“…However, there is an urgent need for bioethanol fermentation from corn stover hydrolysate, with lower costs and higher efficiency (Mabee and Saddler 2010;Han et al 2011). Immobilization of yeast cells allows them to evenly distribute throughout the bioreactor, which reduces the negative impact of by-product metabolites that accumulate during bioethanol fermentation and enhances yeast cell stability (Ban et al 2002;AlvaradoCuevas et al 2013;Berlin et al 2006).…”

The use of low cost and abundant corn stover in yeast fermentation can reduce product costs. In this study, bioethanol was produced from a hydrolysate of corn stover using immobilized yeast. A kinetic model was established for the total reducing sugar consumption and the production of bioethanol. The parameter estimation for kinetic modeling considered the main process variables during bioethanol production from corn stover. Total reducing sugar concentrations decreased exponentially in the bioethanol fermentation for 6 h; consumption was more than 90%. To use kinetic modelling of yeast growth for bioethanol fermentation, the value of μmax reached 0.2891 h -1 , and the matrix inhibition constant (KIS) and production inhibition constant (KIP) were 8.9154 g/dm 3 and 0.00676 g/dm 3 , respectively. To use kinetic modelling of fermentation time on bioethanol, the maximum ratio of bioethanol production rate (qmax) reached 1.427 g/g•L. However, KIS was 2.813 g/dm 3 , and KIP was 0.0149 g/dm 3 .

“…A migração do grupo acila de 1,2-DAG para 1,3-DAG e 2-MAG para 1-MAG, que precedem a reação, promovem um rendimento elevado de biodiesel (Figura 9). 134 As lipases sn-1,3-específicas, tais como Rhizopus oryzae, 135 e Mucor circinelloides, 64 catalisam eficientemente a transesterificação do óleo vegetal para ésteres de etila com rendimentos superiores a 90%. Este elevado rendimento de transesterificação enzimática resulta da migração de resíduos acila para posições específicas na molécula de glicerol, pois mesmo sendo enzimas sn-1,3-específica, estas lipases são eficientes para clivar ácidos graxos de TAG, nas posições sn-1,3 promovendo a migração de resíduos acila da posição sn-2 para posições terminais (sn-1 e sn-3) no glicerol.…”

“…The high cost of the lipase enzyme seems to be the obstacle for commercially feasible enzymatic production of biodiesel fuels. In order to reduce the cost, Ban et al (2002) [26] created an alternative technique that involves the direct usage of microorganisms as whole-cell biocatalysts. Filamentous fungi expressing the lipase on the surface have raised the most robust whole-cell biocatalyst [17,27].…”

The present study investigates the different approaches of biodiesel production by exploiting low cost feedstocks such as organic wastes of frying oils (WFO) and wastes of beef fats (WBF). The aim was to compare not only two different sources of waste raw materials but also different approaches of biodiesel production. Biodiesel which refers to fatty acid methyl esters (FAME) was produced by both chemical and enzymatic transesterification. The characterization of the biodiesel produced by both approaches was performed according to the European standard EN 14214. The results showed that the biological method gave a richer FAME biodiesel through the catalysis of whole-cell lipase. However, for the chemical method, better biodiesel physicochemical properties were observed for the two raw materials. Therefore, it would be interesting to compromise by optimizing the biological biodiesel production approach in order to obtain a better quality in coherence with EN 14214 requirements.
