Oligotroph - Wikipedia
网页An oligotroph is an organism that can live in an environment that offers very low levels of nutrients. They may be contrasted with copiotrophs, which prefer nutritionally rich environments. Oligotrophs are characterized by slow growth, low rates of metabolism, and generally low population density.
Oligotrophy - an overview | ScienceDirect Topics
网页Oligotrophy is defined as the ability of microbes to grow when concentrations of nutrients are very low or absent. Although oligotrophy generally has been considered the domain of prokaryotes, sufficient evidence is available to support the idea that fungi also can grow oligotrophically ( Wainwright 1993 ).

网页Small (<3 μm) single-celled picocyanobacteria, most notably of the genera Prochlorococcus and Synechococcus, dominate vast expanses of the global oceans and often constitute ∼25% of oceanic photosynthetic production and biomass ( …
网页1. Introduction. According to A. Koch's interpretation (Koch, 1971), Escherichia coli has evolved a strategy for surviving a "feast and famine" existence. Oligotrophic bacteria, in contrast, are conceived of as those never invited to a feast; their properties should include microbial adaptations to uninterrupted nutrient limitation.
