Influence of Different Carbon and Nitrogen Sources on Insoluble Inorganic Phosphate Solubilization by Bacillus Subtilis
Phosphate solublization activity of Bacillus subtilis in different carbon and nitrogen sources with insoluble form of phosphate sources like tricalcium phosphate and rock phosphate were studied. TCP solubilization with different carbon sources irrespective of incubation period can be related in the following order: glucose, fructose, arabinose, mannose, sucrose, lactose, and sorbitol. The pH dr...
متن کاملIdentification of Some Molecular Traits in Fluorescent Pseudomonads with Antifungal Activity
We assessed a collection of 47 fluorescent Pseudomonas spp., some with known biological control activity against certain soil-borne phytopathogenic fungi such as, Macrophomina phaseolina, Rhizoctonia solani, Phytophthora nicotianae var. parasitica, Pythium sp. and Fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, HCN and protease. The resu...
متن کاملSiderophores of fluorescent pseudomonads.
Though iron is fourth in abundance in the earth crust it is not readily available to many m icroorga nisms: In the early days of earth life developed in a reductive atm osphere where iron necessary for many physiological processes was abundant in its divalent form. Fe2+-salts are sufficiently w ater soluble to provide an adequate supply of this elem ent to the cells. But as a consequence of th...
متن کاملEnhanced Nematicidal Activity of Organic and Inorganic Ammonia-Releasing Amendments by Azadirachta indica Extracts.
The nematicidal activities of ammonium sulfate, chicken litter and chitin, alone or in combination with neem (Azadirachta indica) extracts were tested against Meloidogyne javanica. Soil application of these amendments or the neem extracts alone did not reduce the root galling index of tomato plants or did so only slightly, but application of the amendments in combination with the neem extracts ...
