Effect of Nickel Contamination on the Growth of Oleaginous Yeasts in Hydrolisates of Arundo Donax
Hydrolysates of Arundo donax, a crop offering high productivity in contaminated orsalinized soils with no inputs of irrigation and agrochemicals, were used in a discontinuous fermenter to grow the oleaginous yeast Lipomyces starkey, to obtain microbial oils potentially useful for the production of 2...

| description | Hydrolysates of Arundo donax, a crop offering high productivity in contaminated orsalinized soils with no inputs of irrigation and agrochemicals, were used in a discontinuous fermenter to grow the oleaginous yeast Lipomyces starkey, to obtain microbial oils potentially useful for the production of 2nd-generation biodiesel.
A mixture of fermentable sugars was obtained by steam-explosion and subsequent enzymatic hydrolysis of the lignocellulosic materials. The concentration of Ni2+ ions and of inhibitors of the microbial growth significantly affected both the biomass and the triglyceride yields. The microbial lipids produced were compatible with the synthesis of an automotive-grade biodiesel.
A physico-mathematical model, developed todescribe the biomass growth, demonstratedthat the concentration of heavy metals affected the maximum biomass concentration,though its influence on the specific growthrate of the yeasts was not significant. |
