Forty isolates of endophytic bacteria isolated from banana tree roots were assessed as to their capacity to solubilize phosphate in a solid culture medium supplemented with different inorganic and one organic source of phosphorus. The amount of phosphorus (P) in each liquid medium was quantified, and an indirect assessment of acid phosphatase activity was performed. All assays had a fully rando...

Endophytic fungi promote plant growth through the production of IAA, siderophore and phosphate solubilization. Out of thirty fungal endophytes isolated from tomato roots grown in a stressed, cold climate of Central Himalayan hills of district Pithoragarh, Uttarakhand, India twelve showed distinct morphological and study was undertaken, to understand the plant growth promoting properties possess...

Abstract Many agricultural researches have been performed to improve soil productivity. Nitrogen (N) and Phosphorus (P) are essential elements which are utilized by the plants in large amounts. Phosphorus can be provided by applying chemical fertilizers. Microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this proces...

Here, we report the complete genome sequence of the phosphate-solubilizing bacterium Burkholderia cenocepacia CR318, consisting of three circular chromosomes of 3,511,146 bp, 3,097,552 bp, and 1,056,069 bp. The data presented will facilitate further insight into the mechanisms of phosphate solubilization and its application for agricultural and ecological sustainability.

The undertaken study was conducted to isolate and characterize the plant growth promoting rhizobacteria from rhizospheric soil of Musa itinerans collected Zaphumi village, Nagaland, Northeast India. purified bacterial isolates were screened for growth-promoting traits namely phosphate solubilization, IAA production, siderophore ammonia production. Out 25 isolates, three best with maximum select...

Preparations of heterocysts of Anabaena cylindrica Lemm. had 7- to 8-fold higher activities of glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, 2-fold more hexokinase activity, and 0.02 to 0.06 times as much ribulose diphosphate carboxylase and glyceraldehyde 3-phosphate dehydrogenase activities as did whole filaments per milligram soluble protein in cell-free extracts. T...

A study was conducted at Universiti Putra Malaysia to determine the effect of phosphate-solubilizing bacteria (PSB) and organic acids (oxalic & malic) on phosphate (P) solubilization from phosphate rock (PR) and growth of aerobic rice. Four rates of each organic acid (0, 10, 20, and 30 mM), and PSB strain (Bacillus sp.) were applied to aerobic rice. Total bacterial populations, amount of P solu...

The efficacy of strains of Pseudomonas fluorescens, Bacillus megaterium and Azospirillum spp. in in vitro solubilization of Ca3PO4 was studied. Pseudomonas fluorescens and Bacillus megaterium strains were the most powerful phosphate solubilizers on Pikovskaya (PVK) plates and liquid medium. Azospirillum lipoferum strains showed weak zones of solubilization on the PVK plates. Phosphate solubiliz...
