Michelle Waltonhttps://bios.inl.gov/Lists/Researcher/DisplayOverrideForm.aspx?ID=171Michelle WaltonMichelle R. Walton has more than 26 years of laboratory experience in environmental microbiology. After graduating from Idaho State University in 1989 with a bachelor’s degree in microbiology and a minor in chemistry she served an internship with Associated Western Universities in the Biotechnology Unit at INL. She was hired at INL in 1990. She designed and implemented experiments using microorganisms for bioremediation technologies, conducted research on the use of gas phase bioreactors for the biodegradation of volatile organic compounds and combustion gases using bacteria grown in the gas phase which led to an R&D100 award. As a senior scientist for Lockheed Idaho Technologies Co she performed experiments on the biodegradation of other volatile organics such as α-pinene, methanol, and carbon tetrachloride. Since November 1996 she has been a principal scientist (SE003 Scientist) at the Idaho National Laboratory. Her expertise includes the isolation and cultivation of microbes—including mesophilic and thermophilic acidophiles (such as Alicyclobacillus), anaerobes, bacteria, fungi, archaea, and algae. She has experience in the use of molecular techniques to monitor microbial populations, and experience using enzyme assays to determine enzyme activity on various carbohydrate substrates. The last few years she has worked on chemical pre-treatment and enzymatic hydrolysis of biomass. She also has experience working in the laboratory under BSL-2 (biosafety level 2) guidelines.<div class="ExternalClass1BE9F8EEAD0A4FC4A6254DEE11487BCA"><p>​B.S., Microbiology - Idaho State University</p></div><div class="ExternalClassE8E723457F2941BB90AA1F6FE992DDDB"><div>Fox, SL, MR Walton. 2016.  Performance Assessment of Select Organisms.  External Report.  STI ID:  INL/LTD-1637738.</div><div> </div><div><br>Fox, SL, MR Walton. 2014.  Screening Thermoacidophilic Organisms.  External Report.  STI ID:  INL/EXT-14-33722.</div></div><div class="ExternalClassE8E723457F2941BB90AA1F6FE992DDDB"> </div><div class="ExternalClassE8E723457F2941BB90AA1F6FE992DDDB"><div><br>Fox, SL, MR Walton. 2013.  Characterizing Thermoacidophilic Bacteria.  External Report.  STI ID:  INL/LTC-13-30339.</div><div> </div><div> </div><div>Lee, BD, WA Apel, J Aston, MR Walton, R Carlson.  2011.  Potential for Production of Metabolites by Alicyclobacillus acidocaldarius.  SIM 2011 Annual Meeting.  STI ID:  INL/CON-11-22122.</div><div><br> </div><div>Lee, BD,  WA Apel, and MR Walton.  2006.  Whitings as a Potential Mechanism for Controlling Atmospheric Carbon Dioxide Concentrations – Final Project Report.  OSTI ID:  911640.</div><div><br> </div><div>Lee, BD,  WA Apel, and MR Walton.  2006.   Calcium carbonate formation by Synechococcus sp. strain PCC 8806 and Synechococcus sp. strain PCC 8807.  Bioresource Technology.  97(18):  2427-2434.</div><div><br> </div><div>Lee BD, MR Walton, and JL Megio.  2005.  Biological and chemical interactions with U(VI) during anaerobic enrichment in the presence of iron oxide coated quartz .  Water Research.  39(18):   4363-4374.</div><div><br> </div><div>Lee, B.
