You shouldn`t worry about writing details of the analysis procedure … EXPERIMENT 1: TEST FOR STARCH IN LEAF Objective Plants produce glucose during photosynthesis. Additionally, NIR supplementation decreased the total carotenoid production. Then, supplementation effects of near-infrared radiation (NIR) LEDs were assessed in the same in parameters. Glucose is a monosaccharide and is shown as part of each of these molecules. Moreover, C. reinhardtii contained relatively high concentrations of chlorophyll (a + b) and total carotenoids (28.6 mg/g DW and 6.9 mg/g DW, respectively) compared with Chlorella (12.0 mg/g DW and 1.8 mg/g DW, respectively) and Spirulina (8.6 mg/g DW and 0.8 mg/g DW, respectively).

The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. If the purple light produces the most photosynthesis and consumes the most C02. The results revealed that the protein content of C. reinhardtii (46.9%) was comparable with that of Chlorella (45.3) and Spirulina (50.4%) on a dry weight basis. This is a template to help prepare you for completing these lab reports. As a result, the pH showed a significant increase after microalgae proliferation, with values ranging from 9.94 to 10.36. This study confirms that, based on its nutrient credentials, C. reinhardtii has great potential as a new superfood or ingredient for a food supplement. Techniques for supplying nutrients and CO2, for mixing and for harvesting and processing the biomass in an energy-efficient manner are still under study and development. The body of Along the way, better understanding of the physiology and cell biology of productive microalgal strains was achieved. The charge separation in the RC is still possible, but energy of excitation becomes thermally dissipated.The very slow photoinactivation process is linked to loss of charge separation ability of the PS II RC and will be analyzed in a forthcoming paper.
