“…Streptomyces are known to produce lytic enzymes such as amylases, cellulases, chitinases, glucanases, hemicellulases, and ligninases [14,30]. Some of our isolates showed positive activity for amylase, cellulose, and hemicellulose degradation, presenting halo around the Table 4.…”

Control of fungal plant diseases by using naturally occurring non-pathogenic microorganisms represents a promising approach to biocontrol agents. This study reports the isolation, characterization, and fungal antagonistic activity of actinobacteria from forage soils in the Flooding Pampa, Argentina. A total of 32 saprophytic strains of actinobacteria were obtained by different isolation methods from rhizospheric soil of Lotus tenuis growing in the Salado River Basin. Based on physiological traits, eight isolates were selected for their biocontrol-related activities such as production of lytic extracellular enzymes, siderophores, hydrogen cyanide (HCN), and antagonistic activity against Cercospora sojina, Macrophomia phaseolina, Phomopsis sp., Fusarium oxysporum, and Fusarium verticilloides. These actinobacteria strains were characterized morphologically, physiologically, and identified by using molecular techniques. The characterization of biocontrol-related activities in vitro showed positive results for exoprotease, phospholipase, fungal growth inhibition, and siderophore production. However, none of the strains was positive for the production of hydrogen cyanide (HCN). Streptomyces sp. MM140 presented the highest index for biocontrol, and appear to be promising pathogenic fungi biocontrol agents. These results show the potential capacity of actinobacteria isolated from forage soils in the Argentine Pampas lowlands as promising biocontrol agents, and their future agronomic applications.

The genus Streptomyces comprises filamentous Gram-positive bacteria that are widely recognized for their ability to produce bioactive compounds such as antimicrobial, antiparasitic and immune-suppressing compounds via secondary metabolism. These bioactive compounds represent a third of all commercially available antibiotics. Streptomycetes have been found in beneficial associations with plants where they have improved plant growth and protected against pests, which have attracted the attention of researchers worldwide. This review focuses on the potential of streptomycetes as plant growth-promoting bacteria (PGPS) and considers features related to secondary metabolic pathways, interactions with host plants and recent advances in elucidating plant growth-promoting mechanisms. Such advances in basic knowledge have increased the prospects for streptomycetes to be used as bioinoculants for sustainable agriculture.

“…Several Actinobacteria isolation protocols, utilize heating and drying stages to select heat-resistant microorganisms capable of forming spores [11]. Williams and coworkers have suggested thermal treatments between 40-50 °C for 2-16 h for selective isolation of Actinobacteria, reducing significantly accompanying flora [12]. Probably this method was not successful due the temperature used compared with exposure time.…”
