Biomass and Bioconversion Topics impacted by Biotechnology

• Fundamental Science– Photosynthesis, Photosynthetic microorganisms

• Biomass Crops– Targeted Breeding

• Use of Genetic Maps and micro-propogation to accelerate crop development

• Gene insertion for – within plant manufacture of desired products– Pesticide/temperature/water use efficiency– Photosynthesis

• Bioconversion– Current major direction is ethanol from lignocellulosics
