ISOLATION, SCREENING, optimization, CHARACTERISATION OF SIDEROPHORE manufacturing bacterium FROM PLA

A total of ninety seven microorganism isolates were obtained from plant rhizosphere collected from Vellamadam village, Tuticorin district, Tamil Nadu, India. Eight of the isolates showed positive for the assembly of siderophore by Blue CAS plate assay. Isolate SA6 showed most siderophore production of sixty six.45% SU in Iron Deficient Succinate Medium (IDSM). The isolate SA6 made process form of siderophore. There was considerably enlarged siderophore production on day a pair of of incubation (62.87% SU) and decline on day three. most siderophore production was discovered at pH half-dozen.8 (50.31% SU) and temperature 34°C (85.1% SU). IDSM showed the most siderophore production (75.90% SU) followed by Barbhaiya & Rao media (67.12% SU). aldohexose as a carbon supply aroused siderophore production of fifty five.7% SU. most siderophore (82.33% SU) was obtained with carbamide as Associate in Nursing freelance atomic number 7 supply the followed by acid (81.46% SU). tryptophane showed a most siderophore production with eighty four.41 SU %, followed by amino acid (82.6% SU). Iron concentration of a hundred millimeter was optimum for the assembly of siderophore. most Siderophore production (91.74% SU) was discovered with Fe-EDTA as iron chelator followed by Tris -EDTA (91.62% SU). Plant growth promoting activities like HCN production, Indole carboxylic acid (IAA) production and nitrate reduction was exhibited by isolate Sturmarbeiteilung half-dozen that indicates it to be an honest PGPR. The sequence sequencing of the isolate SA6 has ninety seven Gestalt principle of organization with enterics fergusonii
