The use of corn as an expression host is an attractive system for the production of plant-made proteins. The use of plants lowers upstream costs making downstream the significant production cost. For some proteins, crossflow ultrafiltration could be a lower cost alternative. The potential for doing...

The pharmacokinetic profiles of monoclonal antibody charge variants are poorly understood because they differ only slightly from the “main” antibody species, are low in abundance, and extremely difficult to isolate in pure pools for intensive in vitro and in vivo studies. Because of this, the...

Carbon capture and sequestration (CCS) can be an important component of reducing worldwide CO2 emissions from stationary point sources, such as coal-fired power plants. Aqueous amines and ammonia are being demonstrated for CO2 capture in a temperature swing cyclic process. Solid sorbents can also...

Beer fermentations have traditionally been undertaken without the use of mechanical agitation with mixing being provided only by the CO2 evolved during the batch process. This approach has largely been maintained because of the belief in industry that rotating agitators would damage the yeast. In...

With the advancement of cellulosic ethanol technologies in recent years, more emphasis is being placed on the production of a sustainable supply of biomass for commercial scale facilities. These facilities will require significant supplies of biomass that will, in the southeast, come from private...

Currently, the complexity and scale dependency of land-use decisions and their impacts are not understood, defined, or described with adequate clarity to enable policy makers to develop strategies to ensure a sustainable bioenergy future with acceptable environmental and socioeconomic consequences...
