Abstract

Use of C. circinans as described has advantages over the Aspergillus niger method, viz. the change in yield is greater per increment of growth substance added, replicates show lesser variations, temp. fluctuations over a few degrees are of little significance, and successive daily changes in growth rate for a given culture can be recorded and studied.
