Organisation or Individual Expertise:
Prof. Gary Walsh is Chair of Industrial Biotechnology within the department of Chemical and Environmental Sciences at the University of Limerick, Ireland. His primary research focus is in the areas of (a) second generation bioethanol production from lignocellulosics and (b) cleaner, greener processing (both areas described below). He has participated in research grant proposal applications which have successfully secured €3.1 million in funding, of which his personal share is €2.0 million. His research collaborations span both academic and industrial partners. He has supervised/continues to supervise 22 researchers (14 postgraduate students and 8 post-doctoral research scientists). His 200+ publications include 105 ‘class 1’ publications (9 authored books, 2 edited books, 17 book chapters and 77 journal articles – h-index, 17). He has also presented his work at 60 international conferences. Research interest, Area 1: Biofuel/biorefinery Context & lay summary The development of renewable sources of liquid fuels as an alternative to fossil fuels is receiving increasing global attention due environmental, economic and energy security concerns. The production of bioethanol from cellulose-based raw materials (e.g. grass, straw & wood) is at the forefront of this technology, but a major stumbling block is how to effectively degrade the cellulose to its glucose building blocks (the glucose is then fermented to ethanol, basically by brewing technology). A major on-going focus of my research group is the identification and use of enzymes (proteins that speed up chemical reactions) derived from thermoacidophilic bacteria (bugs that grow best in boiling acid) to more efficiently achieve cellulose degradation (a process that currently usually entails the use of boiling acid). These enzymes are also academically interesting because they work best under such extreme conditions. Technical description/recent and on-going projects Studies of the fundamental properties and industrial application, with particular emphasis upon biorefinery, of secretome (lignocellulosic) enzymes from thermoacidophilic microorganisms. Our current lead enzyme is a cellulase displaying optimal activity at 100oC and pH 3.5, and which is stable under these conditions for several hours. Project 1: Development of an alternative processing technology, using thermoacidophilic enzymes, for the production of second-generation bioethanol (€75,000) Project 2: Application of novel enzymes derived from thermoacidophiles to second-generation biofuel Production (€355,000) Sample publications Publication on hold until any associated intellectual property is secured. Research interest, Area 2: Cleaner, greener processing Context & lay summary This area of my lab-based research work focuses upon decreasing the environmental impact of biotechnological and related industrial processes. To date our focus has been upon the dairy processing industry and on the pharmaceutical manufacturing, but the same principles could be applied to many other industries/processes. Some projects are undertaken in cooperation with other UL research groups. Recent and on-going projects Project 1: Minimisation of hazardous waste generated by CIP operations in the dairy processing industry (€171,000) Project 2: The potential of whey in industrial fermentations and broader characterization of agri-processing waste (€196,000). Project 3: An environmental analysis of biopharmaceutical manufacturing in recombinant E. coli, with a viewto waste minimization of Phosphorous and Nitrogen content in waste streams generated (€ 40,000) Project 4: Environmental issues relating to the manufacture of antisense-based products of pharmaceutical biotechnology (€85,000) Sample publications Boyce, A. and Walsh, G. (2012) Identification of fungal proteases potentially suitable for environmentally friendly cleaning-in-place in the dairy industry. Chemosphere, 88, 211-218 Boyce, A., Piterina, A. and Walsh, G. (2010) Assessment of the potential suitability of selected commercially available enzymes for cleaning in place (CIP) in the dairy industry. Biofouling, 26 (7), 837-850. Cliffe, F.
