Sophorolipids Production by Candida bombicola ATCC 22214 and its Potential Application in Microbial Enhanced Oil Recovery
Biosurfactant production using Candida bombicola ATCC 22214, its characterization and potential applications in enhancing oil recovery were studied at laboratory scale. The seed media and the production media were standardized for optimal growth and biosurfactant production. The production media were tested with different carbon sources: glucose (2%w/v) and corn oil (10%v/v) added separately or...
متن کاملThe effect of medium composition on the structure and physical state of sophorolipids produced by Candida bombicola ATCC 22214.
Candida bombicola was grown using a variety of lipophilic carbon substrates. Most of the hydrocarbon and carboxylic acid substrates resulted in a mixture of sophorolipids consisting of free acids and the more desirable lactones. The ratio of diacylated lactone to free acid in these mixtures was a maximum when produced using hexadecane and heptadecane. All of the other lipophilic substrates resu...
متن کاملSophorolipids Production by Candida Bombicola using Synthetic Dairy Wastewater
Sophorolipids (SLs) production by the yeast Candida bombicola was studied in batch shake flasks using synthetic dairy wastewaters (SDWW) with or without any added external carbon and nitrogen sources. A maximum SLs production of 38.76 g/l was observed with the SDWW supplemented with low cost substrate of sugarcane molasses at 50 g/l and soybean oil at 50 g/l. When the SDWW was supplemented with...
متن کاملPRODUCTION OF SOPHOROLIPIDS USING THE YEAST Candida bombicola ATTC 22214 FOR THE APPLICATIONS IN THE FOOD INDUSTRY
Lactonic sophorolipids were produced by the yeast Candida Bombicola ATTC 22214 (Torulopsis bombicola) in a 3L bioreactor using batch cultivation, with corn oil and glucose as carbon sources. The main compound of the lactonic mixture was separated from the mixture by column chromotography and was identified as 17 hydroxyoctadecanoic-1’,4’’-lactone 6’ 6’’ diacetate sophorolipid. Surface tension m...
متن کاملMicrobial Enhanced Oil Recovery Using Biosurfactant Produced by Alcaligenes faecalis
A bacterial strain (designated as Alcaligenes sp. MS-103) isolated from oil sample of the Aghajari oilfield in the south of Iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. The highest surface tension reduction to level 20 mN/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...
