TL;DR: No significant difference was observed in the weight loss profiles of switchgrass, wheat straw and eastern redcedar even though their cellulose, hemicellulose and lignin contents were considerably different, but biomass composition did significantly affect gas evolution profiles.

TL;DR: In this article, the feasibility of using two acetogenic bacteria to metabolize H 2 and CO 2 for the production of ethanol was evaluated in small-scale reactors to select a bacterium, feed gas composition and nutrient medium source to produce ethanol.

TL;DR: The possibility of extracting sugars from the invasive species of Eastern redcedar with high solid loadings and their conversion into ethanol is demonstrated and reduced glucan-to-glucose yields are demonstrated.

TL;DR: Observations indicate that P11 has a secondary alcohol dehydrogenase that enables it to reduce acetone to isopropanol, while P7 lacks this enzyme, which offers an opportunity for biological production of isOPropanol from acetone reduction in the presence of gaseous substrates (CO, CO2, and H2).

TL;DR: In this article, the critical factors that affect the integration of biomass gasification with syngas fermentation, such as carbon conversion efficiency, effect of trace gaseous species, H2 to CO ratio requirements, and microbial preference of carbon substrate, are thoroughly discussed.
