Hyperthermophiles Study guides, Revision notes & Summaries

Obligate halophiles - High osmotic pressure aka lots of salt like the great salt lake Facultative halophiles - Type that causes acne can be in salty also known as osmolaric but not nessesary Neutrophiles - Most bacteria Protozoa and pathogens like neutral ph rang 6.5-7.5 Acidophiles - Really acidic as low as 0 pH Alkalineophiles - Grow best in basic range up to 11.5 ex cholera Thermophiles - Higher temperatures above 45C ex hot springs Hyperthermophiles - Hottest 80C and above ...

What is microbial growth? - increase in the number of cells What are the two general requirements for microbial growth? - physical: temperature, pH, osmotic pressure chemical: types of nutrients, growth factors A bacterium has just encountered a new environment. What are its three basic choices with respect to growth in this new environment? - Adapt- allows growth to continue Tolerate- survive without growth DIE What are a bacterium's cardinal temperatures? Do all bacteria have the same...

organic - heterotrophs are? heterotroph - •An organism that must obtain its carbon in organic form •Dependent on eating other life forms inorganic - autotrophs are? autotroph - •"Self-feeder" (photosynthesis or chemosynthesis) •Uses inorganic CO2 as its carbon source; builds organiccompounds from the CO2 phototroph - an organism that gets its energy from sunlight chemotrophs - Organisms that get energy from chemical compounds Photoautotrophs - Capture energy from li...
