“…Furthermore, using factorial strategy to evaluate bioethanol production from Solanum lycicarpum fruit starch and Saccharomyces bayanus yeast, Morais et al (2019) obtained the highest bioethanol production when 1 % glucose equivalent was fermented in 48 h. Under these conditions the production yield was 92.13 %.…”

Bioethanol is a sustainable energy source to help reducing the emission of pollutants into the global environment. In order to cope with that, the ethanol production technologies and use of efficient and low-cost substrates are developed. The objective of this research was to evaluate fungal amylases in sweet potato starch for bioethanol production by Saccharomyces cerevisiae in the laboratory. Endomelanconiopsis endophytica (1.40 U/mL), Neopestalotiopsis cubana (1.67 U/mL) and Fusarium pseudocircinatum (1.11 U/mL) with high enzymatic activities were selected and their amylases were tested for activity on sweet potato starch for bioethanol production. Simultaneous saccharification and fermentation was performed at 30° C and pH = 5.0. 17.3 - 88.1 (%) of bioethanol that was produced and compared to the expected theoretical yield. Therefore, amylases from these fungi simultaneously inserted on sweet potato starch and S. cerevisiae are potentially useful for bioethanol production.

“…47 The variables affecting the whiteness index were A, B, C, AB, A 2 and B 2 (see Table 2). The positive coefficients B and C in equation (8) indicate that the H 2 O 2 concentration and the treatment time led to an increased whiteness index. For the a-cellulose content, all variables have an influence, except for BC and C 2 (see Table 2).…”

This work aims to optimize the industrial extraction conditions of cellulose microfibers (CMFs) from Washingtonia palm fiber for application in starch bio-composite films. The CMF extraction was a mixed process that combines caustic soda treatment with hydrogen peroxide bleaching in a stirred thermostatic bath. To study the yield, whiteness index and α-cellulose content, three variables were selected; NaOH and H2O2 concentrations and treatment time. The optimum was determined using a Response Surface Methodology (RSM) approach for samples treated for 70 min with 5.21% NaOH and 5.54% H2O2. The optimized CMF was used to produce Starch/CMF bio-composite films with higher mechanical and barrier performance, which increased by 300% and 31%, respectively. Moreover, its moisture absorption and water solubility decreased by about 24% and 26%, respectively after adding 20 wt% CMF. In fact, morphological results showed that the higher CMF in the Starch/CMF20 leads to the heterogeneous CMF distribution and agglomerates resulting in weakened starch films. As a result, the extracted CMF can be a competitive nanofabrication filler.

“…Biofuel as an alternative energy can be used as a substitute to fossil fuels [6]. Biofuel that has been developed as a substitute for fuel at this time is a type of bioethanol [7], [8], [9]. Bioethanol was made by using biomass fermentation techniques from sugar cane [10], corn [11], cassava [12], and so on.…”

Industrial sector has been focused on the transportation and automotive service due to their essential for many people in every daily life. Currently, almost everyone has a motorized vehicle which also has an effect on improving the country’s economy. On the other hand, this raises concerns about the occurrence of a global warming phenomenon. The more motorized vehicles were extremely impact on increasing the exhaust gasses that also have a negative impact to the environment, including carbon monoxide (CO) and carbon dioxide (CO2). Hence, this work tried to reduce the exhaust gas emission through the addition of ethanol and synthetic additive, namely patchouli oil. This case study was conducted using pertamax fuel with octane number 92. We analyzed five different optimization sample that consisting of S1, S2, S3, S4, and S5. Then, the several characterizations also carried out to these samples for supporting the results obtained i.e. density, viscosity, and surface tension. Also, the variation of engine rotation speed (in rpm) is utilized to determine the performance or the impact of the samples made to the environment. The results indicate that the pertamax sample mixed with ethanol and patchouli oil showed an optimal performance in S5, there is no detect of CO emission. Then, S3 for the lowest emission of CO2. Also, S3 for the highest efficient in fuel consumption. Hoping this work has an extremely impact for the reducing an exhaust emission in fuels and increasing the energy efficient of internal combustion engines
