Summary: This study investigates the high gravity fed-batch simultaneous saccharification and fermentation (FB-SSF) of sequentially pretreated sugarcane bagasse (SCB) for enhanced bioethanol production, using the inhibitor tolerant Kluyveromyces marxianus JKH5 C60. The optimized lab-scale FB-SSF, with intermittent feeding of SCB and enzyme, resulted in maximum ethanol titer, efficiency, and productivities of 73.4 g/L, 78%, and 3.0 g/L/h, respectively, after 72 h in the presence of inhibitors. Additionally, fermentation of pentose rich dilute acid hydrolysate of SCB by Pichia stipitis NCIM 3499 yielded an ethanol titer of 6.8 g/L. The overall ethanol yield during the developed process was 260.1 g/kg native SCB, indicating the industrial potential of this bioethanol conversion process.

Summary: The study on converting horse manure into bioethanol using acid-alkaline pretreatment and enzyme hydrolysis methods showed that alkaline pretreatment had higher sugar recovery yield and higher bioethanol productivity compared to acid-enzyme hydrolysates. The presence of lower amounts of toxic compounds in alkaline-enzyme hydrolysates may contribute to the higher bioethanol productivities as compared to acid-enzyme hydrolysates.

Summary: The European Green Deal is a set of policy initiatives aimed at achieving climate neutrality by 2050 through a green transition. In the pulp and paper industry, upgrading residues into value-added products within the forest-based circular economy model has been a focus. This study explores the possibility of using bark, a high volume residue in factories, for cellulosic ethanol production instead of burning it for energy generation. By implementing simultaneous saccharification and fermentation (SSF) in the bioethanol production process, the study found that longer pre-saccharification stage resulted in higher productivity and shifting from a batch to a fed-batch configuration further improved the overall productivity and bioethanol concentration.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
