NUTRITIONAL REQUIREMENTS FOR MICROBIAL GROWTH

• Energy, Electron, Carbon, Nitrogen, Oxygen, Microaerophilic, Sulfur, Phosphorus, Trace Elements, Metal Ions, Growth Factors, Water, Living host system
• Chemotroph and Phototroph are the two requirements in the category of energy
• Lithotroph and Organotroph are the two requirements for the category of Electron
• Chemotroph - chemical compounds
• Phototroph - light
• Lithotroph - reduced inorganic compound
• Organotroph - organic compounds
• Autotroph - carbon dioxide as sole source
• Heterotroph - other organic compounds
• Oxygen includes Obligate anaerobe, Aerobe, Facultative anaerobe, and Microaerophilic
• Calcium (Ca), Manganese (Mg) , Iron (Fe), Sodium (Na) - most not needed metal ions
• Halophile - requires at least 7% Na
• Growth Factors includes Amino acids, purines, pyrimidines and vitamins
