As the level of starch increased more albumin was needed for optimal growth and at the lower levels of starch, albumin became inhibitory confirming the need for a ratio starch:albumin somewhere between 5:1 and :1. Evidently both ratios and total particles affected growth making it necessary to keep total particles constant while varying the starch protein ratios from 1:1 to 30:1.
