“…Keywords: evolutionary adaptation, xylose, Kluyveromyces marxianus, ethanol, xylitol inTrODUcTiOn Several environmental issues including global warming, climate change, CO2, and CO emission are major concern nowadays, which are primarily caused by conventional transportation fuels and burning of the crop residues (Kumar et al, 2009). To cure these issues, a sustainable process should be developed to produce alternative transportation fuel along with utilization of crop residues.…”

“…To cure these issues, a sustainable process should be developed to produce alternative transportation fuel along with utilization of crop residues. Lignocellulosic ethanol production could be a better solution to resolve these issues, which has already been proved as better alternative to conventional fuels including gasoline (Kumar et al, 2009(Kumar et al, , 2010. Lignocellulosic waste has also been found as a better source for economic bioethanol production due to its abundance and low cost (Kumar et al, 2010;Sharma et al, 2016).…”

“…Furthermore, SSF is a major application using this strain, which takes place at higher temperature due to the maximum cellulases activity at 50°C (Arora et al, 2015). Moreover, requirements of heating and cooling process during saccharification and fermentation using mesophiles increases the cost of process (Kumar et al, 2009). K. marxianus shows great potential over mesophiles including no cooling requirement during SSF, solvent tolerance, and minimum risk of contamination, which proves it to be a better alternative for sustainable process development (Kumar et al, 2009;Arora et al, 2017).…”

The evolutionary adaptation was approached on the thermotolerant yeast Kluyveromyces marxianus NIRE-K3 at 45°C on xylose as a sole source of carbon for enhancement of xylose uptake. After 60 cycles, evolved strain K. marxianus NIRE-K3.1 showed comparatively 3.75-and 3.0-fold higher specific growth and xylose uptake rates, respectively, than that of native strain. Moreover, the short lag phase was also observed on adapted strain. During batch fermentation with xylose concentration of 30 g l −1, K. marxianus NIRE-K3.1 could utilize about 96% of xylose in 72 h and produced 4.67 and 15.7 g l −1 of ethanol and xylitol, respectively, which were 9.72-and 4.63-fold higher than that of native strain. Similarly, specific sugar consumption rate, xylitol, and ethanol yields were 5.07-, 1.15-, and 2.44-fold higher as compared to the native strain, respectively. The results obtained after evolutionary adaptation of K. marxianus NIRE-K3 show the significant improvement in the xylose utilization, ethanol and xylitol yields, and productivities. By understanding the results obtained, the significance of evolutionary adaptation has been rationalized, since the adapted culture could be more stable and could enhance the productivity.

“…Elixir is an oral solution drug form that has alcohol as a cosolvent; meanwhile, tincture is ethanol or a hydroalcohol-containing solution made out of plant or chemical compounds [5]. Ethanol also has the potential of becoming a next-generation renewable automobile fuel, such as lignocellulose biomass [6].…”

Fermentation of Bioethanol From the Biomass Hydrolyzate of Oil Palm Empty Fruit Bunch Using Selected Yeast Isolates

Objective: The purpose of this research was to investigate the potential of yeast-producing bioethanol from few type of grapes and durians. Methods:The isolation of potential yeast was carried out from five different types of fruits, namely, red grape, black grape, durian Medan, durian Bangkok, and durian Monthong. Optimum fermentation condition was obtained by comparing shaking and non-shaking, detoxifying the hydrolysate, varying temperature, and concentration of N source in the culture medium. Results:The results of an analysis using gas chromatography showed that the ideal conditions for the fermentation of bioethanol were at a temperature below room temperature (+220°C), without shaking, using the hydrolysate, without detoxification, and with a 1% concentration of ammonium acetate as a source of N. Among the isolates, isolate DM1 obtained from durian Medan showed a strong potential to produce bioethanol but at lower levels than Saccharomyces cerevisiae. The concentration of ethanol produced was 0.241%. Conclusion:A yeast isolate with a strong potential to produce bioethanol was discovered as the DM1, which isolated from Medanese durian. The isolate produced 0.241% bioethanol. However, fermentation optimization efforts using an oil palm empty fruit bunch hydrolysate substrate did not yield higher concentrations.

“…Most of the potential ethanologens that are in industrial use belong to mesophilic group (28-35º C) [1,2,3,4,5]. However, bioethanol production by thermophiles has certain advantages over mesophiles and it needs to be investigated for ethanol production.…”

The growth of thermotolerant/ thermophilic ethanol producing yeast and the fermentation processes using sugary substrates are exothermic processes. If the fermenters are heat insulated, the requirement of heat for maintaining the fermentation broth for ethanol production may be reduced considerably. The heat generated due to growth of thermotolerant yeast Kluyveromyces sp. IIPE453 was found to be 652kJ mol -1 at 50°C using glucose as a substrate. The heat generated due to ethanol formation by Kluyveromyces sp. IIPE453 was found to be 132.54kJ mol -1 of sugar consumed or 67.84kJ mol -1 of ethanol produced at 50°C using sugarcane molasses as substrate. This heat would be sufficient for maintaining the desired temperature, if insulated fermentation systems are used. Therefore, no additional heat would be required to maintain the temperature in fermentation process by thermotolerant yeast at 50°C .
