Patent number: 8765408Abstract: The present invention provides a bacterium having a genome that is genetically engineered to be smaller than the genome of its native parent strain. A bacterium with a smaller genome can produce a commercial product more efficiently. The present invention also provides methods for deleting genes and other DNA sequences from a bacterial genome. The methods provide precise deletions and seldom introduces mutations to the genomic DNA sequences around the deletion sites. Thus, the methods can be used to generate a series of deletions in a bacterium without increasing the possibility of undesired homologous recombination within the genome. In addition, some of the methods provided by the present invention can also be used for replacing a region of a bacterial genome with a desired DNA sequence.Type: GrantFiled: February 1, 2012Date of Patent: July 1, 2014Assignee: Wisconsin Alumni Research FoundationInventors: Frederick R. Blattner, John W. Campbell, David Frisch, Guy Plunkett, III, Gyorgy Posfai

Publication number: 20130027913Abstract: A makeup mirror having a light source configured to have output that not only enhances the visibility of objects as they are reflected by the mirror, but also optimizes visual acuity of the reflected image as captured by the human eye. In some cases, the makeup mirror allows for separate adjustment of the mirror and the light source, which, in combination with the light source, enables the reflected objects to be lit in uniform manner and for optimized human visual acuity while allowing for areas of the objects to be examined in detail as desired.Type: ApplicationFiled: July 29, 2011Publication date: January 31, 2013Applicant: OTTLITE TECHNOLOGIES, INC.Inventors: David Frisch, Kelly O'Brien Martelli, Kelly Shea Kuethe
