ISOLATION, SCREENING, improvement, CHARACTERISATION OF SIDEROPHORE manufacturing microorganism FROM PLANT RHIZOSPHERE

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 created process form of siderophore. There was considerably raised siderophore production on day a pair of of incubation (62.87% SU) and decline on day three. most siderophore production was ascertained at hydrogen ion concentration six.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 excited siderophore production of fifty five.7% SU. most siderophore (82.33% SU) was obtained with organic compound as Associate in Nursing freelance chemical element 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 one hundred millimeter was optimum for the assembly of siderophore. most Siderophore production (91.74% SU) was ascertained with Fe-EDTA as iron chelator followed by Tris -EDTA (91.62% SU). Plant growth promoting activities like HCN production, Indole ethanoic acid (IAA) production and nitrate reduction was exhibited by isolate reserves six that indicates it to be an honest PGPR. The factor sequencing of the isolate SA6 has ninety seven Gestalt law of organization with enteric bacteria fergusonii
