South American Leaf Blight (SALB) of the rubber tree, caused by Microcyclus ulei and foliar anthracnose caused by Colletotrichum gloeosporioides, are diseases that adversely affect rubber cultivation in America. Both diseases have a significant economic impact on this agricultural subsector. The aim of the present study was to evaluate the potential as biological control agents of three Streptomyces species strains, namely A20, 7.1 and 5.1, against M. ulei and C. gloeosporioides. The results of analysis of variance (ANOVA) and Tukey post-hoc test of the in vitro antifungal activity assays evidenced the potential of the three Streptomyces strains to inhibit C. gloeosporioides growth through the production of diffusible (A20 and 5.1) and volatile compounds (7.1). Furthermore, other results indicated that strain 5.1 had a high biocontrol activity against C. gloesporoides, and thus such strain was selected for further evaluations as a possible biocontrol agent against M. ulei. In vitro assays suggested that active compounds produced by 5.1 inhibited M. ulei growth by interfering with conidia germ tube and stroma formation. Bioassay-guided fractionation with organic solvents of 5.1 fermentation broths, suggested that antifungal compounds produced by this strain were nonionic compounds of medium-polarity. Currently, studies are ongoing to elucidate the chemical structure of these antifungal compounds. These approaches aim to generate a biological control agent to provide the Colombian rubber subsector with a preventive measure for controlling M. ulei and C. gloeosporioides.

“…VE2 was isolated from the stem tissues of Vernonia cinerea (L.) Less. by the surface-sterilization technique (Taechowisan et al, 2003). Identification of the isolate to species level was based on morphology, chemotaxonomy and also 16S rDNA sequencing as described in our previous study (Taechowisan and Lumyong, 2003).…”

“…Since bioactive compounds from endophytic Streptomyces have distinct chemical structures and some of them are novel compounds. In our previous studies, many endophytic Streptomyces were isolated from plant tissues, some of them produced the secondary metabolites against bacteria and phytopathogenic fungi (Taechowisan et al, 2005(Taechowisan et al, , 2008(Taechowisan et al, , 2012(Taechowisan et al, , 2014.…”

Strain VE2 was isolated from the stem tissue of Vernonia cinerea (L.) Less. and identified as Streptomyces sp. on the basis of morphology, chemotaxonomy and 16SrDNA sequencing. The fractionation of the crude ethyl acetate (CEA) extract from VE2 cultures led to the isolation of two acetogenins; squamocin and rollidecin B; these compounds and CEA extract had potential in antibacterial and antioxidant activities. The crude extract showed the highest activity against Salmonella Typhi ATCC19430 and Bacillus cereus ATCC7064, with MIC values of 32 µg/ml. Squamocin also showed the lowest MIC (32 µg/ml) and Minimum Bactericidal Concentration (MBC) (128 µg/ml) against S. Typhi and B. cereus with corresponding large diameter of the zone of inhibitions (27.5 and 28.2 mm, respectively). Rollidecin B showed the highest DPPH antioxidant activity with SC50 value of 58.92 µg/ml.
