Was estimated using the correlation proposed at no cost convection about a strong sphere [27]. The diffusion coefficient of p-nitrophenyl palmitate substrate, 2.3 10-5 cm2s, required for the determination of kc was determined using the modified Stokes-Einstein equation [28]. The actual reaction order (n) was among 0 and 1 mainly because the substrate concentration of 0.74 mM was close towards the Km value of 1.five mM for immobilized lipase [20], and therefore the Mears’ criterion was over-estimated together with the assumption of n = 1. As more lipase was added, the radius with the lipase-bound MNP was improved together with the attachment of a lot more lipase to MNP in addition to a porous outer layer of lipase may possibly kind. The external mass transfer resistance, having said that, was not limiting because the calculated Mears’ criterion was a great deal smaller than 0.15 even though the radius was elevated by a number of folds. Nevertheless, the formation of an outer layer of lipase possibly triggered a decrease in theInt. J. Mol. Sci. 2013,effective diffusion coefficient NF-κB Formulation inside the layer [29]. The internal mass transfer might grow to be limiting. Because the characteristics with the lipase layer will not be known, the extent of internal mass transfer resistance is hard to estimate.

Effects of Dosage of Lipase-Bound MNP and Stepwise Addition of Methanol on the Conversion of FAME As shown in Figure 2, the conversion of FAME increased linearly with dosage of lipase-bound MNP inside the range examined. Maximal FAME conversion of 55.6 was observed with 40 (ww of oil) lipase-bound MNP, which was then utilised in later experiments. Figure 2. Effects of dosage of lipase-bound magnetic nanoparticles (MNP) around the conversion of fatty acid methyl esters (FAME). The dosage was expressed in weight percentage of waste cooking oil. The reaction was carried out at 40 for 72 h with water content material of ten (ww of oil). The molar ratio of methanol to oil was three:1; 3 separate additions at 0, 24 and 48 h, one third on the total quantity every single time.

J. Mol. Sci. 2013,methanol [30]. One typical technique to avoid such inhibition is always to add methanol in a stepwise style [30,31]. We examined the effect of stepwise addition at 0, 12 and 24 h or 0, 24 and 48 h (Figure three). Stepwise addition at 12 h-intervals resulted within a larger rate of FAME conversion in comparison using the 24 h-interval addition. Nonetheless, the conversions following 72 h had been related irrespective of the interval utilised. For later experiments, stepwise addition of methanol at 24 h-intervals was selected. Figure 3.
