Bacillus coagulans, a phosphatase- and phytase-producing bacterium was isolated
and tested under greenhouse conditions and in the field in a loamy sand soil.
Bacterial population build-up and efficiency was compared under sterilized and
non-sterilized soil conditions. Exploitation of plant unavailable (poorly soluble) P
was higher in sterilized soil, mainly due to an increased bacteria population. A
gradual increase in microbial build-up of up to 21 times the inoculated population
was observed over a 4-week period under the sterilized soil condition. Clusterbean
influenced acid phosphatase and phytase activity. The depletion of organic P was
much higher than the depletion of mineral and phytin P. The microbial
contribution to the hydrolysis of the different P fractions was significantly higher
than the plant contribution. The maximum effect of inoculation on different
enzyme activities (acid phosphatase, alkaline phosphatase, phytase and dehydrogenase) was observed in pants between 5 and 8 weeks of age. A significant
improvement in plant biomass (25%), root length (28%), plant P concentration
(22%), seed (19%) and straw yield (28%) resulted from inoculation. The results
suggested that B. coagulans produces phosphatases and phytase, which mobilized
P from unavailable native P sources and enhanced the production of clusterbean.
