Phosphorus (P) limits the production of maize, one of the major food crops in China. Phosphate-solubilizing bacteria (PSB) have the capacity to solubilize phosphate complexes into plant absorbable and utilizable forms by the process of acidification, chelation, and exchange reactions. In this study, six bacteria, including one Paenibacillus sp. B1 strain, four Pseudomonas sp. strains (B10, B14,...

In order to screen the strains with Potassium and phosphorus-releasing bacteria from soil, potassium-dissolving medium was used for preliminary screening, transparent circle method re-screening. The content of soluble potassium determined by sodium tetraphenylborate method, phosphorus anticolorimetric molybdenum antimony. were identified morphological, biochemical molecular biology. results sho...

In this study, a total of twenty four phosphate solubilizing bacterial (PSB) colonies were isolated on the Pikovskaya’s agar medium from different effluent exposed sediment of river Ganga. The bacteria showing clear halo zones around their colonies were considered as phosphate solubilizers. Out of 24 phosphate solubilizing bacterial isolates, 4 potential isolates showing highest halo zone on Pi...

Background: Blood stream infection is one of the main causes of morbidity and mortality in patients with cancer. The purpose of this study was to evaluate the prevalence of aerobic and anaerobic-bacteremia in hospital inpatients with cancer and to determine the antibiotic resistance profile in isolated organisms in Kerman, southeast Iran. Methods: Total of 240 blood cultures from 136 patients w...

Pseudomonas putida is a gram-negative rod-shaped gammaproteobacterium that is found throughout various environments. Members of the species P. putida show a diverse spectrum of metabolic activities, which is indicative of their adaptation to various niches, which includes the ability to live in soils and sediments contaminated with high concentrations of heavy metals and organic contaminants. P...

Many camphor-degrading bacteria that are able to transform 2-methylisoborneol (2-MIB) have been identified. Three of these strains have been examined in detail. Rhodococcus ruber T1 metabolizes camphor through 6-hydroxycamphor but converts 2-MIB to 3-hydroxy-2-MIB. Pseudomonas putida G1, which metabolizes camphor through 5-hydroxycamphor, converts MIB primarily to 6-hydroxy-2-MIB. Rhodococcus w...

The influence of trichloroethylene (TCE) on a mixed culture of four different toluene-degrading bacterial strains (Pseudomonas putida mt-2, P. putida F1, P. putida GJ31, and Burkholderia cepacia G4) was studied with a fed-batch culture. The strains were competing for toluene, which was added at a very low rate (31 nmol mg of cells [dry weight] h). All four strains were maintained in the mixed c...
