| Abstract: | SUMMARY –The effects of heterotrophic and autotrophic growth conditions on the composition of Chlorella are discussed in relation to the potential food value of algae. Cells from the two culture modes differ appreciably in proximate analysis and elemental composition; however, fiber content and vitamin andamino acid composition are essentially unchanged. On this basis it appears that heterotrophic algae, which are less expensive to produce, can be used to examine the acute toxicity problem with bacteria-free cells. In addition, heterotrophic algae may also be used to predict results that would be obtained with autotrophic material in studies of processing techniques designed to improve protein quality and digestibility. |
