Background: The search for novel antibiotics continues to be of immense importance in research programs around the world for pharmaceutical, industrial and agricultural applications. Filamentous soil bacteria, belonging to the Streptomyces genus, are widely used as an important biological tool for their ability to produce a wide range of novel secondary metabolites, such as "antibiotics".
Objectives: The aim of the present study was to isolate and identify a strain of Streptomyces with high antibiotic production capability.
Contamination of paddy seeds (rice with husk) by Fusarium species can cause spoilage and subsequent production of mycotoxins, especially fumonisins that affect human and animal health. A mycological study was conducted to evaluate the natural occurrence of fumonisin B1 produced by Fusarium proliferatum on paddy grown in different geographic regions of Karnataka (India). A total of 65 isolates of F.
