<p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">A research team at Konkuk University in Seoul, South Korea developed a new alcoholic fermentation method using an electrospray cell patterning technology. <br /></span><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><br />The electrospray is a generation method of tiny droplets by exposing liquid solutions to a high voltage electric field. John B. Fenn at Yale University, US (Nobel laureate in chemistry 2002) electrosprayed biological molecules and developed the electrospray mass spectrometry. <br /></span><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><br />Konkuk University team (Principal Investigator: Prof. Byung Uk Lee) succeeded in electrospraying viable bacterial cells in 2008 (Journal of Aerosol Science, European Aerosol Assembly) and developed an electrospray cell patterning method at cellular resolution using vibrational electrical field in 2010 and 2015 (Analytical Chemistry, Journal of Microbiology and Biotechnology).</span><span style="font-size: 11pt; font-family: 굴림;"><br /></span><span style="font-size: 11pt; font-family: 굴림;"><br /><img style="margin-left: auto; display: block; margin-right: auto;" alt="" src="ArticleFile.do?id=11777967" width="513" height="342" /></span><span style="font-size: 11pt; font-family: 굴림;"><br /></span><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">In 2019, they electrosprayed yeast (<em>Saccharomyces cerevisiae</em>) cells and discovered that yeast cells patterned by this electrospraying method could conduct alcoholic fermentation performance with high speed rates.</span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Prof. Byung Uk Lee (PI, bioaerosol researcher) said that this finding shows a fundamental method for viable single cell analysis as well as alcoholic fermentation applications. He also mentioned that the 2008 discovery of electrospraying viable cells approaches practical applications.</span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">This experimental results were published on December 9, 2019 at <em>Scientific Reports</em> (Nature Research) and are available freely at the following website of the Nature Research. </span><br /><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><a href="https://www.nature.com/articles/s41598-019-55225-4"><u>https://whttps://www.nature.com/articles/s41598-019-55225-4ww.nature.com/articles/s41598-019-55225-4</u></a></span></p> <p><a href="https://www.nature.com/articles/s41598-019-55225-4"><span style="font-size: 11pt; font-family: 굴림;"></span> </a><span style="font-size: 11pt; font-family: 굴림;"><br /><br /><img style="margin-left: auto; display: block; margin-right: auto;" alt="" src="ArticleFile.do?id=11777964" width="496" height="774" /></span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Microscopic photographs of the yeast patterns produced by electrospraying with vibrational electric field.
