Summary: This study demonstrates the effective production of biohydrogen (bioH(2)) and ABE through ABE fermentation using sonication pretreated Chlamydomonas mexicana biomass as a cost-effective substrate. Sonication enhances the recovery and bioaccessibility of carbohydrates and proteins, resulting in higher yields of bioH(2) and volatile fatty acids. The study shows the efficient conversion of soluble carbohydrates and proteins into bioH(2) and ABE, which can be used for high-energy biofuel production with minimal waste generation.

Summary: This study provides evidence on the effectiveness of metabolically engineered C. beijerinckii NCIMB 8052 for fermenting LB-derived hydrolysates to produce acetone-butanol-ethanol (ABE). The engineered strain showed higher butanol and ABE production in non-detoxified hydrolysates compared to the wildtype strain, and even higher production in detoxified hydrolysates.

Summary: Coupled fermentation of Clostridium acetobutylicum and oleaginous yeasts was conducted to produce acetone-butanol-ethanol (ABE) and lipids from sugarcane molasses. The results showed that the ABE fermentation wastewaters could be effectively treated and the added value of the products could be increased through coupling with lipid-producing fermentation process. Different types of wastewaters were analyzed and classified based on their carbon source content and structure. Oleaginous yeasts, including Trichosporon dermatis and Lipomyces starkeyi, were cultured on the two types of wastewaters and their lipid productions and removals of COD and ammonia were evaluated. The findings suggest that Trichosporon dermatis performed well on both types of wastewaters, while Lipomyces starkeyi achieved the highest lipid production on Type-2 wastewater.

Summary: This study identified four orphan histidine kinases (HKs) that control sporulation and solventogenesis in Clostridium acetobutylicum. Single knockout of cac3319 halted sporulation at the initiation stage but increased butanol tolerance and production, while cac0437 knockout caused premature sporulation and inhibited the transition to solventogenesis, resulting in low butanol production.

Summary: Engineered microbial chassis using fermentation processes have the potential to replace environmentally damaging petrochemical feedstocks by recycling biomass-derived carbon into chemicals and fuels. Multiple marked auxotrophic strains of Clostridium acetobutylicum were created to allow rapid integration of heterologous genes at distinct loci using allele-coupled exchange. The system was demonstrated to successfully produce isopropanol by integrating synthetic acetone operon and a gene encoding secondary dehydrogenase into specific loci.

Summary: In this study, a kinetic model of acetone-butanol-ethanol (ABE) fermentation based on enzyme kinetics expressions was proposed. The model takes into account the effect of the co-substrate NADH as a modulating factor of cellular metabolism. The simulations obtained with the model showed a good fit to experimental data, surpassing previous models. The introduction of NADH in the model offers a basis for analyzing electrofermentation processes with Clostridium.

Summary: This study developed a three-staged repeated-batch immobilized cell fermentation to produce butanol from undiluted, non-detoxified sugarcane bagasse hemicellulose hydrolysates. Results showed that using bagasse as a carrier was more effective than using a 3D-printed carrier, leading to higher xylose utilization and more butanol derived from SBHH.

Summary: We developed a pH-based phenomenological model to predict the fermentative production of butanol from glucose using C. acetobutylicum in a batch system. The model describes the relationship between the dynamics of growth and the production of desired metabolites and the extracellular pH of the media. Our model was successful in predicting the fermentation dynamics of C. acetobutylicum and can be extended to represent the dynamics of butanol production in other fermentation systems.

Summary: This study evaluated the cocultivation of Clostridium acetobutylicum and Mucor indicus, which showed the potential to generate high yields of acetone-butanol-ethanol (ABE) and hydrogen from the organic fraction of municipal solid waste (OFMSW). The symbiosis between the fungus and bacteria led to high ethanol, butanol, and hydrogen yields without the need for starch hydrolysis. The cocultivation showed higher energy generation and economic potential compared to mono cultivation.

Summary: In this study, an exogenous regulatory strategy named oxidation-reduction potential (ORP) regulation was used to enhance butanol production. The findings showed that controlling the ORP value at -400 mV resulted in the highest butanol production, with increased yield and productivity. The study also investigated the physiological mechanisms of ORP regulation on butanol synthesis.

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.
