Bacterial Growth Condition Vocabulary
Ph
Acidophiles: 0.1 to 5.4 this is below neutral and very acidic
Acidophiles can be naturally produced or man made.
Neutrophiles: 5.5 to 8.4 this is neutral
Neutrophiles can be found in bone marrow.
Alkaliphiles: 8-14 this is considered basic
Alkaliphiles are considered prokaryotes, eukaryotes, and archaea.
Temperature
Mesophiles: near 37 degrees
Bacteria growth for mesophiles will be exponential near 37 degrees
Thermophiles: between 45 and 70 degrees
Thermophiles can be found in desert soil
Psychrophiles: can grow at 0 degrees
Psychrophiles can be bacteria, lichens, snow algae, and more
Salt Requirements
Mild Halophiles: need 1-6% salt
Erythrobacter flavus is an example of a mild halophile
Moderate Halophiles: need 6-15% salt
Moderate halophiles are in a heterogeneous group
Extreme Halophiles: need 15-30% salt
Extreme halophiles can survive in salt lakes and solar evaporation ponds
Halotolerant: No salt
Halotolerant bacteria grows without salt
Carbon
Heterotrophs: gain energy from lipids, proteins, and carbohydrates
Humans are considered heterotrophs.
Autotrophs: 2 types
Photoautotrophs: uses light energy/photosynthesis
Plants are considered photoautotrophs.
Chemoautotrophs: use energy from chemicals like carbon
Chemoautotrophs can be found in the sea.
Oxygen Requirements:
Anaerobes
Obligate: O2 will kill them
Obligate anaerobes cannot survive with oxygen presence
Facultative: switch depending on the situation
Facultative anaerobes will grow with or without the presence of oxygen
Aerotolerant: live by fermentation O2 will not kill them
Aerotolerant anaerobes don't use oxygen
Aerobes
Obligate: require O2 for growth
