- Abstract
The present study was conducted to analyze the biomass and lipid accumulations in the red alga Galdieria sulphuraria under mixotrophic conditions. It has also proven that G. sulphuraria to be useful for biofuel and other valuable compound production. In recent studies, it has been seen that sugar beet molasses and glucose yielded higher biomass and lipid content. However, these studies have not led to the analysis of the role of other sugars as the carbon sources. The first goal of this research effort is to evaluate the biomass and total fatty acid, lipid and Calvin cycle in different sugars as carbon sources. According to this study the specific growth rate was higher when the cells were grown under mixotrophic culture condition on equal molar concentration of C atoms from glucose, fructose, sucrose and glycerol. However, maximum biomass production was achieved in the cultures grown on glucose and glycerol as the carbon sources. These results showed that glycerol is the best carbon source for the Galdieria growth under mixotrophic condition. Furthermore, we present the amount of total lipids and fatty acids and metabolism in the mixotrophic culture conditions.
