background and objectives: phosphorus is one of the low bioavailable macroelements. use of microorganisms in biofertilizers could release phosphorus from insoluble compounds. pseudomonas putida p13 and pantoea agglomerans p5 are well recognized for application as phosphate solubilizing bioinoculants and are used as solid carrier based. liquid bioinoculants are preferred for economizing producti...

1. Four of the known components of wall preparations of vegative cells of Bacillus licheniformis N.C.T.C. 6346 have been isolated free of each other after successive treatments of the walls with trichloroacetic acid and lysozyme: (a) a mucopeptide consisting of glucosamine, muramic acid, alphain-diaminopimelic acid, glutamic acid and alanine in the molar proportions 1.0:0.8:1.0:1.2:1.7; (b) an ...

Phosphorus is essential to all forms of life and its contribution towards aiding the native soil fertility sustaining it, well known. With passage time, P added undergoes transformation into various unavailable forms. Native compounds, some being highly insoluble are mostly for plant uptake. The availability phosphorus plants depends on properties, pH, soluble iron, aluminum manganese, calcium ...

Continuous application of phosphatic fertilizers in association with its low recovery results the insoluble legacy P buildup agricultural soils. In this study, a field experiment was conducted maize hybrid COH(M) 6 to know effect different activators (Farmyard Manure, Humic acid, Phosphorus Solubilising Bacteria, and Phytase) on increasing phosphorus (P) availability. The were combined applied ...

Strain P17 was a bacterial strain identified as Bacillus megaterium isolated from ground accumulating phosphate rock powder. The fermentation broth of strain P17 and the yellow-brown soil from Nanjing Agricultural University garden were collected to conduct this study. The simulation of fixed insoluble phosphorous forms after applying calcium superphosphate into yellow-brown soil was performed ...

phosphorus is one of the most important nutrients for plant growth and development. chemical pi fertilizer is used to provide the phosphorus for the plants, but it is mostly fixed in the soil into insoluble form and become unavailable to the plants. phosphate-solubilizing bacteria have lots of application in agriculture as biological fertilizer. consumption of biofertilizers instead of chemical...

Ten indigenous bacterial isolates were identified as efficient mineral phosphate solubilisers namely 7 strains of Klebsiella pneumoniae, 2 strains of Enterobacter aerogenes and 1 strain of Pseudomonas aeruginosa. All the ten strains were able to dissolve calcium phosphate (Ca-P), ferric phosphate (Fe-P) and aluminium phosphate (Al-P) efficiently. STMPSB 8 (Klebsiella pneumoniae) could be design...

Biofertilization with plant growth-promoting bacteria (PGPB) could optimize chemical fertilization for strawberry crop cultivation. A greenhouse study was arranged to assess the impact of an isolated PGPB consortium from halophytes on development, physiological traits, and nutritional balance subjected two phosphorus limitation treatments (with without insoluble form application). had a positiv...

The isolation of phosphate solubilizing bacterial strains exhibiting high ability to solubilize soil phosphorus is a matter of great interest with high applicability. The use of phosphate solubilizing bacteria as inoculants simultaneously increases phosphate uptake by the plant and increase crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium species are among the most powerf...

Aspergillus niger is a type of soil fungus with the ability to dissolve insoluble phosphate and secrete organic metabolites such as citric acid. However, whether cell-free fermentation broth (AFB) promotes maize growth alleviates low-phosphorus stress has not been reported. In this study, we explored their relationship through hydroponics system. The results indicated that either too low or hig...
