• USDA scientists use commercial enzyme to improve grain ethanol production

  A commercial enzyme could reduce overall costs linked with producing ethanol from grain, and also reduce associated emissions of greenhouse gases, according to a study by U.S. Department of Agriculture (USDA) scientists and colleagues.The researchers found that the enzyme helps extract water from an more

• A high-yield biomass alternative to petroleum for industrial chemicals

  A team of University of Massachusetts Amherst chemical engineers report in Science that they have developed a way to produce high-volume chemical feedstocks including benzene, toluene, xylenes and olefins from pyrolytic bio-oils, the cheapest liquid fuels available today derived from biomass. The ne more

• Increased productivity for downstream processing of biotherapeutics
  

  Polymer-based chromatographic resins featuring high mechanical and chemical stability and high protein binding capacities can help to increase the throughput and robustness of biopharmaceutical manufacturing processes. Advances in genetic engineering and cell culture technology have raised upstream productivity in the production of recombinant proteins. Increased titres of up to 10 g/l stress the need for highly efficient and robust downstream processes (DSP). Most industrial bioprocess development groups apply generic DSP platforms that are designed to purify various candidates of the same class of proteins applying the same process design. Besides various filtration and virus inactivation steps, they usually involve two or three chromatographic unit operations with orthogonal separation modes. The use of high capacity chromatographic resins can help to overcome the DSP bottleneck by increasing process throughput and robustness more

• Sum parameters "on trail"
  

  Identification of organic pollutants in wastewater is essential for performance evaluation, construction and operation of a wastewater treatment plant. Several parameters are currently used in wastewater analysis applications. The advantages of TOC analyses are apparent especially during continuous monitoring more

• A possible mechanism of metabolic regulation in Gibberella fujikuroi using a mixed carbon source of glucose and corn oil inferred from analysis of the kinetics data obtained in ...

  Abstract A non‐structured model was used to study the dynamics of gibberellic acid production in a stirred tank bioreactor. Experimental data were obtained from submerged batch cultures of Gibberella fujikuroi (CDBB H‐984) grown in varying ratios of glucose‐corn oil as the carbon source. The nit more

• Effect of Selected Aldehydes Found in the Corncob Hemicellulose Hydrolysate on the Growth and Xylitol Fermentation of Candida tropicalis

  Abstract The effects of four aldehydes (furfural, 5–hydroxymethylfurfural, vanillin and syringaldehyde), which were found in the corncob hemicellulose hydrolysate, on the growth and xylitol fermentation of Candida tropicalis were investigated. The results showed that vanillin was the most toxic more

• Modeling of transient flow through a viscoelastic preparative chromatography packing

  Abstract The common method for purification of macromolecular bioproducts is preparative packed‐bed chromatography using polymer‐based, compressible, viscoelastic resins. Due to a downstream processing bottleneck, the chromatography equipment is often operated at its hydrodynamic limit. In this more
