Abstract

The autotrophic and photoheterotrophic growth of light pre‐treated and dark pre‐treated strains of Westiellopsis prolifica was decreased in the presence of NH, NO and urea in the culture medium. On dark incubation, after pre‐treatment with light as well as in the dark, the alga showed better growth response to all the combined nitrogen sources. However, only the light pre‐treated strain of the organism utilized the exogenous nitrogen sources appreciably for its dark heterotrophic growth.
