| description | As a counter to climate change, energy crises, and global warming, microalgal biomass has gained a lot of interest as a sustainable and environmentally favorable biofuel feedstock. Microalgal carbohydrate is considered one of the promising feedstocks for biofuel produced via the bioconversion route under a biorefinery system. However, the present culture technique, which uses a commercial medium, has poor biomass and carbohydrate productivity, creating a bottleneck for long-term microalgal-carbohydrate-based biofuel generation. This current investigation aims toward the simultaneous increase in biomass and carbohydrate accumulation of <i>Spirulina platensis</i> by formulating an optimal growth condition under different concentrations of nitrogen and phosphorous in flasks and a bubble photobioreactor. For this purpose, the lack of nitrogen (NaNO<sub>3</sub>) and phosphorous (K<sub>2</sub>HPO<sub>4</sub>) in the culture medium resulted in an enhanced <i>Spirulina platensis</i> biomass and total carbohydrate 0.93 ± 0.00 g/L and 74.44% (<i>w/w</i>), respectively. This research is a significant step in defining culture conditions that might be used to tune the carbohydrate content of <i>Spirulina</i>. |
