Chemotrophs
energy from chemicals
Phototrophs
energy from light
Chemoorganotrophs
energy from organic compounds
Chemolithotrophs
organisms that obtain energy from the oxidation of inorganic compounds
Heterotrophs
Organisms that depend on other organisms for their food. (Carbon)
Autotrophs
Organisms that make their own food (self-feeder) (CO2- carbon dioxide)
Organic
contains carbon and hydrogen
Saprobes (chemoheterotroph)
organism that obtains food from decaying organic matter (dead organisms)
Parasites (chemoheterotroph)
Gets nutrition from living organisms and cause harm to the host
Microbial Growth is influenced by
Temperature
Gases
pH
,Osmotic pressure
Hydrostatic pressure
osmotic pressure
the external pressure that must be applied to stop osmosis
hydrostatic pressure
atmospheric pressure
Psychophiles
Cold loving microbes -optimum temp = 10C temp range = -10-20C
Psychrotolerant
tolerate cold temperatures (adaptations in their cytoplasmic membranes)
Mesophiles
moderate temperature loving (prevalent in the human body)
Thermophiles
heat loving microbes
extreme thermophiles (archaea)
love very hot environments 125 degrees optimally
Obligate Aerobe
requires oxygen to grow and cannot live without it
, Faculative anaerobes
can live with or without oxygen
aerotolerant anaerobes
tolerate but cannot use oxygen
obligate anaerobes
Organisms that cannot live where molecular oxygen is present
Microaerophiles
require oxygen concentration lower than air
Neutrophiles
Grow in habitats that range between 6 and 8
Halophiles
salt loving
(osomotic pressure)
Barophiles
organisms that live under REQUIRE high pressure (atmospheric pressure)
lag phase of bacterial growth
The first phase of the bacterial growth curve is when organisms acclimate to their
surrounding; they grow in size but do not increase in number.
