For years, researchers have been looking for more sustainable sources for the raw materials used to make the products we use every day. Recently, biomass made from corn or sugarcane is used in manufacturing of a wide range of non-food products from plastics to fuel. However, use of food to make inedible products is controversial because it affects the food supply and can elevate food prices.
In this study, researchers looked at turning inedible biological byproducts, that scientists call lignocelluloslic biomass, to produce useful products to avoid the "food versus chemical" purposes.
They specifically looked at the process to use lignocellulosic biomass to produce butanediol (BDO) that is used to produce more than 1 billion pounds of spandex each year used in clothing and home furnishings. In 2010, it was estimated that spandex was used in 80 per cent of all clothing.
To establish the platform pathway, researchers examined the gene sequences from bacteria and fungi that turn the biomass into tricarboxylic acid (TCA) intermediates.
The researchers call this new metabolism "nonphosphorylative metabolism," which enables the production of useful products from TCA cycle with less than five steps, compared to previous 10 steps. Less steps in the process resulted in a 70 percent higher yield in production and a process that is overall better for the environment.
What excited researchers the most was that this pathway could be used for more than just producing BDO for spandex. It can be used to produce a variety of useful products.
