Growth characterization and biostimulant potential ofCoelastrellasp. D14 a green microalga isolated from a solar panel

Abstract

AbstractExtremophile environments are an important source for finding microorganisms with a potential for biotechnological applications. Among these microorganisms, microalgae contribute to several sustainable processes such as wastewater treatments or nutrition. In this work it was characterized a microalga isolated from a solar panel. The morphological and phylogenetic analysis revealed that the isolate collected was aCoelastrellastrain. Cultivation and stress experiments has shown thatCoelastrella sp.D14 can resist a long period of desiccation and it can grow on cheap sources such as piggery wastewaters (PWW). This work reports that aCoelastrellastrain displays biostimulant properties with a germination index of 123% onLepidium sativumwhen D14 biomass grown at 10% piggery effluent was used. Altogether, these results suggest that this novel strain could be a good chassis for further biotechnological applications.HighlightsCoelastrellasp.
