P-20 Characterization Of Cgx Tautomerase And Mutants With Acetylenecarboxylic Acid, Daniel Chi, Karen Draths, Amaya Sirinimal

Celebration of Research and Creative Scholarship

In the production of commodity chemicals through microbial synthesis, the use of renewable sugars as a raw material is increasingly common. However, this generates competition between its use in the chemical industry and the food industry. Therefore, developing alternative biosynthetic pathways involving other renewable feedstocks to replace starch-derived feedstocks is crucial. CgX, a tautomerase native to Corynebacterium glutamicum, catalyzes the hydration and subsequent decarboxylation of acetylenecarboxylic acid (ACA), a compound that can be produced from methane gas and carbon dioxide, both abundant greenhouse gases. The products formed from the CgX (wild-type)-catalyzed reaction of ACA results in a mixture of …

The Cavan Burren is a plantation forest within the Marble Arch Caves UNESCO Global Geopark overlay along the Republic of Ireland and Northern Ireland border. The exposure of Cavan Burren’s "relict landscape" resulted from a 2012 partial clear fell. Our multidisciplinary team of researchers in architecture, technology, ecology, fine arts, and archaeology investigated domestic architecture reflected in three stone configurations: circular/semicircular sites, rectangular sites, and tomb structures. We also investigated human action on pedestal boulders (PBs), which had been modified by sculpting, splitting, and cutting away. Our first goal was to show human action on structures by using three-dimensional (3D) …


P-29 Diversity And Species Turnover Of Late Cenozoic Ground Squirrels In The Meade Basin, Ks, H. Thomas Goodwin Oct 2015

P-29 Diversity And Species Turnover Of Late Cenozoic Ground Squirrels In The Meade Basin, Ks, H. Thomas Goodwin

Celebration of Research and Creative Scholarship

The Meade Basin of southwestern Kansas preserves one of the richest fossil sequences from the late Cenozoic of North America. An ongoing study has documented a rich record of fossils, especially rodents; established episodes of especially rapid species turnover (when species appear or disappear from the local record); and has attempted to relate these processes to environmental change inferred from stable isotope and other proxies for ancient climate. Here, I report on fossil squirrels from the record. At least 7 genera and 13 species are present in the composite record. Species turnover occurs throughout the record, but an especially high …
