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: In recent years, there has been significant attention given to the environmental impact of olive mill waste. However, there is still limited knowledge about the effects of olive mill wastewater and contaminated soil on non-target soil organisms. This study investigated the effects of these wastes on the survival, reproduction, neurotoxicity, oxidative stress, and available energy of the springtail F. candida. The results showed that the contaminated soil had higher toxicity compared to the wastewater, affecting survival and reproduction. Additionally, neurotoxicity, oxidative stress, and changes in available energy were observed. These negative effects are likely due to the high phenol content in the wastes. The findings suggest that different biomarkers should be considered in the ecotoxicological assessment of various wastes to understand their mechanisms of action.

Summary: A comparative study was conducted on the biosorption capacity of cyanobacteria Spirulina platensis and yeast Saccharomyces cerevisiae towards dysprosium ions. The experiment evaluated the effects of pH, concentration, time, and temperature on biosorption capacity. Results showed that both biosorbents exhibited efficient and pH-dependent dysprosium removal. Adsorption data fitted well with the Langmuir model and the kinetics followed the pseudo-second-order and Elovich models. The maximum biosorption capacities were 3.24 mg/g and 5.84 mg/g for Spirulina platensis and Saccharomyces cerevisiae, respectively. Thermodynamic analysis revealed the spontaneous nature of dysprosium biosorption, with exothermic behavior for Saccharomyces cerevisiae and endothermic behavior for Spirulina platensis. Thus, biological sorbents can serve as an eco-friendly alternative for dysprosium recovery from wastewater.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
