General description

Trace Metal Mix A5 with Co is a supplement supplying trace elements for the growth of blue green algae and act as a fertilizer. Cyanobacteria have relatively high metal requirements for optimal growth compared to other bacteria largely due to metal cofactors in the oxygenic photosynthetic electron transfer apparatus, such as cytochromes, plastocyanin and chlorophyll rings. An adequate supply of trace metals is required to maintain optimal growth, particularly as these higher metal requirements make Cyanobacteria more prone to trace nutrient limitation. Co acts as a determinant of marine cyanobacteria distribution and productivity.
