Growth promotion of maize by phosphate-solubilizing bacteria isolated from composts and macrofauna.
Five bacterial strains with phosphate-solubilizing ability and other plant growth promoting traits increased the plant biomass (20-40%) by paper towel method. Glasshouse and field experiments were conducted using two efficient strains Serratia marcescens EB 67 and Pseudomonas sp. CDB 35. Increase in plant biomass (dry weight) was 99% with EB 67 and 94% with CDB 35 under glasshouse conditions. I...
متن کاملRole of phosphate solubilizing bacteria on rock phosphate solubility and growth of aerobic rice.
Use of phosphate-solubilizing bacteria (PSB) as inoculants has concurrently increased phosphorous uptake in plants and improved yields in several crop species. The ability of PSB to improve growth of aerobic rice (Oryza sativa L.) through enhanced phosphorus (P) uptake from Christmas island rock phosphate (RP) was studied in glasshouse experiments. Two isolated PSB strains; Bacillus spp. PSB9 a...
متن کاملEffect of immobilized phosphate solubilizing bacteria on wheat growth and phosphate uptake
A study was performed to investigate the efficiency of rhizobacteria on solubilization of rock phosphate and their assimilation by wheat plants in quartz sand potted experiments. Two phosphate solubilizing bacteria, P. fluorescens and Serratia sp. were encapsulated in sodium alginate and potato starch beads and selected to investigate the variation on pH values, the enzymatic activity of alkali...
متن کاملImpact of native phosphate solubilizing bacteria on the growth and development of radish (Raphanus sativus L.) plants
This work was aimed at evaluating the activity of native phosphate solubilizing bacteria on growth and development of radish (Raphanus sativus L.) plants. Bacteria were isolated from the Departament of Sucre (Colombia) soil using selective media (NBRIP), further identifi ed by macroscopic and microscopic observation and biochemically characterized using the API System. Their ability to solubliz...
متن کاملBuffering Reduces Phosphate Solubilizing Ability of Selected Strains of Bacteria
Phosphate solubilizing bacteria (PSB) possessing the ability to solubilize insoluble inorganic phosphates were isolated from rhizosphere soil. Eighty-one potential PSBs thus obtained were quantitatively screened for phosphate solubilization. Of these, four bacteria found to be efficient phosphate solubilizers, were selected for further evaluation, and found that they solubilize tricalcium phosp...
