Abstract
Phosphate Solubilizing Bacteria (PSB) may aid in the process of solubilizing phosphorous elements from their binding so that they are readily accessed by plants, increasing their effectiveness and the soil's availability of phosphorus. The dynamics of organic matter decomposition, the availability of plant nutrients like nitrogen, phosphate, and sulphur, as well as promoting plant growth, are significantly regulated by soil microbes. In Saluga and Ghazal Protected Area, Aswan, Egypt, the Cardiospermum Halicacabum (balloon vine) plants are being studied with the aim of isolating and defining the morphological properties of the P solubilizing bacteria colony there. Thirteen bacterial isolates from Cardiospermum Halicacabum plant were found exhibited P-solubilization potential. The morphological characteristics of the isolates, inclusive the form, margin, shape, elevation, and color of the colony, were gained. The bacteria found were gram + and gram -, which are 69.23% and 30.77% . Furthermore, Using thirteen different bacterial isolates, a clean zone measuring 11–26 mm was produced. Phosphate's dissolving index ranged from 2.11 to 2.38, while its solubility ranged from 111.11 to 137.50.
