A polymer is simply a large molecule (i.e. macromolecule) built up by repetitive binding together of many smaller units called
monomers. Some of the natural polymers are polysaccharides (from glucose units), proteins (from amino acids) and nucleic acids (fromnucleotide units)

Homopolymer and Copolymer Synthetic polymers derived from a single repeating monomer are known as homopolymers while those derived from two or more types of repeating monomer units is known as copolymer.

Average Molecular Mass of Polymer A polymer sample contains chains of varying lengths and thus its molecular mass is expressed as an average as defined in the following .

Professor Maureen McCann, Director of the Energy Center at Purdue University, addresses “A Roadmap for Selective Deconstruction of Lignocellulosic Biomass to Advanced Biofuels and Useful Co-Products” on February 11, 2013 as part of the Andlinger Center’s 2012-2013 Highlight Seminar Series.

ABSTRACT
Second-generation biofuels will be derived from lignocellulosic biomass using biological catalysis to use the carbon in plant cell wall polysaccharides for ethanol or other biofuels. However, this scenario is both carbon- and energy-inefficient. The major components of biomass are cellulose, hemicellulose and lignin. Biological conversion routes utilize only the polysaccharide moiety of the wall, and the presence of lignin interferes with the access of hydrolytic enzymes to the polysaccharides. Living micro-organisms, required to ferment released sugars to biofuels, utilize some sugars in their own growth and co-produce carbon dioxide. In contrast, chemical catalysis has the potential to transform biomass components directly to alkanes, aromatics, and other useful molecules with improved efficiencies. The Center for Direct Catalytic Conversion of Biomass to Biofuels (C3Bio) is a DOE-funded Energy Frontier Research Center, comprising an interdisciplinary team of plant biologists, chemists and chemical engineers. We are developing catalytic processes to enable the extraction, fractionation, and depolymerization of cellulose and hemicellulose coupled to catalytic transformation of hexoses and pentoses into hydrocarbons. Additional catalysts may cleave the ether bonds of lignin to release useful aromatic co-products or that may oxidize lignols to quinones. In a parallel approach, fast-hydropyrolysis is a relatively simple and scalable thermal conversion process. Our understanding of biomass-catalyst interactions require novel imaging and analysis platforms, such as mass spectrometry to analyze potentially complex mixtures of reaction products and transmission electron tomography to image the effects of applying catalysts to biomass and to provide data for computational modeling. By integrating biology, chemistry and chemical engineering, our data indicate how we might modify cell wall composition, or incorporate Trojan horse catalysts, to tailor biomass for physical and chemical conversion processes. We envision a road forward for directed construction and selective deconstruction of plant biomass feedstock.

BIOGRAPHY
Maureen McCann is the Director of Purdue’s Energy Center, part of the Global Sustainability Initiative in Discovery Park. She obtained her undergraduate degree in Natural Sciences from the University of Cambridge, UK, in 1987, and then a PhD in Botany at the John Innes Centre, Norwich UK, a government-funded research institute for plant and microbial sciences. She stayed at the John Innes Centre for a post-doctoral, partly funded by Unilever, and then as a project leader with her own group from 1995, funded by The Royal Society. In January 2003, she moved to Purdue University as an Associate Professor, and she is currently a Professor in the Department of Biological Sciences.

The goal of her research is to understand how the molecular machinery of the plant cell wall contributes to cell growth and specialization, and thus to the final stature and form of plants. Plant cell walls are the source of lignocellulosic biomass, an untapped and sustainable resource for biofuels production with the potential to reduce oil dependence, improve national security, and boost rural economies. She is also the Director of the Center for Direct Catalytic Conversion of Biomass to Biofuels (C3Bio), an interdisciplinary team of biologists, chemists and chemical engineers in an Energy Frontier Research Center funded by the US Department of Energy’s Office of Science.
