Algae as Nutrient Material for studying Ca-Sr Relationships in Heterotrophic Organisms

Article metrics


A RECENT review of the mineral nutrition of algae1 summarizes the inorganic requirements and substitution elements for a number of green algal forms. Among those presented, it was especially noted that algae which can grow with an Sr replacement for Ca, such as Chlorella2 or Protosiphon3, constitute a potential tool for investigating Ca nutrition in heterotrophic organisms. They may be particularly useful for comparing the effects of an adequate Ca supply with the effects of making Ca deficient and replacing it with Sr.
