Factorial Design to Optimize Biosurfactant Production by Yarrowia lipolytica
In order to improve biosurfactant production by Yarrowia lipolytica IMUFRJ 50682, a factorial design was carried out. A 2(4) full factorial design was used to investigate the effects of nitrogen sources (urea, ammonium sulfate, yeast extract, and peptone) on maximum variation of surface tension (Delta ST) and emulsification index (EI). The best results (67.7% of EI and 20.9 mN m(-1) of Delta ST...
متن کاملA Factorial Design To Optimize Cell-Based Drug Discovery Analysis
Drug discovery is dependent on finding a very small number of biologically active or potent compounds among millions of compounds stored in chemical collections. Quantitative structure-activity relationships suggest that potency of a compound is highly related to that compound's chemical makeup or structure. To improve the efficiency of cell-based analysis methods for high throughput screening,...
متن کاملStatistical approach to optimize production of biosurfactant by Pseudomonas aeruginosa 2297
The main objective of this paper is to optimize biosurfactant production by Pseudomonas aeruginosa 2297 with statistical approaches. Biosurfactant production from P. aeruginosa 2297 was carried out with different carbon sources, and maximum yield was achieved with sawdust followed by groundnut husk and glycerol. The produced biosurfactant has showed active emulsification and surface-active prop...
متن کاملUsing a vector pool containing variable-strength promoters to optimize protein production in Yarrowia lipolytica
BACKGROUND The yeast Yarrowia lipolytica is an increasingly common biofactory. To enhance protein expression, several promoters have been developed, including the constitutive TEF promoter, the inducible POX2 promotor, and the hybrid hp4d promoter. Recently, new hp4d-inspired promoters have been created that couple various numbers of UAS1 tandem elements with the minimal LEU2 promoter or the TE...
متن کاملDisruption of Yarrowia lipolytica biofilms by rhamnolipid biosurfactant
BACKGROUND Yarrowia lipolytica is an ascomycetous dimorphic fungus that exhibits biofilm mode of growth. Earlier work has shown that biosurfactants such as rhamnolipids are efficient dispersants of bacterial biofilms. However, their effectiveness against fungal biofilms (particularly Y. lipolytica) has not been investigated. The aim of this study was to determine the effect of rhamnolipid on a ...
