GM Plants Reduce the Cost of Biofuel Production
A new study, recently published in the journal Science, explains that by genetically modifying the plants, much of the lignin can be removed, avoiding the need to soak the biomass in hot acid, and greatly reducing the overall cost of the biofuel production process.
By genetically modifying plants to remove a key gene needed for lignin production, the scientists discovered that the plants grew with far less lignin, and that 80% of the cellulose within the plant could then be extracted without the need for the acid treatment. Only 18% of the cellulose in a normal plant can usually be extracted without the acid treatment.
