| Abstract: | The true growth yield and maintenance coefficient for algal growth under batch cultivation are estimated by employing a modified yield model used for continuous systems. The data of aerobic and anaerobic growth are utilized for mixotrophic and photoheterotrophic growth. Chlorella species show the highest bioenergetic yield of 0·6802 for aerobic and mixotrophic growth. Yeast extract proved to be a good nutrient with a high growth yield of 0·7838. Aerobic and mixotrophic growth required less maintenance energy than anaerobic and photoheterotrophic growth: 0·0057 (1/h) and 0·0494 (1/h) for aerobic and anaerobic growth, respectively. It is concluded that mixotrophic growth utilizing glucose is the most efficient process for producing photosynthetic biomass. |
