“…For the past two years, collapse in the oil prices imposes large economic pressure on biofuel production (Cate and Ball, 2016). In order to make microalgal biofuels commercially feasible and practically viable, microalgal biomass must be processed similar to petroleum refinery for extracting multiple products in addition to biofuel, in a biorefinery concept (Maurya et al, 2016). Many up-and downstream processes have successfully been integrated during the conversion of microalgal biomass.…”

The efficiency of cyanobacterial strains as biodiesel feedstock varies with the dwelling habitat. Fourteen indigenous heterocystous cyanobacterial strains from rice field ecosystem were screened based on growth kinetic and fuel parameters. The highest biomass productivity was obtained in Nostoc punctiforme MBDU 621 (19.22 mg L-1 d-1) followed by Calothrix sp. MBDU 701 (13.43 mg L-1 d-1). While Lipid productivity and lipid content was high in Nostoc spongiaeforme MBDU 704 (4.45 mg L-1 d-1 and 22.5 % dwt) followed by Calothrix sp. MBDU 701 (1.54 mg L-1 d-1 and 10.75 % dwt). Among the tested strains, Nostoc spongiaeforme MBDU 704 and Nostoc punctiforme MBDU 621 were selected as promising strains for good quality biodiesel production by Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) and Graphical Analysis for Interactive Assistance (GAIA) analysis.

Iron chlorosis represents a physiological phenomenon with negative impact on the quality and quantity of grape production in the vineyards. The bicarbonates are considered to be the main group of compounds which immobilize the iron in the soil in forms not assimilable by the plants. The grape production in conditions of iron deficiency can be improved significantly by applying foliar fertilizers. The best result in mitigating the effects of iron deficiency were obtained by the application of the fertilizers which, in addition to a complex mineral composition, also have a content of organic matter in the form of humic substances or protein hydrolysate.

“…Recently, Mishra and Mohanty [57] reported the comprehensive characterization of lipid-extracted microalgae biomass (LEMB) by biochemical, thermo gravimetric analysis (TGA), Fourier transform infra-red (FTIR), and carbon, hydrogen, nitrogen, sulfur (CHNS) analysis and its utilization for the production of value-added products such as growth promoter, feedstock for biogas, bioethanol, and bio-oil production [57]. According to recent studies, the generated amount of lipid-extracted microalgae biomass is estimated to be thrice the amount of biodiesel produced and it is assumed that microalgal biomass extraction yields 25% oil [59]. Even after lipid extraction for biodiesel production, LEMB contains a considerable amount of nutrients such as carbohydrates, proteins, nitrate, phosphates, glucose, arabinose, xylose and other micronutrients [58,59].…”

Even after lipid extraction for biodiesel production, LEMB contains a considerable amount of nutrients such as carbohydrates, proteins, nitrate, phosphates, glucose, arabinose, xylose and other micronutrients [58,59]. In order to achieve the zero-waste approach in a microalgae refinery, Mishra and Mohanty [57] have shown that the comprehensive characterization of LEMB derived from wastewater-treated microalgae (wastewater as a growth medium) was found to contain carbon 47.04%, hydrogen 7.29%, nitrogen 6.6%, sulfur 0.16%, and oxygen 38.91%, while the elemental composition of the BG11-derived LEMB contained carbon 50.18%, hydrogen 7.51%, nitrogen 6.3%, sulfur 0.11%, and oxygen 35.9%, respectively.…”

Cultivation of Oily Microalgae for the Production of Third-Generation Biofuels

Biofuel production by oleaginous microalgae is a promising alternative to the conventional fossil fuels. Many microalgae species have been investigated and deemed as potential renewable sources for the production of biofuel, biogas, food supplements and other products. Oleaginous microalgae, named for their ability to produce oil, are reported to store 30–70% of lipid content due to its metabolic properties under nutrient starvation conditions. This review presents the assortment of the research studies focused on biofuel production from oleaginous microalgae. The new methods and technologies developed for oleaginous microalgae cultivation to improve their biomass content and lipid accumulation capacity were reviewed. The production of renewable, carbon neutral, bio-based or microalgae-based transport fuels are necessary for environmental protection and economic sustainability. Microalgae are a significant source of renewable biodiesel because of their ability to produce oils in the presence of sunlight more efficiently than that of crop oils. This review will provide the background to understanding the bottlenecks and the need for improvement in the cultivation or harvesting process for oleaginous microalgae.
