Study Notes
Bacteria Classification
- Aerobic bacteria require oxygen for growth.
- Anaerobic bacteria would die in the presence of oxygen.
- Mesophilic bacteria grow well at temperatures between 20-40°C.
- Halophilic bacteria require 3% NaCl or higher for growth.
- Non-halophilic bacteria prefer low salt concentrations below 3%.
Bacteria Classification Matchups
- Psychrophilic bacteria: grow at temperatures below 20°C.
- Mesophilic bacteria: grow at temperatures between 20-40°C.
- Thermophilic bacteria: grow at temperatures above 40°C.
- Halophilic bacteria: require 3% NaCl or higher for growth.
- Non-halophilic bacteria: prefer low salt concentrations below 3%.
- Acidophilic bacteria: grow at pH below 7.
- Neutrophilic bacteria: grow at pH around 7.
- Alkaliphilic bacteria: grow at pH above 7.
- Specific species: examples include E. coli, Staphylococcus aureus, and Lactobacillus acidophilus.
