Their article, titled “Genome Sequence of Zymomonas mobilis<\/em> subsp. mobilis<\/em> NRRL B-1960,” appears in the journal’s current issue and stems from a spring Problems of Practice (PoP) course<\/a>taught by John Gibbons<\/a>, an evolutionary genomicist and assistant professor of biology. PoP courses provide Clark undergraduates with internship-like experiences within an academic context.<\/p>\n

“For undergraduates, opportunities to play a big role in a research project are rare, which is one of the primary reasons I developed The Genome Project (BIOL 209),” Gibbons says.<\/p>\n

The first author on the paper is Katherine Chacon-Vargas<\/a>, a doctoral student in Gibbons’ lab who worked with the undergraduates, including Alexandra Chirino<\/a> ’18, Meghan Davis<\/a> ’17, Sophia Debler<\/a> ’17, Wynn Haimer<\/a> ’18 and Justin Wilbur<\/a> ’17, an incoming fifth-year master’s program in biology<\/a> student ; and fifth-year M.S. in biology students Ethan Wainblat<\/a> ’16 and Baxter Worthing<\/a> ’16, M.S. ’17. Two doctoral students at Clark also are co-authors: Xiaoli Mo<\/a> and Shu Zhao<\/a>.<\/p>\n

Each semester, Gibbons’ PoP course gives students the opportunity to achieve a first for them — and for science as a whole: piecing together the DNA blueprint of an organism with no existing reference genome.<\/p>\n

This year’s students sequenced the DNA of Zymomonas mobilis, <\/em>a bacterium isolated from spoiled cider in Scotland. They obtained the sample from the U.S. Department of Agriculture.<\/p>\n

“By far the most rewarding aspect of this course was witnessing discovery. It’s something that drives me as a scientist, and it was exciting to watch students experience this for themselves,” Gibbons says. “In one instance, three groups, using entirely different methods, independently discovered a set of genes that were unique to our isolate of Zymomonas mobilis<\/em>. The whole class was talking about TonB receptors (proteins found in the outer membranes of the bacterium) for a couple weeks after that.”<\/p>\n

Gibbons’ lab focuses on domestication of microbes like Z. mobilis<\/em>.<\/p>\n

“If you think about how dogs were domesticated from wolves, we study how microbes were domesticated,” Gibbons explains. “In the case of Zymomonas mobilis<\/em>, we know it’s been used by humans for thousands of years, but we don’t know if it’s been domesticated, and that’s what we’re trying to learn.”<\/p>\n

Z. mobilis<\/em> can lead to spoilage in cider and beer, but it also can be deployed to create alcoholic beverages such as pulque, a popular drink made in Mexico from the fermented sap of the agave plant.<\/p>\n

Even more, the microbe can be used to produce ethanol for biofuel. For that reason, the U.S. Department of Energy is interested in such research.<\/em><\/p>\n

“This bacterium has a unique biochemical pathway that allows it to produce ethanol more efficiently than yeast, which the biofuel industry is currently using,” Gibbons says.<\/p>\n

To sequence the genome for Z.<\/em> mobilis<\/em>, students gained experience in bioinformatics, collecting and analyzing large volumes of data. They wrote code in the Linux computer language and developed methodologies by piecing together analysis from several open-source algorithms, employing Clark’s High Performance Computing Cluster. They presented their results at Clark’s Academic Spree Day<\/a> this spring.<\/p>\n

“We compared all the sequenced strains of Zymomonas mobilis<\/em>, trying to find the unique genes in our particular strain, and we found there were 52 unique genes in comparison to all the other six strains,” explains Chirino, a biology major who plans to concentrate in bioinformatics. “It was fun to learn on the job. I got to see how much I like using computers; I could test myself.”<\/p>\n

Haimer — a biology major who plans to apply to Clark’s fifth-year management (M.B.A.) program<\/a>, then head to medical school — says bioinformatics is a useful skill to add to his résumé.<\/p>\n

“Bioinformatics is where this field is headed — that junction of biology and computer science,” he says. “This course was fun, and although I don’t know if bench work research is necessarily what I want to pursue for my career, I’m hoping that whatever I do will open as many doors as possible.”<\/p>\n
