Microbial nutrients and culture media
6 types of nutritional elements of microorganisms
carbon source
Concept: All nutrient sources that can satisfy the carbon elements required for the growth and reproduction of microorganisms
is a macronutrient
Carbon source spectrum
organic carbon
Heterotrophic microorganisms: Microorganisms that must utilize organic carbon sources
Inorganic carbon
Autotrophic microorganisms: microorganisms that use inorganic carbon sources as their sole or main carbon source
Dual Functional Nutrients
For all heterotrophic microorganisms, their carbon source also serves as a carbon source for energy.
Nitrogen source
Concept: any nutrient source that can provide nitrogen required for the growth and reproduction of microorganisms
Nitrogen source spectrum
amino acid autotroph
amino acid heterotroph
energy
Concept: Nutrients or radiant energy that can provide the initial source of energy for microbial life activities
energy spectrum
Chemical substances (chemotrophic)
Organic matter: energy source for chemoheterotrophic microorganisms (same carbon source)
Organic matter: energy source for chemoautotrophic microorganisms (different carbon sources)
Radiant energy (phototrophic type)
Energy sources for photoautotrophic and photoheterotrophic microorganisms
Monofunctional nutritional "matter" (energy): light radiant energy
Bifunctional nutrients (energy, nitrogen source)
Trifunctional nutrients (carbon source, nitrogen source, energy)
growth factors
concept
Growth factors for autotrophic microorganisms
growth factors heterotrophic microorganisms
Growth factor over-synthesizing microorganisms
Inorganic salt
Lots of elements
General functions
General molecular components in cells (P, S, Ca, Mg, Fe, etc.)
Physiological regulating substances
Maintenance of osmotic pressure (Na⁺, etc.)
Enzyme activators (Mg²⁺, etc.)
Maintain spore heat tolerance (Ca²⁺)
pH stability
special function
Energy sources of chemoautotrophic bacteria (S⁰, Fe²⁺, NH₄⁺, NO₂⁻, etc.)
Hydrogen receptors during anaerobic respiration (NO₃⁻, SO₄²⁻, etc.)
trace elements
Enzyme activators (Cu²⁺, Mn²⁺, Zn²⁺, etc.)
Special molecular structure components (Co, Mo, etc.)
water
nutritional types of microorganisms
Photoinorganotrophic type (photoautotrophic type)
Photoorganotrophic (photoheterotrophic)
Chemolithotrophic type (chemoautotrophic type)
Chemoorganotrophic (chemoheterotrophic)
facultative microorganisms
How nutrients enter cells
Not passing through the carrier protein on the membrane: simple diffusion
through membrane carrier proteins
No energy consumption: promotes diffusion
Energy consumption
Solute molecules remain unchanged before and after transport: active transport
Changes in solute molecules before and after transport: gene translocation
