“…The dark reactions of photosynthesis occur in the stroma of the chloroplast and are referred to as the Calvin cycle. Although the Calvin cycle does not utilize light and can happen during the daytime or at night, they employ products of the [19].…”

“…Stage 1: Carbon fixation -Carbon-Fixing Reactions are also known as the Dark Reactions during which CO 2 gas diffuses through and dissolves in the water around the walls of mesophyll cells, diffuses through the cytoplasm and chloroplast membrane into the stomata. In the stroma, CO 2 undergoes a ribulose bisphosphate carboxylase (Rubisco) enzymatic catalyzed reaction with ribulose bisphosphate (RuBP) [19] (Figure 7).…”

“…Two molecules of PGAL are ejected from the cycle in the form of a glucose molecule. The other ten molecules of PGAL are converted to 6 RuBP molecules, using the inherent energy in ATP and the cycle continues [19,20].…”

“…At this stage, the cells are said to be in photoinhibition. Photoinhibition is thus a phenomenon that describes the inability of the photosynthetic organism to support photosynthesis in the presence of excess illumination from a light source [19].…”

Microalgae are unicellular, eukaryotic organisms which possess unique qualities of replication, producing biomass as a precursor for biofuels, nutraceuticals, biofertilizer, and fine chemicals including hydrocarbons. Microalgae access nitrates and phosphates in wastewater from municipalities, industries, and agricultural processes to grow. Wastewater is, therefore, culture media for microalgae, and provides the needed nutrients, micronutrients, inorganic and organic pollutants to produce microalgae biomass. Suitable strains of microalgae cultivated under mesophilic conditions in wastewater with optimized hydrodynamics, hydraulic retention time (HRT), luminous intensity, and other co-factors produce biomass of high specific growth rate, high productivity, and with high density. The hydrodynamics are determined using a range of bioreactors from raceway ponds, photobioreactors to hybrid reactors. Carbon dioxide is used in the photosynthetic process, which offers different growth stimuli in the daytime and the night-time as the microalgae cultivation technique is navigated between autotrophy, heterotrophy, and mixotrophy resulting in microalgal lipids of different compositions.

“…10,11 Only recently, LHCII from B. corticulans was studied and shown to exhibit a longer fluorescence lifetime and a higher fluorescence quantum yield than higher-plant LHCII. 12,13 The ultrafast dynamics in B. corticulans LHCII have also been recently investigated using time-resolved fluorescence spectroscopy and two-dimensional electronic spectroscopy (2DES). 12 Population transfers between Chls were observed at various time scales from hundreds of femtoseconds to several picoseconds.…”
