Abstract

Humans discovered the fire when they needed to cook, wheels when they needed to travel and fuel when they needed to escalate all this process. This evolution of humanity increased pressure on nature, which has enough to satisfy our need but not our greed. Humans bathed in a new shower of change with every coming generation. Fuel is one of the essential parts of this change, and hence, a cloud of exhaustion keeps on covering its reserves, and the day is not too far when this cloud will bring the ultimate shower of change which will exhaust all the fuel reserves. Hence, the need to shift to an unconventional source of fuel production has risen. This paper mainly focuses on providing a solution to this continued exploitation of conventional fuel production sources by suggesting a viable alternative method. One such alternative can be biofuel, which is considered one of the most promising alternative fuel production sources. However, it too has its challenges like a proper selection of fee

Conclusion

Among the so many xylose-fermenting yeasts, the most promising one is Pichia stipitis owing to its ability to ferment xylose with high ethanol yield and very low to none xylitol accumulation. It shares a close relationship with the other yeasts,making endosymbiontof passalid beetles that inhibit and decompose white rotten hardwood (Abdu Yusuf and Inambao, 2019; Behera et al., 2014; Agbogbo and Wenger, 2006; Ghosh and Ghose, 2003). This particular yeast is the best xylose-fermenting microorganism compared to any known microorganism. In addition to xylose, this can consume other sugars found in wood as well. Theoretically, the fermented lignocellulosic sugars by P. stipitis can approach 80% yield. Because of its natural ability to ferment hydrolysates along with all the genetic tools available, it has become a major choice by scientists and producers to convert lignocellulose into fuels or other chemicals (Ruchala et al., 2020). A yeast group called 'respiro-fermentative' yeast tells us
