Species

Whittami

Description and Significance

E. whittami was named after Thomas S. Whittam(1). He had an extensive career as a researcher during which he studied, among other bacteria, Escherichia coli. One of his biggest contributions to microbiology was an internationally accepted collection of E. coli strains. He also taught at a university and mentored numerous graduate students. Tragically, he passed away in 2008 after being diagnosed with brain cancer (2).

Genome Structure

According to the genome assembly ASM2028370v1, Escherichia whittamii has a genome size of 4.6 Mb and is 50.5 percent GC. It has between 4,359 and 4,341 genes of which 4,031 and 4,167 protein-coding (1).

Cell Structure, Metabolism and Life Cycle

Originally cultured from chicken feces, these bacteria are able to grow at 37 degrees Celsius, making them mesophiles, and under anaerobic conditions. These conditions are similar to the environment the bacteria were cultured from (Gilroy).
