Micro study guide 3 - oxygen requirements for bacteria

strict obligate aerobe
a microbe that can only survive in the presence of free oxygen
strict obligate anaerobe
a microbe that can only survive in the absence of free oxygen
strict obligate anaerobe
air is toxic, organism will not survive if exposed to air, require the absence of the oxygen found in the air in order to survive
strict obligate aerobe
require the oxygen found in the air in order to survive, if oxygen is removed or depleted thru use, the aerobic organism will not survive, virtually all higher organisms belong to this group
oxygen is not toxic but can only be tolerated in low concentrations
a microorganism that requires very little free oxygen
facultative aerobe
prefers the absence of oxygen
facultative aerobe
a microorganism that prefers an environment devoid of oxygen but has adapted so that it can live and grow in the presence of oxygen
facultative anaerobe
prefers the presence of oxygen
facultative anaerobe
an organism that prefers an oxygen environment but is capable of living and growing in its absence
what is the percentage of water as it relates to the weight of bacteria
minimum, maximum and optimum
what are the temperature ranges for the three different bacteria
0 - 25 celsius
25 - 40 celsius
40 - 70 celsius
equal concentration of solute inside and outside of the cell
lesser concentration of solute outside the cell
greater concentration of solute inside the cell
mutualism, commensalism and parasitism
ABFSE; a relationship in which organisms of two different species live in close association to the mutual benefit of each
ABFSE; the symbiotic relationship of two organism of different species in which one gains some benefit such as protection or nourishment and the other is not harmed or benefited
ABFSE; an interactive relationship between two organisms in which one is harmed and the other benefits
synergism, antagonism
ABFSE; the harmonious action of two or more microorganisms producing an effect that neither could produce alone
ABFSE; mutual opposition or contrary action. The inhibition of one microorganism by another
biological or organic catalyts
