Abstract:

In this study, we have investigated the ability of Staphylococcus haemolyticus designated 15%S5-H-2 strain, a multifunctional salt-tolerant plant growth-promoting bacteria (ST-PGPB). The bacteria were isolated from rhizosphere soil from a salt production pond near Coringa Mangrove forest, Kakinada, Andhra Pradesh, INDIA. The bacteria were capable of producing Auxin indole -3 acetic acid (41μg/ml), solubilizing insoluble phosphate, siderophore and ammonia, synthesizing other plant growth-promoting enzymes. It has shown positive results for antibacterial and antifungal activities and salt tolerance up to 25%NaCl (optimum growth at 3-6% NaCl). The growth occurred at temperatures from 18°C–45°C (optimal growth at 35°C). The tested bacteria significantly enhanced the growth of two plants black gram and rice in comparison to control.
