It literally means âby way of e-mailâ which probably doesnât help either. In the âold days,â paper letters could be sent via courier, via air mail. It simply means e-mail was involved.
Taxonomy. Bacteria are members of the prokaryote group. In contrast to eukaryote cells, bacteria lack a cell nucleus and customarily have no organelles. The bacteria domain can be grouped into two major categories: (a) Eubacteria and (b) Cyanobacteria.here are approximately 50 million bacterial organisms in a single gram of typical surface soil. The worldwide bacterial biomass exceeds that of all plants and animals on Earth. However, the majority of bacteria have not yet been characterised.
Bacteria are a type of microbe, or organism so small that it can only be seen with the use of a microscope. Microbes are diverse and include organisms from each of the three domains of life: Prokaryotes (bacteria), Archaea, and Eukaryotes (including protists such as diatoms, ciliates, and dinoflagellates).
