ABSTRACT-The enrichment of bedding for vermicomposting systems with organic and inorganic additives is a technique which can promote the quality of produced vermicompost. Phosphate rock and fishmeal are two available and low-cost substances which can be provided easily and inoculation of vermicompost with phosphate solubilizing microorganisms (PSMs) can enhance the availability...

Phosphate solubilizing bacteria have multi-dimensional benefits in broad host range interaction, accessing nutrients, phytohormone induction, stress alleviation, biocontrol activity, and eco-friend approach. This study aimed to evaluate the efficacy of PSB isolates coinoculated with compost, bone meal, DAP fertilizer on tomato growth response. Tomato seeds were treated 10 selected separately gr...

Malacinski, George (Indiana University, Bloomington), and Walter A. Konetzka. Bacterial oxidation of orthophosphite. J. Bacteriol. 91:578-582. 1966.-A variety of bacteria grown on a glucose and salts medium were capable of utilizing orthophosphite as a sole source of phosphorus. Two organisms, Pseudomonas fluorescens 195 and Serratia marcescens 24, were studied in detail. Growth rates and total...

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...

The ability of bacteria isolated from a fixed-film bioreactor to precipitate phosphate crystals for the treatment of domestic wastewater in both artificial and natural media was studied. When this was demonstrated in artificial solid media for crystal formation, precipitation took place rapidly, and crystal formation began 3 days after inoculation. The percentage of phosphate-forming bacteria w...

Bacteria that accumulate polyphosphate have previously been shown to dynamically influence the solubility of phosphatic minerals in marine settings and wastewater. Here we show that dental plaque, saliva, and carious lesions, all contain abundant polyphosphate-accumulating bacteria. Saturation state modeling results, informed by phosphate uptake experiments using the model organism Lactobacillu...

introduction: the most abundant of agricultural soils in iran, are calcareous. in calcareous soils, phosphorus fertilizers use efficiency is low. the usage of soil microorganisms is one of the effective ways to increment the uptake of phosphorus in calcareous soils. this microorganisms using various mechanisms, including the production of plant hormones or the production of organic and inorgani...
