“…Previous study has also shown that in the bioethanol production from steam-pretreated softwood based on SSF using the S. cerevisiae strain, increased ethanol concentration leads to growth inhibition [31]. Therefore, we considered that determining the ethanol tolerance-related genes of P. kudriavzevii is important because genetic engineering may be needed to avoid the toxicity of the high concentrations of ethanol produced in the cells [34]. Thus, we tried to confirm the ethanol tolerance capacities of strains NBRC1279 and NBRC1664 based on the draft genome sequences.…”

Simultaneous saccharification and fermentation (SSF) is capable of performing enzymatic saccharification and fermentation for biofuel production in a single vessel. Thus, SSF has several advantages such as simplifying the manufacturing process, operating easily, and reducing energy input. Here, we describe the application of Pichia kudriavzevii NBRC1279 and NBRC1664 to SSF for bioethanol production. When each strain was incubated for 144 h at 35 °C with Japanese cedar particles, the highest ethanol concentrations were reached 21.9 ± 0.50 g/L and 23.8 ± 3.9 g/L, respectively. In addition, 21.6 ± 0.29 g/L and 21.3 ± 0.21 g/L of bioethanol were produced from Japanese eucalyptus particles when each strain was incubated for 144 h at 30 °C. Although previous methods require pretreatment of the source material, our method does not require pretreatment, which is an advantage for industrial use. To elucidate the different characteristics of the strains, we performed genome sequencing and genome comparison. Based on the results of the eggNOG categories and the resulting Venn diagram, the functional abilities of both strains were similar. However, strain NBRC1279 showed five retrotransposon protein genes in the draft genome sequence, which indicated that the stress tolerance of both strains is slightly different.

“…Several studies have shown that these conditions play a crucial role in the stress tolerance of furan molecules as one of the enzymes responsible for the conversion of 5-HMF and furfural is aldehyde dehydrogenase [64]. Furthermore, numerous studies [65][66][67][68] observed a membrane damage due to furan molecules. Consequently, a membrane thickening could prevent or limit this effect.…”

“…Balta (2021), It is reported that modulation of the expression of ethanol producing and coordinated genes is necessary to increase the production of a simple compound such as ethanol [120]. S. cerevisiae has an important place because it has the highest ethanol tolerance capacity and wide pH range among all bacteria and yeasts [121]. Due to its special character, it reduces the cost of fermentation and distillation by reducing contamination.…”

When biofuels are used as an energy source, they are accepted as a renewable energy source that is safe for the environment and can replace fossil fuels at the same time. Additionally, using of organic materials obtained from plants and animals as biofuel is more advantageous compared to the formation of fossil fuels over hundreds of years. Therefore, biomass containing within itself substances such as sugar, starch, oil and cellulose, which have high energy availability, are considered as raw materials. While biodiesel is obtained from organic materials containing oil, ethanol and similar biofuels are generally obtained from organic materials containing sugar and starch. All these production stages vary depending on factors such as each plant species and variety, the amount of sugar contained in plants or sugar structures, the fermentation microorganisms used or the pretreatments applied. In this study, information is given about the stages of bioethanol production from grains and the issues affecting bioethanol yield.
