Biomass species
WebAward activities would involve genetic sequencing and engineerin g of nonpathogenic Clostridia bacteria, species of which can produce n-butanol (a solvent) from biomass-derived su gars (i.e., glucose and xylose). Mutant strains would be engineered to be more resilie nt to environmental stressors and to increase n-butanol product ion rates. Mutant WebBiomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there …
