Brown pigments produced by Yarrowia lipolytica result from extracellular accumulation of homogentisic acid.
Yarrowia lipolytica produces brown extracellular pigments that correlate with tyrosine catabolism. During tyrosine depletion, the yeast accumulated homogentisic acid, p-hydroxyphenylethanol, and p-hydroxyphenylacetic acid in the medium. Homogentisic acid accumulated under all aeration conditions tested, but its concentration decreased as aeration decreased. With moderate aeration, equimolar con...
متن کاملAcid and Alkaline Extracellular Proteases of Yarrowia lipolytica
XPR2 and AXP1, coding for alkaline (AEP) and acid (AXP) extracellular proteases, have been sequenced for several strains. For XPR2, the three sequenced strains are not closely related and produce significantly different levels of AEP, yet the coding sequences are identical, and there is only a single nucleotide difference in one promoter suggesting that host physiology, not promoter differences...
متن کاملCharacterization of an Extracellular lipase from Yarrowia lipolytica
Lipases from different sources have distinct properties, such as specificity, stability and optimal operational conditions. Moreover, different conditions of lipase production may alter these enzyme properties. Therefore, the aims of this study were related to the evaluation of lipase activity of Yarrowia lipolytica IMUFRJ 50682 (isolated from Baía de Guanabara, Brazil) produced under submerged...
متن کاملYarrowia lipolytica in Biotechnological Applications
The nonconventional yeast Yarrowia lipolytica has been developed as a versatile and attractive tool for a large variety of biotechnological applications. This yeast has several physiological properties with industrial significance. Y. lipolytica uses hydrophobic substrates such as n-alkanes, oils, fats, and fatty acids as low-cost carbon sources. The yeast is able to produce a set of diverse ad...
متن کاملYarrowia lipolytica lipase production enhanced by increased air pressure.
AIMS To study the cellular growth and morphology of Yarrowia lipolytica W29 and its lipase and protease production under increased air pressures. METHODS AND RESULTS Batch cultures of the yeast were conducted in a pressurized bioreactor at 4 and 8 bar of air pressure and the cellular behaviour was compared with cultures at atmospheric pressure. No inhibition of cellular growth was observed by...
