Microbiology, part 30: Growth - Microbial Growth Requirements

Requirements for microbial growth. Oxygen requirements and explains the difference between obligate aerobes, obligate anaerobes, facultative anaerobes, aerotolerant anaerobes, microaerophiles, and capnophiles. Temperature requirements and explains the difference between mesophiles, psychrotrophs, psychrophiles, thermophiles, and hyperthermophiles. PH requirements and the difference between neutrophiles, acidophiles, and alkaliphiles. In terms of osmotic requirements, the difference between halophilic and halotolerant organisms. Lastly, chemical requirements of microorganisms, including: carbon, nitrogen, phosphorus, sulfur, and trace elements (e.g., iron, copper, zinc).
