Characterization of Streptomyces strain CMU-MH021, a nematicidal actinomycete isolated from plant-parasitic nematode-infested soil in northern Thailand
In a previous study, we determined that nematicidal actinomycete strain CMU-MH021 had an effect on root-knot nematodes and also produced siderophore and indole-3-acetic acid (IAA). In this study, strain CMU-MH021 was taxonomically characterized. The strain was found to contain chemical markers typic...

| Summary: | In a previous study, we determined that nematicidal actinomycete strain CMU-MH021 had an effect on root-knot nematodes and also produced siderophore and indole-3-acetic acid (IAA). In this study, strain CMU-MH021 was taxonomically characterized. The strain was found to contain chemical markers typical of members of the genus Streptomyces, possessing a broad spectrum of antimicrobial activity against Gram-positive and Gram-negative bacteria, fungi, and algae. In addition, this strain showed no toxic effect on brine shrimp and tomato. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain CMU-MH021 forms a distinct cladewithin the genus Streptomyces neighbor-joining tree and is closely related to the S. hiroshimensis cluster. © 2012 Springer-Verlag and the University of Milan. |
