SLSC 398 Lecture Notes - Lecture 3: Facultative Anaerobic Organism, Aerobic Organism, Obligate Aerobe
Document Summary
A strain is once it is isolated in the lab. Microenvironment - always impacted by changes in concentration so the bacterial environment is changing. Depending on how much aeration you have the bacteria has to change to the soil air gas concentrations. Niche - focused on the biological component of the strain. It describes the physical and chemical parameter for the organisms to be active. The exact place of the organism, the replicate it in the lab. Changes in the season, moisture content. ph: a ects membrane transport, enzyme activity, cell membrane electrical gradient. If the ph is wrong you will have the wrong number of protons in environment. Out of the various measurements in the soil the ph is the most important one to determine the bacteria in the soil. Salt concentration: determines the concentration of ions in the soil solution the cell will not be active under di erent conditions.
