Identification and antifungal activity against plant pathogens of actinomycetes strain A50
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 12
Abstract
"This study aimed to obtain actomycetes with high activity against plant pathogens from soil. Soil samples were collected from woodlands of Lake Chi’ao in Shenzhen. Actinomycetes strain A50 was isolated using serial dilution and plating method on Gause's Synthetic Agar Medium. Based on morphological, physiological and biochemical characteristics, as well as the analysis of 16S rDNA, the strain A50 was was identified as Streptomyceyes nodosus. The antifungal activity of A50 was studied by flat confrontation. The result of mycelium growth rate showed that A50 had a broad spectrum inhibitory activity to all the tested 5 plant pathogenic fungi. Among these, activity against Bipolaris maydis was the highest with the width of inhibitory zone above1.5cm. The fermentation solution of A50 displayed 68% inhibition activity to sclerotium treated after 72h. A50 had big potential and wide prospect for controlling plant pathogens."
