Economics of sugar production with Trichoderma reesei Rutgers C-30. [Corn stover]
The economics of sugar production from bioconversion of corn stover utilizing cellulase obtained from Trichoderma reesei strain Rutgers C-30 were investigated. The cost of manufacturing sugar is 10.5 cents per pound. This reduced cost is due to cellulase activities ranging from 7 to 14 IU/ml from batch cultures. Hydrolysis can be carried out at substrate concentrations up to 25% and give product streams containing up to 9% sugars. Conversions up to 61% of theoretical have been observed. A sensitivity analysis indicates that sugar can be produced at near competitive prices from corn stover costing $0 to $50 per ton. By utilizing new fermentation technology, sugar at these prices can be used to product 95% alcohol at a cost ranging from $1.80 to $3.00 per gallon.
