Epulopiscium spp. are some of the largest known bacteria. Individuals can reach lengths in excess of 0.6 mm; large enough to be seen with the unaided eye. Another unusual feature of this group of bacteria is the manner in which they reproduce. While most bacteria simply divide into two equivalent daughter cells, an Epulopiscium cell can produce multiple offspring internally. Research in the Angert lab focuses on characterizing cellular modifications that support large cell size in a bacterium. We are also working toward identifying the molecular mechanisms involved in internal offspring formation and development. And finally, we are interested in determining how reproductive strategy impacts the symbiotic relationship of intestinal bacteria and their vertebrate host.

Understanding the role of microorganisms in natural environments is one of the greatest challenges facing microbiologists. My courses are aimed at introducing undergraduate and graduate students to current approaches to assess microbial community diversity and microbial activity in a variety of ecosystems. In addition, activities are designed to enhance and refine communication skills and introduce students to current scientific literature.

Epulopiscium provides an exciting model for conveying basic concepts of the bacterial cell. These cells are visually appealing and can be seen with the unaided eye. The fact that Epulopiscium spp. are so large, but not pathogenic, makes them a good representative of the microbial world not only for biology students but for the general public as well. To facilitate information flow, a website featuring Epulopiscium has been established. Students at all levels are involved in the development and maintenance of the site. This project instills in students the responsibility of all researchers to disseminate information to the public and it will enhance the students’ ability to communicate their work and its significance to a diverse audience. In addition, we participate in a number of outreach programs to share our enthusiasm and ideas about biology to K-12 students and their teachers.
