Effects of Medium Components on Isocitric Acid Production by Yarrowia lipolytica Yeast

Fermentation Conditions and Media Optimization for Isocitric Acid Production from Ethanol by Yarrowia lipolytica

Isocitric acid exists in the form of four stereoisomers, of which only the threo-Ds-form (ICA) is a natural active compound, an intermediate of Krebs cycle, and suitable for nutritional and pharmaceutical use. In this paper, we propose a method for ICA production from ethanol by yeast Yarrowia lipolytica. The effects of temperature, pH of the medium, and aeration on the growth of the producer Y...

Effect of Plant Oils upon Lipase and Citric Acid Production in Yarrowia lipolytica Yeast

The nonconventional yeast Yarrowia lipolytica degrades very efficiently hydrophobic substrates to produce organic acids, single-cell oil, lipases, and so forth. The aim of this study was to investigate the biochemical behavior and simultaneous production of valuable metabolites such as lipase, citric acid (CA), and single-cell protein (SCP) by Yarrowia lipolytica DSM 3286 grown on various plant...

Lipid production by the oleaginous yeast Yarrowia lipolytica using industrial by-products under different culture conditions

BACKGROUND Microbial lipid production using renewable feedstock shows great promise for the biodiesel industry. RESULTS In this study, the ability of a lipid-engineered Yarrowia lipolytica strain JMY4086 to produce lipids using molasses and crude glycerol under different oxygenation conditions and at different inoculum densities was evaluated in fed-batch cultures. The greatest lipid content,...

Role of -Oxidation Enzymes in -Decalactone Production by the Yeast Yarrowia lipolytica
