“…The strains were cultured in the Zarrouk medium with suboptimal temperatures, nitrogen and phosphoric starvation, and 2% of CO 2 . Neutral lipids contents were increased by the stressors in both of the strains, which could be valuable for the lipid‐based biodiesel generation . The effect of CO 2 and nitrogen sources on the growth and lipid synthesis of Synechococcus subsalsus , a fast‐growing cyanobacterium, was investigated by Setta et al The cyanobacterium was cultured in seawater, enriched with Conway medium.…”

Cyanobacteria are photosynthetic microorganisms which can be found in various environmental habitats. These photosynthetic bacteria are considered as promising feedstock for the production of the third‐ and the fourth‐generation biofuels. The main subject of this review is highlighting the significant aspects of the biofuel production from cyanobacteria. The most recent investigations about the extraction or separation of the bio‐oil from cyanobacteria are also adduced in the present review. Moreover, the genetic engineering of cyanobacteria for improving biofuel production and the impact of bioinformatics studies on the designing better‐engineered strains are mentioned. The large‐scale biofuel production is challenging, so the economic considerations to provide inexpensive biofuels are also cited. It seems that the future of biofuels is strongly dependent to the following items; understanding the metabolic pathways of the cyanobacterial species, progression in the construction of the engineered cyanobacteria, and inexpensive large‐scale cultivation of them.

BACKGROUND Extracellular polymeric substances and microalgae stimulate membrane fouling during harvesting. The objective of the study was to compare the effect of pore formers on TiO2 embedded polyethersulfone mixed matrix membranes (MMMs) to harvest Coelastrella sp. FI69. The study experimented with hydrophilic additive (polyethylene glycol), polyelectrolyte additive (polyethylenimine), inorganic additive (zinc chloride) and charged polymer (sulfonated polyetherether ketone (SPEEK)) as pore formers. RESULTS It was found that SPEEK/TiO2 combination enhanced the hydrophilic property of the PES membrane surface. Also, contact angle value (55.22°) was decreased by 1.38 times that of a neat PES (76.63°) membrane. Morphology studies indicated that the TiO2 particles dispersed well in the PES membrane matrix along with pore formers. The existence of super hydrophilic TiO2 supported the restriction of microalgae cell attachment on the membrane surface. The filtration of alginic acid sodium solution analysis showed that PES/SPEEK/TiO2 and PES/PEG/TiO2 membranes support higher flux with minimal fouling percentage. Microalgae filtration studies indicated that synergistic effect of both SPEEK and TiO2 on PES membrane exhibited higher water recovery percentage of 96% and equilibrium flux of 66 L m‐2 h‐1. CONCLUSION Fouling propensity is significantly reduced in modified membranes. Future research on scale‐up of membranes for further microalgae dewatering applications is recommended. © 2017 Society of Chemical Industry

“…Such climatic conditions can be found in the Mediterranean region . Due to their ability to accumulate high amounts of lipids (up to 70%), which is the crucial component for biodiesel production, microalgae have emerged as a promising feedstock for biodiesel production . Biodiesel, a biodegradable and nontoxic biofuel, is an excellent substitute for fossil‐fuel based diesel, i.e.…”

The environmental sustainability of microalgae‐to‐biodiesel production systems was examined at open (outdoor) and closed (indoor, using artificial light and temperature control) raceway ponds in a Mediterranean climate (southern Greece). Spirulina platensis and Nannochloropsis sp. species were considered, with the latter having a slightly better environmental performance. In terms of energy efficiency, large cumulative energy demand (CED) values were observed, while the energy return‐on‐investment (EROI) ratio was well below 3 in all cases, indicating that, with current technology, algae‐to‐biodiesel systems have not reached sustainability yet. The impact on land use was minimal, as nonarable land was used. Shallow‐pond cultivation systems are energy intensive, especially the closed ones, and therefore were found to be associated with high environmental footprints. In all cases, the main environmental hotspot was, by and large, the electricity consumption from the Greek fossil‐fuel depended energy mix (90%). Pellet, a process co‐product, largely reduced the total environmental footprint by up to ~47%, which highlights the importance of co‐product valorization. Closed systems exhibited significantly higher environmental footprints compared to open ones, due to the large energy inputs for artificial solar irradiation and for indoor temperature control. In all the cases examined, the microalgae‐to‐biodiesel production system's environmental footprint was higher than that of fossil diesel (i.e. petrodiesel), indicating that ample room exists to improve their environmental performance. A sensitivity analysis revealed that the introduction of renewable energy solely to cover for electricity needs substantially improves environmental sustainability and could render microalgae‐to‐biodiesel systems an environmentally friendlier solution than petrodiesel. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd
