Factors affecting microbial growth Flashcards
1
Q
halophiles?
A
Microorganisms that can grow at high
salt concentrations
2
Q
halophiles usually require?
A
NaCl for growth
3
Q
can NaCl be replaced?
A
no it can’t
4
Q
The optimum NaCl concentration for marine microorganisms ?
A
3%
5
Q
for extreme halophiles,it’s btw?
A
between 15 and 30%
6
Q
halotolerant?
A
microorganism that does not require Nacl for growth but can grow in presence of NaCl,substantial levels
7
Q
extreme halophiles
A
micro requires larges amounts of NACL , greather than 10%, in some cases near saturation
8
Q
osmophiles?
A
grow best in the presence of high levels of solute,typically a sugar
9
Q
xerophiles
A
an organim that is able to live best in very dry environment
