Synergistic enhancement of glycogen production in Arthrospira platensis by optimization of light intensity and nitrate supply

Characterization of cell growth and starch production in the marine green microalga Tetraselmis subcordiformis under extracellular phosphorus-deprived and sequentially phosphorus-replete conditions

“…This was a much better performance than under nitrogen starvation but somewhat weaker performance relative to that under sulfur deprivation (Brányiková et al 2011). In contrast, nitrogen limitation seemed more efficient than phosphorus limitation in inducing carbohydrate accumulation in Arthrospira platensis (Aikawa et al 2012;Markou et al 2012b). It appears that which nutrient limitation induces the best performance in starch production differs among microalgal species.…”

“…The inverse relation between energy-rich compound (carbohydrate and lipid) accumulation and cell growth has been recorded in many other microalgae (Brányiková et al 2011;Li et al 2008;Wang et al 2010) and is a challenge in the economic production of microalgal biofuel feedstock (Markou et al 2012a). Several strategies, such as "two-stage" cultivation (Dragone et al 2011;Rodolfi et al 2009) or limited nutrient addition (Aikawa et al 2012;Markou et al 2012b), have been employed to solve this problem. Our results showed that unlike starch content and starch productivity, the starch and biomass concentration in the -P culture were comparable to or exceeded those in the -N and -S cultures, suggesting that extracellular phosphorus deprivation might serve as an alternative strategy if the cultivation is targeted to overall biomass and starch production.…”

Evaluation of the integrated hydrothermal carbonization-algal cultivation process for enhanced nitrogen utilization in Arthrospira platensis production

“…A. platensis is capable of producing carbohydrate with a content of more than 60%DW (mainly as glycogen) under N-limitation condition, which shows potential application in nutraceuticals and bioenergy fields (Aikawa et al, 2012Hasunuma et al, 2013). Here the concept for recycling the N contained in the carbohydrate-extracted A. platensis biomass residue was proofed as a biorefinery approach.…”

An overview on biofuel and biochemical production by photosynthetic microorganisms with understanding of the metabolism and by metabolic engineering together with efficient cultivation and downstream processing

“…PCC6803 [165] (Table 1). Glycogen can be produced in halophilic bacterium A. palentensis by manipulating growth condition [166]. Even ammonia can be produced by nitrogen-fixing cyanobacteria Anabaena sp.…”
