Bacteria Mineralizing Phytate In The Bean Rhizosphere In An Algerian Agro-Ecosystem

Abstract

Phosphorus (P) is an essential element for plant growth, but its low bioavailability in soil oftenlimits agricultural production, particularly for common bean (Phaseolus vulgaris L.). This study aimed toinvestigate the presence of phytasic bacterial communities in soils with different levels of P deficiency,and their impact on the availability of P for P. vulgaris. The results showed that the phytasic bacterialcommunities carrying the BPP gene were present in both types of soils and were more abundant in the Pdeficient soil and in the rhizosphere compared to the P-rich soil and bulk soil, respectively. This studyhighlights the importance of these bacteria in promoting plant growth and suggests that their density isinfluenced by both soil type and the presence of the plant.
