底下的那消最適生長溫度應該是針對某特定菌種
並不是那類細菌都是那個溫度最適吧?
是不是刪掉比較好?
不過這是小地方啦

I hold a different view, according to the medical dictionary definition I found
on the web
http://cancerweb.ncl.ac.uk/omd/

this website is supported by one of the medical schools from England, should
have some academical credibility.
As an example
Def of psychrophile-
An organism able to grow at low temperatures and showing a growth temperature
optimum of more than 15 degrees C.
That is, any organism that satisfies the above description in general.
So, 那一類細菌是對的，非某一特定菌種。

並不是這樣的...
Those "degrees" are borderlines between the optimal growth temperatures of
different thermo-specific bacteria groups.
According to the website mentioned above, we call
organism able to grow at low temperatures and showing a growth temperature
optimum of more than 15 degrees C as "psychrophile";
organism living in the temperature range around that of warm-blooded animals,
usually between 20-45 degrees C as "mesophile"; and
organism that thrives at high temperature as "thermophile"
The most extreme examples are cyanobacteria from hot springs that have
optima of 50-55 degrees C and will tolerate temperatures of 90 degrees.
Thus, those have optimum of 17 are still called psychrophile...

And you said
: Thus, those have optimum of 17 are still called psychrophile...
You misunderstood me, what you said did not contradict with my sayings before.
According to the definition, it is obvious that they were referring to a range
of temperature degrees.
Anyhow, what I meant was that I think you were referring to the type of
microoganisms in this case that can fit the description above.
We call that particular type or 那一類 of microoganisms-psychrophile, not
in terms of some strains or species as chcl said.
