Abstract:
... This paper presents a strategy for isolation, identification and evaluation of microalgae strains synthesizing biologically active compounds (BAC) with antimicrobial activity against food-borne and other pathogens. Water samples containing microalgae were initially submitted to the enrichment process, followed by standard procedure for obtaining pure culture. Purified DNA from the microalgae isola ...

Abstract:
... AIMS: Microalgae are ubiquitous in aquatic environments, including aquaculture farms, but few studies have delved into their phytoplankton diversity and bioremediation potential. In this study, the cultivable phytoplankton of a rainbow trout freshwater aquaculture farm was isolated, phylogenetically analysed and used to assemble a consortium to polish an aquaculture‐derived effluent, with low conc ...
