“…These systems allow using solar energy for the accumulation of various organic compounds which may be used for the production of both BF and a number of valuable by-products [40,167,168]. There are several reports on the creation of the third generation of BF production technologies which allow processing algae, including specifically cultivated ones, into BF [169][170][171][172][173]. At the same time, some authors pose the question of whether it is possible to use contemporary technologies of algae processing effectively for environmentally clean production of BF and cleaning of wastewater [46,174].…”

Diffusion of the biofuels (BF) using is justified by opening up the opportunities for obtaining fuel and energy from previously inaccessible sources and by the existence of energy-deficient regions, in particular in Russia. Works of different scientists on the problems of creating and using BF were the methodological basis of this study. Information on the state and prospects of the development of renewable energy sources in Russian regions was collected from regulatory documents and was obtained by employing a questionnaire survey. For the study of the collected materials, the different methods of comparative analysis, and the methods of expert assessments were used. The results of the Status-Quo analysis of BF production in Russia have shown that the creation of BF performed relatively successfully. However, there are many more perspectives, connected with expanding the utilization of the different raw materials. Also, the analysis of organizational and economic mechanisms applied for production of BF and the obtained data on several organizations-producers allowed for proposing six indexes for the assessment of the BF production effectiveness. It is suggested that BF production in Russia will contribute to the sustainable development of a number of the country's regions in the near future.Energies 2019, 12, 3948 2 of 30 impact of permanent anthropogenic factors has required the taking of appropriate measures in this field both at the federal and regional levels. In particular, the accumulation of industrial, agricultural, and household wastes is becoming an essential incentive for the development of innovative activities aiming at the production of biofuel (BF). According to the existing data [3], the resource potential of recyclable organic waste biomass, including solid household wastes and sediments of wastewaters reaches 13,490.26 tons of coal equivalent (TCE) per year in Russia. This study led both at the federal level and in particular regions which have significant differences in terms of economic, geographic, and climatic conditions. According to pessimistic forecasts, the share of green energy in the Russian economy will arrive at 3-5% by 2035, according to positive ones, it will be equal to 8-10%. The proposed share of BF in the production of electric and heat energy with targeted management could be about 2-3% [4].Different geographic, climatic, economic, and other conditions in regions of Russia necessitate solving several scientific problems for optimization of the existing regional programs for the provision of sustainable development and determination of the role of REn and BF production in them.Therefore, the progress in BF production achieved in some leading countries has become a significant factor which causes a positive impact on the sustainable development of their economies. This gives rise to the suggestion that Russia has some conditions for a more extensive application of REn, in particular, for BF production and use. Correspondingly, this article characterizes some general trends of B...

“…According to Chen et al, (2015); Collotta et al, (2018), the addition of CO 2 along with waste water enhance the algal growth at a high rate. The algal genera such as Chlorella, Scenedesmus, and Chlamydomonas are reported effectively to utilize the nutrients of waste water accompanied with biofuel production.…”

“…According to Stephens et al, (2010); Hannon et al, (2010); Collotta et al, (2018), microalgae fast growth rate, vigorous vivacity along with their ability to bio-remediate the pollutants from waste water without the use of fertilizers or pesticides, make them a strong candidate for biofuel production especially for the fossil fuel importing countries. USA has planned to run 20% of its road transport through the use of biofuel by 2022 (Collotta et al, 2018). From these mentioned algal features, it can be surmised that microalgae are one of the world's most commendable, renewable and sustainable fuel resource which can also play their role to reduce the environmental pollution (Adeniyi et al, 2018).…”

The shortage of fuel in the near future and the change in climate due to greenhouse gases are serious challenges of a global concern, thus it is imperious to explore new sustainable ways to overwhelm these challenges. The need of a new sustainable energy sources has increased the importance of the third generation biofuel produced from non-food stocks such as algae, which possibly represent a great opportunity in the long term. The major challenge of the algae based bio-fuel production is their extraordinary cultivation costs, which make their commercialization economically infeasible. Algal spp. especially Chlorella spp. are capable of thriving in waste water and can accumulate high lipid contents. The aim of the current review was to highlight the possible integration of waste water treatment and algae based bio-fuel production, as a sustainable option for cost effective bio-fuel production along with lower environmental impact.

“…Microalgae are unicellular photosynthetic micro‐organisms capable of rapid growth and the accumulation of large amounts of lipids (Y. Li, Horsman, Wu, Dubois‐Calero, & Lan, ; T. A. D. Nguyen et al, ). The utilization of microalgae in the biofuel production have numerous advantages, such as nonrequirement of arable land, high yield of storage compounds, and utilization of wastewater and waste CO 2 (Chisti, ; Collotta, Champagne, Mabee, & Tomasoni, ; J. P. Kim, Kang, Park, Kim, & Sim, ; Sayre, ). Microalgae have high potential as biodiesel feedstock as they can store neutral lipids in the form of triacylglycerol (TAG), which can be easily converted into biodiesel after transesterification (Zhu, Li, & Hiltunen, ).…”

Microalgae have a high potential to be utilized as feedstock for biofuels because they have high growth rates and do not compromise food production. Commercialized algae-based biofuel production relies on the development of strains with high lipid content. Based on the relatively low density of lipids compared to other cellular components, density gradient centrifugation was used to isolate high lipid content algal strains from Chlamydomonas reinhardtii mutant libraries. The correlation between cell density and lipid content was confirmed by analysis of Nile red fluorescence intensity, total lipids, and total fatty acid methyl ester content. A strain isolated by this screening method had 50% higher lipid content and 7% lower cell density than the parent wild-type strain. Consequently, we demonstrated that screening of algal strains with low cell density via continuous density gradient centrifugation allows simple, rapid, and inexpensive screening for high lipid content strains.
