Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...
Depleting oil reserves have encouraged the development of technologies to harness the natural resources to sustain the energy needs. Renewable lignocellulosic biomasses have been focus of many studies but advances in the purification and recovering of the products from the product medium has been...
Production of bioethanol from lignocellulosic biomass requires pretreatment of the biomass to hydrolyze hemicellulose, separate lignin and reduce cellulose crystallinity. During the pretreatment by dilute acid hydrolysis, several grams of acetic acid per liter of hydrolysate is generated. Acetic...
A better understanding of the complex interplay between cell population dynamics and mass transport is necessary for overcoming the barriers that have slowed down the development of bioartificial tissues. In a recent publication [1], we presented the development of a multi-scale computational model...
Alternative energy and climate change are among the largest concerns facing scientists and engineers at the start of the twenty-first century. The focus of this research is the design of a system that can efficiently capture atmospheric carbon dioxide and reduce it to CO, a precursor for fuel...
Please Note : Advances in Bioprocessing -- Spring Meeting 2009 includes the following recorded presentations: · Biofuel and Biochemical Productions from Mixed Sugars Derived from Lignocellulosic Biomass by the RITE Bioprocess · One Step Cellulosic Ethanol Production · A Framework to Suggest Enzyme...
Even with the use of costly corrosion-resistant alloys, metal contamination continues to occur in the biologics industry, thus reducing product yield and activity. Fluoropolymers are emerging as a viable solution to this problem.
This article presents the challenges that an engineer might encounter when designing or scaling up bioprocesses and offers practical solutions, including those cited in literature.
The use of complex living organisms, process variation, and lack of real-time measurements of key parameters are some of the challenges involved in automating a bioprocess. This article explains an indirect approach to monitoring and controlling a...
These experimental and modeling techniques enable the rapid, cost-effective design and scale-up of biopharmaceutical manufacturing in an integrated fashion.
Once we have grasped some essentials of this riotous, but surprisingly well ordered world, we shall find our transport phenomena background to have real utility.
