Bioproduction of Indole Acetic Acid by Rhizobium Strains Isolated from Root Nodules of Green Manure Crop, Sesbania sesban (L.) Merr.
Twenty six Rhizobium strains were isolated from root nodules of Sesbania sesban (L.) Merr. collected from different regions of Andhra Pradesh. All the 26 Rhizobium strains produced indole acetic acid (IAA), but maximum amount was produced by only five strains in yeast extract mannitol (YEM) medium supplemented with L-tryptophan. The strains were found to elaborate maximum IAA when fed with 2.5...
متن کاملIndustrial wastewater as raw material for exopolysaccharide production by Rhizobium leguminosarum
The objective of this study was to evaluate the exopolysaccharide (EPS) production by Rhizobium leguminosarum cultivated in wastewater generated by oil companies (WWOC1 and WWOC2) and fish processing industry (WWFP). The results obtained in Erlenmeyer flasks indicated that the rhizobial strain grew well in industrial wastewater. Generally, wastewater composition affected the growth and the EPS ...
متن کاملOptimization of Dairy Sludge for Growth of Rhizobium Cells
In this study dairy sludge was evaluated as an alternative cultivation medium for Rhizobium. Growth of bacterial strains at different concentrations of Dairy sludge was monitored. Maximum growth of all strains was observed at 60% Dairy sludge concentration. At 60% optical density (OD) values are 0.804 for Rhizobium trifolii (MTCC905), 0.825 for Rhizobium trifolii (MTCC906), and 0.793 for Rhizob...
متن کاملA Selective Medium for the Isolation and Quantification of Bradyrhizobium japonicum and Bradyrhizobium elkanii Strains from Soils and Inoculants.
The ecological examination of members of the family Rhizobiaceae has been hampered by the lack of a selective medium for isolation of root nodule bacteria from soil. A novel non-antibiotic-containing medium has been developed which allows selective isolation of Bradyrhizobium japonicum and B. elkanii strains from soil and inoculants. The medium, BJSM, is based on the resistance of B.japonicum a...
متن کاملExtracellular polysaccharide production by a Rhizobium sp. isolated from legume herb Crotalaria saltiana Andr
A symbiont, isolated from root nodules of Crotalaria saltiana Andr., was identified as Rhizobium sp. It produced large amount of extracellular polysaccharides (EPS) in broth culture in yeast extract mannitol (YEM) medium. The EPS production and growth started simultaneously, though they have different stationary phases. The symbiont produced maximum EPS (16 μg/mL) when the medium was supplement...
