ActinobacteriaWikipedia
The Actinobacteria are a phylum of Gram-positive bacteria.They can be terrestrial or aquatic. They are of great economic importance to humans because agriculture and forests depend on their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up anew by plants.While this role is also played by fungi Actinobacteria are Jul 23 2020 · Introduction. Tall fescue (Lolium arundinaceum) is a common cool season grass used widely as forage for grazing livestock in the southeastern United States.The grass shares a symbiosis with Epichloë coenophiala a fungus that grows as an endophyte within the plant and provides heat and herbivory resistance from both insects and mammals.The fungus produces ergot alkaloid compounds

In some cases a direct correlation between resistance in farm animals and infection or colonization in humans has been reported for example Ref. 44 . Actinobacteria could reduce the growth (bacteriostatic activity) or kill (bactericidal activity) other microorganisms such as bacteria fungi and even other Actinobacteria thanks to the production of secondary metabolites .
