In most phosphorus (P) sorption studies, P is added as an inorganic salt to a predefined background solution such as calcium chloride (CaCl2) or potassium chloride (KCl); however, in many regions, the application of P to agricultural fields is in the form of animal manure. The purpose of this study, therefore, was to compare the sorption behavior of dissolved reactive P (DRP) in monopotassium p...

An L-form isolated from Escherichia coli K12 by sequential treatment with N-methyl-N'-nitro-N-nitrosoguanidine and lysozyme was adapted to grow in hyperosmolar liquid cultures. It was stable in the absence of antibiotic when cultured in brain heart infusion (BHI) broth containing NaCl and CaCl2, the optimal concentrations being 0.34 M and 1 mM, respectively. No growth of the L-form was observed...

phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (p) forms to soluble and bioavailable p. the aim of the present study was to isolate p solubilizing bacteria from forest soils around the rock phosphate (rp) mine of koh-e-sepidlar in kohgiluyeh and boyer ahmad province and evaluate their ability in sperber culture medium and wheat straw medium in the presen...

Calcium chloride is commonly included in buffers used to generate chemocompetent bacterial cells. The mechanism that underlies the uptake of exogenous DNA into bacteria is not completely understood. Previous studies have suggested that calcium ions may function to neutralize electrostatic repulsion between DNA and membrane proteins, thereby allowing exogenous DNA to enter membrane pores. Other ...

The aim of the present study was to investigate the effect of the mammalian target of rapamycin (mTOR) signaling pathway on thoracic aortic aneurysm (TAA) development. The study used a calcium chloride (CaCl2)‑induced rat TAA model to explore the potential role of mTOR signaling pathway in the disease development. Adult male Sprague‑Dawley rats underwent the periarterial exposure of thoracic ao...
