Renewable biobutanol production is receiving more attention toward substituting fossil-based nonrenewable fuels. Biobutanol is recognized as the top most biofuel with extraordinary properties as compared with gasoline. The demand for biobutanol production is increasing enormously due to application in various industries as chemical substituent. Biobutanol production technology has attracted many researchers toward implementation of replacing cost-effective substrate and easy method to recover from the fermentation broth. Sugarcane bagasse, algal biomass, crude glycerol, and lignocellulosic biomass are potential cost-effective substrates which could replace consistent glucose-based substrates. The advantages and limitations of these substrates have been discussed in this chapter. Moreover, finding the integrated biobutanol recovery methods is an important factor parameter in production of biobutanol. This chapter also concentrated on possibilities and drawbacks of obtainable integrated biobutanol recovery methods. Thus, successful process involving cost-effective substrate and biobutanol recovery methods could help to implementation of biobutanol production industry. Overall, this chapter has endeavored to increase the viability of industrial production of biobutanol.

The upgrading of ethanol to -butanol marks a major breakthrough in the field of biofuel technology, offering the advantages of compatibility with existing infrastructure while simultaneously offering potential benefits in terms of transport efficiency and energy density. With its lower vapour pressure and reduced corrosiveness compared to ethanol, -butanol is easier not only to manage but also to transport, eliminating the need for costly infrastructure changes. This leads to improved fuel efficiency and reduced fuel consumption.

Tannin-containing sorghum grains, suitable for acetone-butanol-ethanol (ABE) production by Clostridium acetobutylicum, have required pretreatment to eliminate tannins inhibiting the strain's amylolytic activity. This study investigates biobutanol production enhancement by immobilizing enzymes on polydopamine-functionalized polyethersulfone (PES) membranes with magnetic nanoparticles for Separated Hydrolysis and Fermentation (SHF) and Simultaneous Saccharification and Fermentation (SSF) processes. After multi-stage hot water treatment, TG3 sorghum (from the third stage) was used, where the enzyme-immobilized PES membrane produced 4.

Article Synopsis
- Acetone-butanol-ethanol (ABE) fermentation can produce bio-based 1-butanol from agricultural byproducts, which are low-cost and available year-round, addressing the issue of high feedstock costs in bio-butanol production.
- Milling byproducts like wheat red dog (WRD) and rye second flour (RSF) were found to contain high levels of glucan, primarily starch, making them suitable substrates for ABE fermentation by solventogenic clostridia.
- The strain Clostridium beijerinckii NCIMB 8052 performed the best in producing butanol, achieving titers up to 9 g/L in semi-continuous fermentation with a combination of WRD and rye waste,

Article Synopsis
- - Industrialization and globalization have heightened the demand for petroleum products, leading to greater fossil fuel use and greenhouse gas emissions, which calls for sustainable alternatives.
- - Algae are emerging as a promising source for biofuels, regarded as third-generation biofuels due to their high biomass production and multiple derivable fuels, like bio-hydrogen and bio-ethanol, using various processing methods.
- - Despite challenges like high cultivation costs, the potential of algae-derived biofuels can be enhanced through the use of byproducts, paving the way for more economical and environmentally sustainable energy solutions.
