Hello students here 5 questions are asked.
00:03
The first question is to determine the optimal temperature or the range of temperatures for e.
00:18
Coli and pseudomonas orogenosa.
00:32
E.
00:32
Coli is a mesophilic bacteria which are able to grow well in the temperature ranging from.
00:41
21 to 49 degrees celsius however the optimum temperature for the growth of e.
00:54
Coli is 37 degrees celsius pseudomonas grows well at the range of 4 to 42 degrees celsius and the optimum temperature for pseudomonas is 37 degrees celsius where they exhibit maximum growth.
01:22
In the next question they have asked to determine the optimal ph or the range of ph for e.
01:34
Coli and staphylococcus aureus.
01:44
For e.
01:45
Coli, which is the most common prokaryotic bacteria, the optimal ph range is, between 6 .5 to 7 .5 depending on the temperature.
02:03
Growth of staphylococcus aureus occurs over the ph range of 4 to 10 with an optimum ph of 6 to 7.
02:21
Therefore the optimal ph for staphylococcus is 6 to 7.
02:28
In the next question they have given three nutrient broths which is isotonic with 0 .9 % nacl, 2 % nacl and 10 % nacl and they have asked to select which is preferred for e.
02:54
Coli and staphylococcus aureus.
03:04
The answer for this is e...
