The least change in the NPV was given with the variance of commodity prices which only lessened the NPV by 3.9% when prices develop at the maximum end, and effected a rise of the NPV by 2.9% when commodity prices were set to a minimum. In fact, selling prices varied tremendously but were disguised through the use of different packaging sizes and content units.

A huge amount of microalgae biomass is required to compete with other feedstocks for sustainable production of bioethanol. 2009;331:5967. Blue-green microalgae (cyanobacteria) are rich in various pigment compounds that enhance the efficiency of light energy utilization (phycobiliproteins) and protect photosynthetic pigments from photo-oxidation (carotenoids). It is also used as food and in the preparations of ice-cream, jellies, sweets and baking. statement and Consequently, these possible variations were accounted for in the sensitivity analysis by altering the selling price of the biomass by 5% and 15%. 2014).

Microalgae produce a wide range of other commercially important and valuable products. Chem Eng Process. US Department of energy multi-year program plan. The most challenging and crucial issues are enhancing microalgae growth rate and product synthesis, dewatering algae culture for biomass production, pretreating biomass, and optimizing the fermentation process in case of algal bioethanol production. Both these fluctuations attributable to the microalgae themselves and the climatic conditions should be reflected in the selling price, which could be used to absorb any instabilities to a certain extent due to uncontrollable cultivation parameters and thus function as a buffer.. In the pharmaceutical and food industries, several synthetic or natural antioxidants have been used to prevent oxidation and peroxidation processes [217]. Microalgae have recently attracted considerable interest worldwide, due to their extensive application potential in the renewable energy, biopharmaceutical, and nutraceutical industries.

Microalgae, single-celled organisms that reproduce fast, occur widely in seawater and freshwater, and are highly adaptable [6]. Algal Res 18:175190. At the same time, they might be more efficiently operated in a humid continental climate to prevent exorbitant cooling costs (Schade and Meier 2019). The baseline scenario showed an ROI of 80.66% after the 30-year lifespan, while positive returns were to be expected after ten years and six months.

Mar Drugs. Singh J, Gu S. Commercialization potential of microalgae for biofuels production. This review shows the practical importance of microalgae for aquaculture, but among these were traced and negative aspects of the excessive development. For that matter, the cost assessment was repeated using P. tricornutum as the cultivated species in the PBR. Those parameters comprised light saturation and photoinhibition, practical losses through reflection, inactive absorption, respiration, and high oxygen rates (Lundquist et al. 2009;23:14551. Long-term anaerobic digestion of microalgae grown in HRAP for wastewater treatment. The extracted sugars need pretreatment to break the polymer molecules to monomeric forms that can be subjected to microbial fermentation to yield bioethanol [8]. Vijayavel K, Anbuselvam C, Balasubramanian MP. They do not contaminate the environment, but they do impose higher costs, due to the consumption of energy [116, 117]. Saudi J Biol Sci. Plant J.

The main areas in the development of algal bioethanol technology, which should be optimized for the commercialization of bioethanol are, selection of the algal biomass, pretreatment and an efficient fermentation process. CO2 constitutes 50% of dry weight of algal biomass. Here, to our knowledge for the first time, we showed that microalgae cultivation in a cold-weather climate is feasible, which enlarges the possible production area for microalgae tremendously.

Cultivation took place from mid-April until mid-October, because an evaluation of the climatic characteristics of the location suggested this period to be most efficient for the cultivation of microalgae, taking into account maximum, minimum and mean daily temperatures as well as solar insolation. Volkman JK.
