Patent number: 10865370Abstract: Energy efficiency is improved in a grain alcohol production plant (60) by capturing heat energy that otherwise would be lost to the environment when stillage evaporator last effect vapors (22) are condensed to recycle their water content. The low temperature/pressure heat energy of these vapors is efficiently recovered and reused by placing the vapors in direct physical contact (301, 402) with a working fluid (38) to form heated working fluid (54, 66), then using the heated working fluid directly in a process of the plant. In an embodiment, cook water used for the plant fermentation process is preheated by direct contact with stillage evaporator overhead vapor via one or more direct contact heat exchangers (301, 401) and/or a thermocompressor (402).Type: GrantFiled: March 14, 2019Date of Patent: December 15, 2020Assignee: Bioleap, Inc.Inventors: James Knight, Jr., Olan Wayne Mitchell

Patent number: 10865413Abstract: The present disclosure provides oligomeric compounds comprising at least one ?-?-constrained nucleic acid as provided herein. More particularly, the ?-?-constrained nucleic acid provided herein comprise an optionally modified nucleoside with a phosphorus containing constrained internucleoside linkage such as for example a cyclic phosphate internucleoside linkage. The ?-?-constrained nucleic acid provided herein are expected to be useful for enhancing one or more properties of oligomeric compounds they are incorporated into such as for example nuclease resistance. In certain embodiments, the oligomeric compounds provided herein hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.Type: GrantFiled: January 4, 2019Date of Patent: December 15, 2020Assignee: Ionis Pharmaceuticals, Inc.Inventors: Michael Oestergaard, Eric E. Swayze, Punit P. Seth

Patent number: 10865416Abstract: The present invention is in the field of recombinant biotechnology, in particular in the field of protein expression. The invention generally relates to a method of expressing a protein of interest (POI) from a host cell. The invention relates particularly to improving a host cell's capacity to express and/or secrete a protein of interest and use of the host cell for protein expression. The invention also relates to cell culture technology, and more specifically to culturing cells to produce desired molecules for medical purposes or food products.Type: GrantFiled: April 16, 2015Date of Patent: December 15, 2020Assignees: Boehringer Ingelheim RCV GmbH & Co KG, Vaitdogen GmbH, Lonza Ltd.Inventors: Brigitte Gasser, Diethard Mattanovich, Markus Buchetics

Patent number: 10865417Abstract: Provided are compositions and methods for compound discovery. Modified yeast that have their endogenous yeast shikimate pathway disrupted or deleted, and replaced with homologous pathway genes from one or more distinct organisms, are provided and used in assays of test agents. The homologous pathway genes are designed to supplement the disrupted or deleted shikimate pathway genes. The assays are designed to identify whether or not the test agents can interfere with the function of enzymes in the shikimate pathway from organisms that are distinct from the yeast avatar hosts. In embodiments, the disruption/deletion of the yeast endogenous shikimate pathway results in the yeast being incapable of producing chorismic acid.Type: GrantFiled: April 4, 2019Date of Patent: December 15, 2020Assignees: New York University, Neochromosome Inc., The Johns Hopkins UniversityInventors: Jef Boeke, Leslie Mitchell, Joe De Angelo, Joel S. Bader

Patent number: 10865420Abstract: The subject invention concerns materials and methods for increasing and/or improving photosynthetic efficiency in plants, and in particular, C3 plants. In particular, the subject invention provides for means to increase the number of bundle sheath (BS) cells in plants, to improve the efficiency of photosynthesis in BS cells, and to increase channels between BS and mesophyll (M) cells. In one embodiment, a method of the invention concerns altering the expression level or pattern of one or more of SHR, SCR, and/or SCL23 in a plant. The subject invention also pertains to genetically modified plants, and in particular, C3 plants, that exhibit increased expression of one or more of SHR, SCR, and/or SCL23. Transformed and transgenic plants are contemplated within the scope of the invention.Type: GrantFiled: June 11, 2014Date of Patent: December 15, 2020Assignee: FLORIDA STATE UNIVERSITY RESEARCH FOUNDATION, INC.Inventors: Hongchang Cui, Danyu Kong, Yueling Hao
