Names of microorganisms or groups of microorganisms that may appear in the final
exam of BIO 2EE3
Agaricus bisporus –edible bacidiomycete mushroom
Agrobacterium tumefaciens – bacteria that can infect plants with its Ti plasmid
Bacillus – endospore forming, aerobic rods. Anthracis and subtilis for example.
Bacteroidetes – obligate anaerobes that digest complex plant carbs in our gut; most
common organism in human feces
Candida – a genus of yeast. Some species such as C. albicans are found in the gut.
Chlamydia – C. trachomatis causes STD while C. pneumoniae causes pneumonia;
reticulate body is more harmful than elemental body
Chlamydomonas – unicellular flagellate green algae
Clostridium – fermicutes/actinobacteria botulinum and tetani for example
Cyanobacterium – phylum of photosynthesizing bacteria
Deinococcus radioduran – even though it’s not thermophilic, it is classified as a deep
branching thermophile because of its 16 S rRNA sequence. Resistant to radiation.
Escherichia coli – Gamma proteobacteria; model gram negative bacteria
Halobacterium – Euryarchaeota that lives in hypersaline environments. Rhodopsin
produces ATP when struck by light; rhodopsin 1 absorbs blue light while rhodopsin 2
absorbs red light. Blue light = harmful, swim away; Red light = good, swim toward.
Helicobacter – Epsilon Proteobacteria that causes stomach ulcers; converts urea into
ammonium to withstand low stomach pH
Human Immunodeficiency Virus – retroviral lentivirus (slow incubation) with 2
copies of single stranded DNA; attaches to CD4 surface protein
