Biobutanol production from hydrothermal pretreated Psidium guajava lignocellulosic biomass and comparison with sugarcane straw.

The objective is to synthesize biobutanol from lignocellulosic biomass that has been hydrothermally processed using Clostridium acetobutylicum and to evaluate the process in comparison to sugar cane straw. Research tools and techniques: Hydrothermal pretreatment, drying, and grinding into a fine powder of Psidium guajava leaves were all part of the research process. After that, the sample was acid hydrolyzed using diluted sulfuric acid to get the sugar yield needed, and then biobutanol was produced by fermentation with C. acetobutylicum. Each of the two groups had seven samples for the experiment; the G-power was 80% and the coincidence intervals were 95%. The results show that a biobutanol production yield of 5.5 g/L was reached under ideal circumstances using Psidium guajava as the substrate. In addition, the examination of the two-tailed t-test showed a p-value of 0.04 (p<0.05), which is statistically significant. In conclusion, there is a significant potential for the ABE fermentation process to become more efficient when lignocellulosic biomass is used as a substrate for biobutanol synthesis.
