Continuing with cultural activities, the following items constitute
"John L's Bacteriology Pages" which are also indexed here
with additional commentary.
At least the Selected General Microbiology Topics will remain on the web in perpetuity – freely-accessible as always. Even though the Bacteriology 102 Site and the Microbiology 102 Site may be technically "archived," the reference material dealing with subject matter which is found in each site is updated as necessary. |
Selected General Microbiology Topics: Most are probably applicable to any general microbiology lab course. General index page is here.
- Nutrition and Cultivation of Bacteria
- General Overview of Catabolism
- Review of the Cycles of Elements
- Proper Usage of Terms and Scientific Names
- Flow Charts, Tables and Dichotomous Keys
- Selected Aseptic Technique Procedures (with movies!)
- Dilution Theory:

"A differential medium can be formulated ('programmed') to exploit the characteristics of one or more particular physiological types of organisms, and the net result from competing alkaline and acidic reactions can assist greatly in the detection and differentiation of such organisms."
(A field of classical microbiology that is still fully viable and exploitable. This thought continues here.) |

My long-promised page on "ET Agar" for the isolation of Edwardsiella tarda is finally on the web here. This is essentially a distillation of various poster sessions (and their handouts) on the subject which were given publicly in the 1990s. |

"Rather than (or in addition to) using 'oxygen relationships' as descriptive terms – however they may be determined or defined – we can characterize and classify bacteria more consistently and comprehensively by applying the method(s) of energy generation of which an organism is capable:
- aerobic respiration
- anaerobic respiration
- fermentation
- anoxygenic phototrophy
- oxygenic phototrophy"
(One of the foundations of microbiology examined in Bacteriology 102. More about this is here.)

True or False: To isolate a certain kind of organism from a natural source, we always try to duplicate the original habitat of the organisms in the laboratory as much as possible.
False! This would not speed up the process by which you are attempting to get your isolated pure culture. Rather than waste time doing this, proceed with selective isolation procedures from your sample without undue delay. (More about this concept is covered here.) |
