Summary: Biobutanol is considered a new generation fuel due to its physical and chemical features that make it more efficient than other biofuels. The production of biobutanol from lignocellulosic biomass through anaerobic fermentation faces challenges such as high production cost, long time consumption, and sporulation stage hindering solvent production. However, through preparation methodology, reactor design, and genetically engineered microbes, these difficulties can be overcome. This review provides an overview of the current troubles in biobutanol production and presents research activities that aim to solve them, including genetic engineering approaches and computational methods. Additionally, it discusses the characteristics, engine compatibility, and commercialization difficulties of biobutanol.

Summary: The main hurdles in mechanized transportation are the depletion of fossil fuels and the high cost of alternative plant-based substrates for producing biofuels. Biofuels emerged as effective alternatives to reduce pollution caused by greenhouse gas emissions. Microalgae, as a third-generation feedstock, are an excellent resource due to their fast growth rate and higher carbohydrate content, providing a solution to the challenges faced by conventional agricultural crops.

Summary: This study investigated the effects of combining multiple types of lignocellulosic biomass with nitrogen-rich wheat bran on ABE fermentation. The results showed that the optimal mixing ratio of wheat bran with different types of lignocellulosic biomass was 1:1, 1:4 and 2:3, respectively. Addition of corn steep powder significantly enhanced sugar consumption and solvent concentration. Integration of pervaporation with ABE fermentation facilitated timely removal of butanol and alleviated product inhibition, resulting in comparable total solvents concentration to fermentation with synthetic medium.

Summary: This study successfully recovered butanol from the model ABE aqueous solution using an integrated gas stripping and novel ABE recovery system. The results showed that nitrogen gas achieved the highest stripping efficiency, while H-2 gas achieved the highest condensation efficiency. The recovered butanol had high concentrations and can be further purified at reduced energy cost.

Summary: The co-fermentation of mixed sugars for butanol production is a promising approach, and C. saccharoperbutylacetonicum DSM 14923 shows potential and effective application in this process. The study found that the best-performing fermentation medium had a CHH25/SCM75 ratio, with 97% sugar consumption and no inhibitory effect of undissociated acetic acid at pH 5.5-6.5.

Summary: A 5-L pilot-scale packed-bed bioreactor with integrated in situ extraction/gas-stripping was developed for automated ABE fermentation. The bioreactor exhibited robustness during a continuous run of 770-h. Optimal inoculation protocols were developed to improve butanol productivity and bacterial growth. Inhomogeneous bacterial growth within the packed bed highlighted the need to address this issue for improved efficiency.

Summary: The objective of this study was to enhance biobutanol production through the integration of rare earth element stimulation, activated carbon adsorption, and cell immobilization in acetone-butanol-ethanol fermentation. Gadolinium (Gd(III)), among eight selected rare earth elements, significantly stimulated cell growth and biobutanol biosynthesis when added as a trace supplement in the fermentation medium (1 x 10-5 M). Activated carbon particles were used to mitigate the toxic effects of biobutanol on bacterial cells through adsorption, with adsorption kinetics following Pseudo-first-order dynamics and Freundlich isotherm models. Immobilization of bacterial cells on the surface of volcanic stones prevented competitive adsorption between bacterial cells and biobutanol on activated carbon particles. The developed strategy resulted in a total biobutanol yield of 15.26 +/- 0.43 g/L, which was 73.20 +/- 12.69% higher than that of common fermentation with free bacterial cells.

Summary: The adsorptive vapour phase separation of 1-butanol from a synthetic ABE mixture using pure silica zeolites with different pore structure and topology showed that Si-STT zeolite has remarkable selectivity towards 1-butanol, unaffected by the presence of water or CO2, and is an excellent and robust adsorbent for achieving high purity and recovery rates in conditions close to ABE fermenter headspace.

Summary: An integrated bioprocessing approach was used to enhance energy recovery from biodegradable municipal solid waste. Clostridium acetobutylicum and Enterobacter aerogenes were cocultivated for coproduction of hydrogen, 2,3-butanediol, and acetone-butanol-ethanol (ABE). The remaining solids were used for biomethane production. The study demonstrated the potential of the integrated fermentation-anaerobic digestion bioprocess for biofuels production from zero-cost substrate.
