2008 Division O Symposia

Symposium 014/O
Monday, 6/2/2008 - 8:00 - 10:30 AM
Room 153A

Dr. Lee R. Lynd of Dartmouth College in Hanover, New Hampshire will deliver our Division O Lecture, titled "Going Beyond The Limits: Challenges In Renewable Fuels from Lignoce".

    Genomic Expression Analysis of Stress Tolerance for Ethanol and Butanol Production
    Conveners: T. W. Jeffries and J. B. Doran-Peterson

    Speakers:
  • Division O Lecture: Going Beyond The Limits: Challenges In Renewable Fuels from Lignoce
    L. R. Lynd; Dartmouth Coll., Hanover, NH
  • Utilization of Pentose-hexose Mixtures by Saccharomyces cerevisiae: Integration of Metabolic Engineering and Evolutionary Approaches
    J. Pronk; Delft Univ. of Tech., Delft, BC, NETHERLANDS
  • Expression Array Analysis of Stress Response by Saccharomyces cerevisiae

  • Development of Advanced Microbes for the Next Generation Biofuels and Chemicals
    E. M. Green; Green Biologics, Ltd, Abington, UNITED KINGDOM
      • Bioconversion of lignocellulosics is limited by the formation of inhibitors during pretreatment, the rate of cellulose saccharification, and product accumulation. Current research is attempting to overcome all of these limitations through novel bioprocessing technologies, the development of strains resistant to inhibitors, expression array analyses and genetic engineering to overcome metabolic bottlenecks. This symposium will focus on the fundamental physiological limits and responses of microbes to ethanol, butanol and other potential inhibitors encountered in bioconversion of lignocellulosics and the physiological constraints of the microbes carrying out the conversions.

      Upon completion of this session, participants should be able to:
      • Identify critical barriers to the microbial production of ethanol from lignocellulosics.
      • Identify possible technical approaches to their solution.
      • Better understand the physiology and biochemistry behind ethanol and butanol inhibition.

Symposium 118/O

    U. Singh; Stanford Univ. Sch. of Med., Stanford, CA

      • A number of biological processes are intimately connected to an organism's developmental program. Pathogenicity and survivability of both plant and mammalian pathogens is often dependent on the invading microbe's ability to undergo differentiation in response to host environmental factors. This is also true of processes such as production of toxins and secondary metabolites in both bacteria and fungi. In many cases the signaling pathways and transcriptional regulatory networks involved in cellular morphogenesis, secondary metabolism and pathogenesis are very complex and the cross-talk between these pathways is often not well understood. This session will provide information on developmental regulatory factors that control such diverse biological processes as secondary metabolism, pathogenesis, and cellular morphogenesis in organisms of medical, industrial, and agricultural importance. The information presented should be of interest to those involved in biotechnology, general and medical microbiology and molecular and biochemical regulation of cellular morphogenesis as it impacts a wide range of biological processes.

      Upon completion of this session, participants should be able to:
      • Describe a number of regulatory factors involved in cellular development and how these factors impact important biological processes.
      • Develop experimental approaches to study the role and regulation of novel developmental and physiological factors in response to environmental stimuli.
      • Cite examples of how elucidation of molecular mechanisms controlling developmental processes can provide insights into an organism's pathogenicity/virulence, developmental program, survivability, and metabolite production.
