ABSTRACT Catfish fat is a high nutrition by-product of seafood processing industry. In this work, catfish fat has been used as a sustainable and economical raw material for sophorolipids production by Candida bombicola. Sophorolipids yield was maximum as after 7 days of fermentation at 25oC, pH 6, 180 rpm. The obtained sophorolipids was to contained the main component as lactonic sophorolipids, which has been confirmed by Thin layer chromatography (TLC). Sophorolipids also exhibited the ability to resistant Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and showed the ability of free radical scavenging the dose dependent manner with IC50 was mg/ml. These results suggested that sophorolipids could be used in health care products and cosmetic. Catfish fat could be used as the low cost hydrophobic carbon source to replace fatty acid for sophorolipids production.
