Bacteria as “ink” for writing the initials of names on agar
Mementos encapsulate memories and serve as triggers for their recollections. By using a purple pigment producing bacterium as “ink” for writing on agar, a picture memento depicting the initials of students’ names was created to help them recollect, in future, the strong friendships that they fostered during their final year research projects. Besides the fun activity of “Bacterial calligraphy”, the surface patterning technique can also serve as a simple and relatively low cost tool for testing the feasibility of research ideas; for example, depositing cells in both straight and curvilinear lines on planar substrates may find use in understanding possible interactions between different microorganism species. A synopsis of the work and a structured abstract can be found in the accompanying PDF file, while the original article, “Bacterial Calligraphy: A Memento for Undergraduate Research Students”, is available in the Journal of Microbiology and Biology Education, Vol. 13, No. 2, pp. 172-174 as an open access article, URL http://www.asmscience.org/content/journal/jmbe/10.1128/jmbe.v13i2.414 .
