“…On the one hand, it may be because urea is beneficial to the expression of specific transporters on its plasma and chloroplast membranes (Lari et al, 2016); on the other hand, the urease contained in C. sorokiniana can release ammonium from urea, which is beneficial to the absorption of C. sorokiniana (Baker, Gobler, & Collier, 2009). Urea has been an important nitrogen source in phytoplankton communities for long time, and the relatively low price helps to reduce production costs (Baldev et al, 2018). Therefore, urea was used as a nitrogen source for C. sorokiniana cultivation.…”

Microalga is a general term for autotrophic single-cell microalgae that can perform photosynthesis. It has various species, wide distribution, rich resources, rapid growth and strong adaptability. Chlorella is a unicellular green microalga rich in protein, polysaccharides, carotenoids, vitamins and other nutrients. It has broad application prospects and has been gradually applied in the fields of food (Matos,

Mass cultivation of microalgae is necessary to achieve economically feasible production of microalgal biodiesel. However, the high cost of nutrients is a major limitation. In this study, corncob extract (CCE) was used as an inorganic and organic nutrient source for the mass cultivation of Chlorella vulgaris (C. vulgaris). Chemical composition analysis of CCE revealed that it contained sufficient nutrients for mixotrophic cultivation of C. vulgaris. The highest specific grow rate of C. vulgaris was obtained at pH of 7-8, temperature of 25-30°C, and CCE amount of 5 g/L. In the analysis using various growth models, Luong model was found to be the most suitable empirical formula for mass cultivation of C. vulgaris using CCE. Analysis of biomass and production of triacyglycerol showed that microalgae grown in CCE medium produced more than 17.23% and 3% more unsaturated fatty acids than cells cultured in Jaworski's Medium. These results suggest that growing microalgae in CCE-supplemented medium can increase lipid production. Therefore, CCE, agricultural byproduct, has potential use for mass cultivation of microalgae.

The Perspective of Large-Scale Production of Algae Biodiesel

We have had high expectations for using algae biodiesel for many years, but the quantities of biodiesel currently produced from algae are tiny compared to the quantities of conventional diesel oil. Furthermore, no comprehensive analysis of the impact of all factors on the market production of algal biodiesel has been made so far. This paper aims to analyze the strengths, weaknesses, opportunities, and threats associated with algal biodiesel, to evaluate its production prospects for the biofuels market. The results of the analysis show that it is possible to increase the efficiency of algae biomass production further. However, because the production of this biodiesel is an energy-intensive process, the price of biodiesel is high. Opportunities for more economical production of algal biodiesel are seen in integration with other processes, such as wastewater treatment, but this does not ensure large-scale production. The impact of state policies and laws is significant in the future of algal biodiesel production. With increasingly stringent environmental requirements, electric cars are a significant threat to biodiesel production. By considering all the influencing factors, it is not expected that algal biodiesel will gain an essential place in the fuel market.
