The liquid biofuel bioethanol is widely produced worldwide via fermenting sugars extracted from a variety of raw materials, including lignocellulose biomass, one of the world’s most abundant renewable resources. Due to its recalcitrant character, lignocellulose is usually pretreated by mechanical, chemical, and biological methods to maximize sugar recovery. Pretreated lignocellulose biomass undergoes a fermentation process performed sequentially or simultaneously to saccharification. The different fermentation strategies (e.g., separate or simultaneous hydrolysis and fermentation or co-fermentation) and conditions (e.g., inoculum type load, agitation, temperature, and pH) affect ethanol yield. Genetic modification of the inoculum has been focused recently to improve ethanol tolerance and as well as to use different sugars to enhance the performance of the microorganisms involved in fermentation. Nonetheless, these improvements result in a substantial increase in costs and have certain environmental costs. This review offers an overview of advancements in bioethanol production, with a primary focus on lignocellulosic feedstock, while also considering other feedstocks. Furthermore, it provides insights into the economic, social, and environmental impacts associated with bioethanol production.

“…In addition, it is used as a raw material for ethanol production in Brazil, which is the largest producer of cane sugar in the world (Snyman, 2004;López-Ortega et al, 2021). Similar to other food crops, the yield of sugarcane is seriously affected by various viral diseases.…”

Various RNA viral diseases on sugarcane result in yield loss and decreased sugar content. Breeding new varieties with virus resistance is the main goal of the sugarcane breeding program. Both single-stranded and double-stranded RNA viruses generated a double-stranded RNA replicative form (RF) during the replication cycle progress. While double-stranded RNA-specific ribonuclease (PAC1) encoded by the Pac1 gene (from Schizosaccharomyces pombe) can recognize and degrade double-stranded RNA specifically without any sequence, the expression of PAC1 in transgenic sugarcane may successfully develop virus-resistant sugarcane. In this research, we first expressed the PAC1 in prokaryotic cells. Then, double-stranded RNA RF of sugarcane's streak mosaic virus (SCSMV) was artificially synthesized. The degradation activity of the PAC1 was successfully tested by mixing the PAC1 protein and the double-stranded RNA RF. After that, the Pac1 gene was ligated to a plant expression vector and was then introduced into a virus-sensitive sugarcane cultivar by using Agrobacterium tumefaciens-mediated transformation method. Transgenic plants were challenged by inoculating with SCSMV. Results showed that although all the transgenic lines were infected by SCSMV, the mosaic symptoms that appeared on the leaves were significantly milder than that of the wild type. All transgenic shoots showed significantly lower viral loads and attained greater heights than wild-type shoots. This research provided a new pathway for breeding new varieties of sugarcane with virus resistance.
