  The present study explores the efficacy of an endophytic fungus from plant Achyranthus aspera, an herb of medicinal importance. Considering limitation of secreted fungal metabolites in terms of biologically active molecules; an endeavour was made to increase the amount of secreted active product. Enhanced secretion of active compound was observed by optimizing different parameters of culture conditions. The fungal culture was isolated from stem of Achyranthus aspera and taxonomically identified as Aspergillus terreus. While analysing it’s different in vitro potential, culture metabolites showed antibacterial, antifungal and anti-oxidant activity. In order to increase the yield of crude compounds, culture was optimized for different parameters such as carbon and nitrogen sources and extracting solvent. All the optimization was performed based on % inhibition of bacterial growth w.. View More»
