Plant Growth Promoting Attributes of Streptomyces sp.. Plant Growth Promoting activities

      Аннотация: Microorganisms serve as potential biological control agents to control plant pathogens with no effect on the environment or other non-target organisms. Among the microbial groups, actinomycetes are known to produce bioactive antimicrobial compounds and plant growth promoting regulators which can improve agricultural developments. Thus, these actinomycetes are the subject of current research with regard to sustainable agriculture practices. The book was dealt with actinomycetes from medicinal plants rhizosphere soils by morphological, biochemical and molecular characterization. These organisms were assessed for their antiphytopathogenic activity against fungi in addition to plant growth promoting properties. An elaborate effort was made to optimize the process parameters required for its antifungal secondary metabolites production through non statistical and statistical approach. Antifungal activity was assessed by well and disc diffusion method and its MIC were determined by standard methods. The bioactive principle was purified and identified through TLC, Column chromatography, UV, FTIR, GCMS and NMR analysis.
