From Biochemical Engineering to Synthetic Biology: A Short History of Engineering Impacts on Biotechnology

SBE Webinar

Sep 27, 2012

Harvey Blanch

This webinar will focus on how biochemical engineering developed in response to the need for large-scale production of antibiotics in the 1940s and 50s, even though fermentation provided a route to many industrial organic chemicals prior to their production from petroleum.

Improving Corn Stover Reactivity In Low Severity Pretreatment Through Deacetylation and Disc-Refining

Oct 18, 2011

Xiaowen Chen

The current “state-of-art” dilute acid pretreatment to produce bio-ethanol from corn stover requires severe conditions to overcome biomass recalcitrance, which, in turn, offers 70~80% xylose monomer yield and 5~7% furfural yield. However, high acid loadings and high reaction temperatures harm the...

Insights Into Lactate Metabolism Through Multivariate Analysis of Cell Culture Bioprocess Data

Oct 18, 2011

Huong Le

Multivariate data analysis has recently emerged as a critical tool to gain fundamental understandings of process characteristics, and thus assisting the search for possible intervention means to improve process performance. The time dynamics of 150 process parameters acquired from 243 production...

QbD for Generic MR Drug Products

Oct 18, 2011

Yue (Helen) Teng

The Office of Generic Drugs ensures the therapeutic equivalence and quality of generic drug products. This is based principally upon a regulatory paradigm that requires pharmaceutically equivalent drug products containing the same active ingredient, dosage form, and strength (among other things),...

Ab-Initio Study of Glycerol Dehydration Mechanisms with Explicit Solvent Treatment

Oct 18, 2011

Tim Courtney

Glycerol produced as a waste product in biodiesel production has interesting potential as a low-cost biomass-derived feedstock for chemical processing. A process of current academic and commercial interest is the acid-catalyzed dehydration of glycerol to acrolein, a valuable platform chemical. Such...

Membrane Filtration of Lignocellulosic Hydrolyzates: Comparison of Crossflow and Dead-End Microfiltration

Oct 18, 2011

Bhavin Bhayani

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...

Synthesis of Green Diesel Fuel From Fatty Acid Feedstocks Via Electrochemical Hofer-Moest Decarboxylation

Oct 18, 2011

Cody Wagner

Production of biodiesel by esterification or transesterification of long-chain fatty acids is a well known process, but the fuel product has characteristics making it not fully compatible with petroleum diesel engines. A better option is to convert fatty acid molecules to hydrocarbons by removing...

Transferring Monitoring Models Between Different Scales Through Multivariate Statistical Techniques

Oct 18, 2011

Emanuele Tomba

The challenge of transferring a process monitoring model across different scales is a different problem than the one addressed in previous studies that have focused on transferring operating procedures looking to produce the same grade of product [1, 2, 3, 4]. In the development of a new...

Integration of a Membrane Based Extraction Process Into a Lignocellulosic Biorefinery

Oct 18, 2011

Ranil Wickramasinghe

In the future, it is anticipated that multi-product biorefineries will be used to convert lignocellulosic biomass to fuels and chemicals, in which, it may be possible to use membrane-based separations to recover fuels and various products and to improve energy efficiency. To biochemically convert...

An Integrated Lipid-Based Platform for “Drop-In” Fuel Biorefinery

Oct 18, 2011

Shulin Chen

A major challenge in developing biorefinery is that the availability of biomass often limits the scale of the plant thus the feasibility of an operation. We proposed an integrated lipid-based platform as one technical option. According to this concept, different biomass resources will be first...

CMC Reviewer Expectations for ANDAs Using QbD Approaches

Oct 18, 2011

Robert L. Iser

There has been an increase in science and risk-based approaches under the Quality by Design paradigm in new drug submissions to the FDA. There are particular challenges for generic drug manufacturers with respect to using QbD approaches, especially with more complex dosage forms, such as modified...

Acetic Acid Removal From the Hydrolysate Using Reactive Extraction In a Membrane Extractor/Reactor

Oct 18, 2011

Rahul Patil

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...

Enzymatic Hydrolysis of Pulp Dissolved In N Methyl Morpholine Oxide (NMMO) and Ionic Liquids

Oct 17, 2011

Subramanian Ramakrishnan

The first step in the conversion process of biomass to biofuels or hydrogen lies in picking an environmentally friendly solvent which is capable of breaking up the crystalline microstructure of cellulose. Once the cellulose is in suspension, enzymes (cellulases) are added to the reactor to...
