Influence of the temperature on batch cultivation of Candida utilis IZ-1840 on a synthetic medium containing glycerol as the main carbon source

Influence of the initial glycerol concentration on the specific growth rate of Candida utilis cultivated on a synthetic medium containing glycerol as the main carbon source

“…We did not find a linear correlation between At/tf and I.t, as reported by Triboli et al (1994). Equation 2 however, obtained from our results clearly shows that there is a statistically significant correlation between At and t.t (see figure 1).…”

“…65 and 75,K2HPO4,1.42;KH2PO4,0.49;urea,2.51,MgSO47H20 ,4.50;Na2SO4,0.52;ZnSO4.7H20 ,0.042;biotin.HCl,4.0 x 10-6; the above substances were dissolved in citrate/citric acid buffer, pH = 4.5) added to the reactor --40 L; pH = 4.5; temperature = 30oc; air rate = 1.0 L.L'l.min-1; impeller speed:: 400 rev.min-1; anti-foam: UCON R (Union Carbide Corporation). The culture media composition were based on information published by Hong et al (1987) and Triboli et al (1994). Glycerol concentrations was measured by the anthrone method (Pons et a!.,1981).…”

Raw Glycerol as Substrate for the Production of Yeast Biomass

“…Subsequently, once the most appropriate strain was found, cultivations with different culture media ( Table 1) Triboli et al [16] were carried out using raw glycerol. In this case, the amount of raw glycerol to be added had its composition considered in order to result in the required substrate (glycerol) concentration.…”
