Abstract |
: |
Trials were made to detect the presence of Thermoalkalophilic
that has ability to nitrogen fixation, in certain soils at Madinah
Munawwarah province, Saudi Arabia. Soil samples were obtained
from two different localities, and they were chemically
analyzed.
The microorganisms used were Bacillus alvei, B. brevis, B. meg-
aterium, B. circulans, and B. pumilus, and they prefer to grow at high
temperature 60?C in media adjusted at pH 10.
The result shows that these isolations have the ability to fix nitrogen.
The biomass and the nitrogenase activity after 24 h at 60?C were:
(Bacillus alvei, 1.5 µg/ml; B. brevis, 1.9 µg/ml; B. megaterium, 1.4
µg/ml; B. circulans, 1.6 µg/ml; and B. pumilus, 1.3 µg/ml). |
