Summary: The present study developed a cost-effective, energy-saving, and ecofriendly methodology for producing ethanol from citrus fruit waste. This involved pretreating the waste through physical means, followed by enzymatic hydrolysis and fermentation. The process resulted in the production of 40.1 g/L ethanol in 48 hours, and an additional fed batch step increased the ethanol yield to 52.3 g/L. The study successfully achieved its objectives of sustainability.

Summary: The need for an alternative energy source to fossil fuel has led to the search for reliable and sustainable sources that can address environmental challenges and stabilize energy prices. Biofuel, particularly bioethanol, has been identified as a superior alternative, but its high production cost remains a major challenge. Research is focused on finding cheap and sustainable feedstock for bioethanol production, with a current interest in lignocellulosic waste. This review discusses the conversion of lignocellulosic waste to bioethanol, the pretreatment steps involved, and the challenges, prospects, and economic aspects. While biological treatment appears promising, there are still some challenges that can be managed. Developing countries have significant opportunities for biofuel production cost reduction. Enzyme production cost has been identified as a challenge to the economic viability of lignocellulosic bioethanol, but the development of an efficient biocatalyst system for simultaneous saccharification and fermentation (SSF) and consolidated biomass processing may help overcome this challenge. In conclusion, effectively utilizing lignocellulosic waste in an efficient biocatalyst system can provide an economically viable means to overcome the challenges posed by fossil fuel.

Summary: This study demonstrated the production of bioethanol from lignocellulosic residue through simultaneous saccharification and fermentation. Increasing solid content improved the ethanol concentration, yield, and productivity, but a decrease was observed at the maximum solid concentration. The co-application of two enzyme complexes positively affected the conversion efficiency.

Summary: In this study, bread waste was used as a feedstock for fermentative production of ethanol and biomethane. Glucose was obtained by acid and enzymatic saccharification of bread waste, and then fermented into ethanol. The solid residue after fermentation was subjected to anaerobic digestion to produce biomethane. The study showed that bread waste is a promising feedstock for sustainable biofuel production.

Summary: The large consumption of non-renewable fossil fuels has led to energy depletion and environmental pollution, necessitating the production of renewable biofuels as an effective alternative to alleviate the energy crisis. Saccharomyces cerevisiae, as an ideal type of biofuel, has gained attention for its high efficiency in bioethanol synthesis. This study provides a systematic summary of the advantages of S. cerevisiae in biosynthesis, discusses research strategies and existing bottlenecks, and proposes reasonable prospects for its bioethanol synthesis.

Summary: This study investigated the relationship between wild type and engineered strains of the same microorganism in terms of kinetic parameters, and proposed a set of correction factors to estimate kinetic constant values for species or strains for which they are not available. The results showed a correlation between wild type and engineered strains, with specific substrate limitation constants being higher in the engineered strains. These correction factors were found to be conserved and could serve as a guide for estimating kinetic constants in other species or strains.

Summary: The present study optimized the simultaneous saccharification and fermentation process for bioethanol production from corn cobs. It characterized ten different corn genotypes in terms of chemical composition and found that corn genotype PMH10 had high cellulose and low lignin content. Sodium hydroxide pretreatment increased cellulose content and decreased hemicelluloses, lignin, and ash content in the treated cob residues. The optimization of SSF process showed that maximum ethanol concentration could be achieved under certain conditions.
