BIOSORPTION OF Cu(II) BY LIVE AND DEAD CELLS OF Yarrowia lipolytica BIOSORPCJA Cu(II) PRZEZ ŻYWE I MARTWE KOMÓRKI Yarrowia lipolytica
The biosorption characteristic of Cu(II) using live and dead cells of Yarrowia lipolytica as biosorbents have been investigated in the present research. Biosorption of Cu(II) was enhanced with an increase in pH, temperature, agitation, contact time and initial concentration of the metal ion. It was observed that dead and live biomass efficiently removed copper at 30 min at an initial pH of 5.0....
متن کاملCadmium biosorption by yeast, Candida tropicalis CBL-1, isolated from industrial wastewater.
The present study is aimed at assessing the ability of metal-resistant yeast, Candida tropicalis CBL-1, to uptake metal from liquid medium. The minimum inhibitory concentration of Cd(II) against Candida tropicalis CBL-1 was 2,800 mg/L. The yeast could also tolerate Zn(II) (3,100 mg/L), Hg(II) (2,400 mg/L), Ni(II) (2,200 mg/L), Cr(VI) (2,000 mg/L), Pb(II) (1,100 mg/L), and Cu(II) (2,200 mg/L). T...
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 کاملCadmium biosorption by Saccharomyces cerevisiae.
Cadmium uptake by nonliving and resting cells of Saccharomyces cerevisiae obtained from aerobic or anaerobic cultures from pure cadmium-bearing solutions was examined. The highest cadmium uptake exceeding 70 mg Cd/g was observed with aerobic baker's yeast biomass from the exponential growth phase. Nearly linear sorption isotherms featured by higher sorbing resting cells together with metal depo...
متن کاملImproving the thermostability of lipase Lip2 from Yarrowia lipolytica.
Yarrowia lipolytica lipase Lip2 (YlLip2) is a highly versatile biocatalyst. However, its practical use is often hampered by its low stability. Here three complementary protein engineering strategies were used to improve the thermostability of this enzyme. The first strategy was error-prone PCR based directed evolution, which resulted in a YlLip2 variant with a 2.5-fold longer half-life of therm...
