| Summary: | Chlamydomonas reinhardtii Dangeard is the simplest motile, unicellular fresh water alga of class Chlorophyceae. It also functions as the most effi-cient model system for converting solar energy to chemical energy in the form of various metabolites. The objective of the present work is to deal with the growth conditions/growth kinetics of Chlamydomonas reinhardtii Dangeard, required for optimal biomass production. The parameter used to study growth of algae was, photosynthetic measurement, biomass, proteins and lipid measurement, which vary with the change in the cultural condi-tions. Present investigations reveal that change in protein content is posi-tively correlated with the increase in biomass, revealing that the algae can grow rapidly in laboratory/cultural conditions. Lipid content shows a nega-tive correlation with proteins and biomass. Lipids are known to have a role as structural components, in hydration and also in signaling events. Lipids, mainly the triacyl glycerides (TAGs) act as storage compounds enabling the microalgae to survive in adverse environmental conditions. Lipidic content increases in Chlamydomonas reinhardtii increases with optimal light and nutrient system. The increase is in the form of triacyl glycerides which serve as precursors for the production of biodiesel and bioethanol. Conclusion- Further research is required to investigate the interactions of biomolecules and growth of algae. © 2022 Horizon e-Publishing Group. All rights reserved.
