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.

Society for Biological Engineering (SBE)

SBE is a global technological community that promotes the integration of engineering with biology and realize its benefits through bioprocessing, biomedical, and biomolecular applications. SBE provides opportunities for interaction of engineers and scientists, develops products and services bring value to the broad biological engineering community, and infuses awareness of biological engineering among all functions and activities of AIChE.

Food, Pharmaceutical & Bioengineering Division (FP & BE)

The FP&BE division coordinates AIChE's activities in the fields of food, pharmaceuticals, and bioengineering.

Forest Bioproducts Division (FBP)

The Forest Bioproducts Division promotes knowledge sharing and networking on topics dealing with products obtained from forest resources and other lignocellulosic materials.

Rule of Thumb for Design of Catalytic Pyrolysis of Biomass In Bubbling Fluid Bed Reactor

Oct 16, 2011

Foster Agblevor

The production of stable biomass pyrolysis depends strongly on both reactor design and the effective design of a condensation train to collect the pyrolysis products. There are several challenges in the design of the pyrolysis system including solids feeding, char separation from the pyrolysis...

Low Temperature Gasification of Impregnated Biomass Feedstock

Oct 16, 2011

Foster Agblevor

Hybrid poplar biomass feedstocks were impregnated with catalysts and gasified at three different temperatures in a bubbling fluidized bed reactor. The impregnated biomass were gasified in a nitrogen atmosphere at 400 o C, 600 o C, and 800 o C. The gas yield increased with increasing temperature as...

Catalytic Cracking of Oak Pyrolytic Vapors Via Bench-Scale In-Situ Fixed-Bed Catalysis

Oct 16, 2011

David J. Mihalcik

Pyrolysis oils derived from lignocellulosic feedstocks by way of fast pyrolysis offer the possibility of a distinct alternative to the use of petroleum-based fuels. However, an inherent drawback associated with pyrolysis oil its high oxygen content which is due to the nature of the lignocellulosic...

Rule of Thumb for Reactor Design and Process Conditions for Supercritical Water Gasification of Wet Biomass

Oct 16, 2011

Yukihiko Matsumura

The Rule of thumb for reactor design and process conditions for supercritical water gasification of wet biomass is introduced. The important aspects includes heat transfer and heating rate, reaction rate, plugging, gas composition, inorganic element behavior, and heat of reaction. The know-hows...

Biomass Pyrolysis and Gasification: Engineering Rules of Thumb

Oct 16, 2011

Michael J. Antal

In this presentation I review important findings recorded in the archival literature concerning the thermodynamics, kinetics, mechanisms, and catalysis of biomass pyrolysis and gasification that serve as rules of thumb for reactor design.

OPTIMIZING IN-VITRO FERTILIZATION TREATMENT: A Pedagogical Case Study of Random Phenomena Analysis

Oct 16, 2011

Babatunde A. Ogunnaike

Engineering practice has always required involvement in the acquisition, analysis, interpretation and exploitation of data in one form or another, so that the “well-educated” engineer ought to be truly conversant with how to handle data. This is even more so today, with many engineers now working...

Lignin Unlocking Process Led by Termites for Efficient Carbohydrate Utilization

Oct 16, 2011

Jing Ke

Wood-feeding termites are highly effective in deconstruction of wood cell wall structure for efficient utilization of cellulose and hemicelluloses. One of the key factors for its effectual cell wall disintegration is the lignin structure modification for de-protection. In this study, we provide...

Rules of Thumb for Reactor Design and Process Conditions for Thermochemical Treatment of Chromated Copper Arsenate (CCA) Treated Wood Waste

Oct 16, 2011

Lieve M. Helsen

Lab-scale pyrolysis experiments have been performed to gain insight in the mechanisms influencing the metal behavior during carbonization of chromated copper arsenate (CCA) treated wood chips. To this end a fixed bed low temperature pyrolysis reactor and a thermogravimetric (TG) analyser have been...

Reforming of Residual Tars and Oils From Biomass Gasification

Oct 16, 2011

Lyman Frost

One of the barriers to wider use of many kinds of biomass is the fact that they generate refractory tars and oils when gasified. These compounds cause difficulty when they are passed to downstream components in the system by causing plugging and drop in performance. The compounds can be condensed...

Dr. Langer discusses the involvement of engineering in health care, from the discovery of the first angiogenesis inhibitors to the development of controlled drug delivery systems and the foundation of tissue engineering.

Using Synthetic Biology to Engineer Syntrophic Microbial Communities for Bioprocess Applications

Nov 7, 2010

Ross P. Carlson

A combination of synthetic biology and in silico network analysis was used to construct artificial microbial consortia comprised of engineered Escherichia coli strains. The design was based on biomimicry of key ecological roles found in stable, naturally occurring microbial consortia. In silico...

A Microrna Based Synthetic Network as Stable Expression Unit in Mammalian Cells

Nov 7, 2010

Leonidas Bleris

The utility and scalability of complex synthetic gene networks is hampered by fluctuations in stoichiometry between different gene products in individual cells. A critical contribution to the fluctuations arises from variation in the basic transcription efficiency of a gene product that in turn is...

Directed Evolution of Quorum-Sensing Dependent Transcriptional Repressors for Programmed Intercellular Communication

Nov 7, 2010

Cynthia H. Collins

One of the key challenges in the field of synthetic biology is to engineer not only single cells but also communities of cells that exhibit coordinated, population level behaviors. Synthetic biologists have employed components from acyl-homoserine lactone (AHL)-based quorum-sensing (QS) systems in...
