ignocellulosic biomass is the most abundantly available raw material on the Earth for the production of biofuels. The

conversion of lignocellulose into renewable energy and more valuable chemicals has been limited. Several methods

for increasing the conversion of lignocellulose into biogas by pretreating the feedstock have been developed, but all of the

existing methods have large economic penalties, e.g. disposal of toxic wastes and greatly increased capital and operating

costs. The discovery and characterization of Caldicellulosiruptor microbes, extremophilic organisms capable of solubilizing

lignocellulose, suggested a possible solution to the economic problem of pretreatment. For example, researchers (Blumer-

Schuette et al., 2014) have found that up to 90% of the biomass in switchgrass could be solubilized by

C. bescii,

thus providing

proof of concept. Beginning in 2014, recognizing the potential for anaerobic digestion of lignocellulose for biogas production,

a multidisciplinary team including a biochemist, chemist, microbiologist and agricultural engineer, from Brigham Young and

Utah State Universities has been conducting experiments to determine if we could break down other lignocellulose feedstocks

for later anaerobic digestion. Our experimental results have been very encouraging in providing proof of concept that anaerobic

digestion of lignocellulose, something that has never been done in a commercially viable way, may be both possible and

attainable. However, the commercialization and scaling up of lab experiments is not simply a process of buying bigger tanks but

requires cross-discipline expertise in order to overcome the inevitable differences between 20-1000 mL lab experimentation

and a multiple m3 system. This presentation will report the results of work we have done to take the process from the lab to the

market; the hurdles to scaling and commercializing the anaerobic digestion of lignocellulose in an economically viable way.
