Abstract
Nannochloris oculata Droop, an obligate phototroph, has no absolute nutritional requirement for any organic compounds. However, no growth takes place in neutral media lacking base, due to the lengthening of the initial lag phase. Weak acids shorten the lag even though pH has not been altered. The lag is interpreted as the time taken for the cells to excrete sufficient weak anions to lift the carbon dioxide in solution to the minimum required for growth. Glycollate excretion is discussedin the light of this interpretation.This publication has 4 references indexed in Scilit:
