“…With 4% loss by transesterification, a maximum of 215 tons ha −1 year −1 of biodiesel can be produced. It is important to note that a recent study on Scenedesmus accuminatus using open and polyhouse raceway ponds estimated around 2.1 tons ha −1 year −1 , which is times lower than the theoretical maximum [13]. Another study with Chlorella sp.…”

Despite over a century of research, the various applications of microalgae have only been realized only since the 1940s. With a repertoire of valuable products like biodiesel, astaxanthin, canthaxanthin, lutein, β-carotene, phycocyanin, chlorophyll a, polyunsaturated fatty acids, exopolymeric substance (EPS), and biohydrogen, the commercial importance of microalgae and demand for its product is gaining increasing attention. However, successful transition of the synthesis of microalgal products from laboratory to industries has yet to be realized, even after over 70 years of extensive research. This failure of commercial success of microalgal products can be attributed to the lack of understanding of the physiological role of the products and biological constraint placed by the bioenergetics and physiology, which has been largely ignored. This chapter focuses on the physiological limitations behind synthesis of microalgal products, highlights the crucial unknowns behind the role and synthesis of these products, and hints strategies to overcome the limitations to realize the commercial dream of microalgal products.

“…The study was conducted in four numbers of 40,000 L capacity raceway ponds by Bagchi et al (2019). In another study by us at the same geographical location, it was observed that Scenedesmus accuminatus organism produced a biofuel yield of 2.14 tons ha −1 year −1 in open raceway pond batch cultivation (Koley et al, 2019). However, contrary to this Zhang et al (2018) reported a comparatively lower biofuel yield of 0.79 tons ha −1 year −1 algal biofilm raceway ponds.…”

“…Compared to the photobioreactors, raceway ponds are generally preferable for large-scale algal biomass production due to the significantly less capital investment and lower maintenance cost, utilization of wasteland or barren lands, and easy operation techniques (Chisti, 2008). It is also an essential factor that the microalgal cultivation inside the raceway ponds requires the optimum stirring for continuous or semi-continuous mixing to recirculate the microalgal culture (Chisti, 2016;Koley et al, 2019). However, there are many limitations of raceway pond culture of microalgae.…”

The two major bottlenecks faced during microalgal biofuel production are, (a) higher medium cost for algal cultivation, and (b) cost-intensive and time consuming oil extraction techniques. In an effort to address these issues in the large scale set-ups, this comprehensive review article has been systematically designed and drafted to critically analyze the recent scientific reports that demonstrate the feasibility of microalgae cultivation using wastewaters in outdoor raceway ponds in the first part of the manuscript. The second part describes the possibility of bio-crude oil production directly from wet algal biomass, bypassing the energy intensive and time consuming processes like dewatering, drying and solvents utilization for biodiesel production. It is already known that microalgal drying can alone account for ∼30% of the total production costs of algal biomass to biodiesel. Therefore, this article focuses on bio-crude oil production using the hydrothermal liquefaction (HTL) process that converts the wet microalgal biomass directly to bio-crude in a rapid time period. The main product of the process, i.e., bio-crude oil comprises of C16-C20 hydrocarbons with a reported yield of 50–65 (wt%). Besides elucidating the unique advantages of the HTL technique for the large scale biomass processing, this review article also highlights the major challenges of HTL process such as update, and purification of HTL derived bio-crude oil with special emphasis on deoxygenation, and denitrogenation problems. This state of art review article is a pragmatic analysis of several published reports related to algal crude-oil production using HTL technique and a guide towards a new approach through collaboration of industrial wastewater bioremediation with rapid one-step bio-crude oil production from chlorophycean microalgae.

“…For drying experiments, C. minutissima was cultivated in raceway ponds with volumetric capacity of 40,000 L each (14 × 4 × 0.75 m). Before cultivation in raceway ponds, the selected microalga was scaled-up in the UZn medium (Koley, Mathimani, Bagchi, Sonkar, & Mallick, 2019), and was acclimatized to the outdoor condition as detailed in Sonkar, Deb, & Mallick (2020). The raceway ponds were operated at 30 cm of culture depth with a corresponding culture volume of 16000 L. Harvesting of the microalgal biomass was carried by pH-induced flocculation using NaOH at pH 12 for 12 h following Koley, Prasad, Bagchi, & Mallick (2017).…”

Drying of microalgal slurry is one of the important steps of downstream processing which faces several technical challenges for cost-effective biodiesel production. In this investigation, drying of C. minutissima was carried out by a single rotary drum dryer with varied drum surface temperature and rotational speed. Application of machine learning tool classified the range of residual moisture content to be <10% (wet biomass) for high lipid recovery with an accuracy of 97%. Based on the drying time, lipid recovery, and energy consumption, drum drying at 80°C drum surface temperature with 0.3 rpm depicted ¿90% lipid recovery as compared to the bone-dried biomass. The energy consumption of 7.328 kWh for 1 kg of dried biomass was recorded with profoundly lower drying time, thus could be recommended for drying of the microalgal slurry at industrial scale.
