“…Starches are synthesized by phosphorylated metabolites in the dark reactions of the photosynthesis cycle using energy-rich phosphate bonds (i.e., ATP) formed in the light reactions [85]. Increased temperature leads to degradation of the starch produced [65,86].…”

Due to significant lipid and carbohydrate production as well as other useful properties such as high production of useful biomolecular substrates (e.g., lipids) and the ability to grow using non-potable water sources, algae are being explored as a potential high-yield feedstock for biofuels production. In both natural and engineered systems, algae can be exposed to a variety of environmental conditions that affect growth rate and cellular composition. With respect to the latter, the amount of carbon fixed in lipids and carbohydrates (e.g., starch) is highly influenced by environmental factors and nutrient availability. Understanding synergistic interactions between multiple environmental variables and nutritional factors is required to develop sustainable high productivity bioalgae systems, which are essential for commercial biofuel production. This article reviews the effects of environmental factors (i.e., temperature, light and pH) and nutrient availability (e.g., carbon, nitrogen, phosphorus, potassium, and trace metals) as well as cross-interactions on the biochemical composition of algae with a special focus on carbon fixation and partitioning of carbon from a biofuels perspective.

“…Mter the first attempts of Emerson, Stauffer & Umbreit (43) to show the participation of energy-rich phosphates in photosynthesis in vivo, many different methods have been introduced and many reactions linked to photosynthesis have been studied. The earlier papers were extensively reviewed by Simonis (200) and Kandler (108).…”

“…This conclusion is further supported by the demonstration of an enzyme system in Chlorella which phosphorylates glucose (15). The high rate of starch deposition in C. vulgaris cultured in a medium containing glucose made this study feasible.…”

Chlorella z~ulgaris was found to deposit starch, in amounts up to 20% of the dry weight of the cells, when grown in a medium containing glucose. 'The cells clid not contain cellulose or chitin. 'The starch was difficult to eutract, being associated with an alkali-soluble, dextrorotatory, cell-wall polysaccharide. 'I'he starch, after extraction by a 26% sotution of calcium chloride a t 120°C., had properties quite similar to starches from higher plants. I t \\.as composed of aiilylose (30-10%) ancl a~nylopectin. Glucose-1-C14 \\.as incorporated into the starch, by growing cells, without much breakdown and resynthesis. Cellfree extracls, obtained from the alga, contained a phosphorylase and a branching enzyme similar to those of the potato. These brought about the synthesis of an amylopectin-glycogen type polysaccharide from glucose-1-phosphate. It is concl~~ded that the mechanism of starch syilthesis in Chlorella vulgaris is essentially the same as in higher plants.
