Plant Growth Promoting Characteristics of Bacillus Licheniformis DS3 Isolated from Agriculture Field Soil

Authors(4) :-D. Silpa, P. Brahmaji Rao, G. Kranthi kumar, M. Raghu Ram

Plant growth promoting rhizobacteria (PGPR) are known to influence the plant growth by various direct or indirect mechanisms. In search of efficient PGPR strains with multiple activities, a total of 10 bacterial isolates belonging to Bacillus species isolated from different banana field soils, Tadepalli, Guntur district of Andhra Pradesh, India. Out of ten only one strain Bacillus licheniformis DS3 showed potential activity of producing IAA, Gibberellic acid production, Siderophore production and excretion of Ammonia. Bacillus licheniformis DS3 showed the maximum IAA and Gibberellic acid productions are 142 µg/ml and 74.75 µg/ml respectively. An orange halo appears around the Bacillus licheniformis DS3 on CAS agar media indicates the siderophore production. The optimum conditions for IAA production in Bacillus licheniformis DS3 are 0.1 % L-tryptophan, 48 h of incubation, Glucose (1%) and Ammonium sulphate (0.5%) were used as carbon and nitrogen sources. This strain has shown to exhibit multiple plant growth promoting characteristics. These plant growth promoting abilities can make this isolate a potential PGPR candidate for its application in sustainable agriculture.
