ABSTRACT

It is necessary to bubble the experimental and control samples simultaneously for removing the residual ¹⁴CO₂ after its consumption by algae. The control sample is a nonbacterial preparation, to which the same quantity of NaH¹⁴CO₃ was added as to the control sample and which was subjected to the same operations. The quantity of dissolved organic matter excreted by algae is calculated as a difference between control and experimental values.
