An important aspect of teaching biology is to expose students to the concept of biodiversity. For this purpose, bacteria are excellent examples. Prokaryotes were the first inhabitants on Earth, surviving and even thriving under very harsh conditions as new species continuously evolved. In fact, it is believed that there are more than 5 x 10\textasciicircum30 prokaryotes living on Earth today (Whitman et al., 1998). Our current knowledge of these tiny organisms is very limited, and less than 1% of all bacterial species have been described (Horner-Devine et al., 2004). However, the prominent roles bacteria play in nature are not easy to overlook: Their functions range from providing essential nutrients to plants through nitrogen-fixation (such as for Rhizobium leguminosarum) to enhancement of nutrient absorption in animal intestines (such as for Escherichia coli). As a result, identifying unknown species of bacteria and extending our understanding of known ones are important tasks for 21st Century scientists.
