A thermosensitive wild-type strain (PP201) of Rhizobium sp. (Cajanus) and its 14 heat-resistant mutants were characterized biochemically with regard to their cell surface (exopolysaccharides (EPSs) and lipopolysaccharides (LPSs)) properties and protein profile. Differences were observed between the parent strain and the mutants in all these parameters under(More)
Fourteen heat resistant mutant strains were isolated from a wild-type strain (PP201, Nod+ Fix+) of Rhizobium sp. (Cajanus) by giving it a heat shock of 43°C. These mutant strains showed a greater increase in optical density (O.D.) and a higher viable cell count in both rhizospheric and non-rhizospheric soil at high temperature. Symbiotic studies showed that(More)
Different explants of Rauwolfia serpentina were tested for their capacity and root differentiation. MS sedium containing 2.0 mg I-1 BAP or 1.5 mg I-1 BAP with 0.5 mg I-* NAA gave the best shoot proliferation from shoot apices (84.12%). Multiple shoots subcultured on the same media gave higher number of shoots (6–9). Callus formed at the cut ends of explants(More)
Seaweeds are the macroscopic algae, devoid of roots, stem and leaf and constitute one of the most important marine living resources. On the basis of pigments seaweeds are divided in to three groups, viz., Green (Chlorophyceae), Brown (Phaeophyceae), Red (Rhodophyceae) algae. The liquid fertilizers that are derived from seaweeds are known as seaweed liquid(More)
