“…However, the highest (37.9 ± 7.4 wt%) average monthly biomass lipid content which occurred in June 2014 (NZ winter) in the EHRAP coincided with the lowest mean monthly ammonia concentration (2 ± 1 mg/L) in the pond (Table 2). It has been shown that the lipid content of algae/WWT HRAP biomass is highly dependent on algal species, temperature, sunlight, growth phase and nutrient concentration in culture medium (Drira et al, 2016;Mehrabadi et al, 2016;Rodolfi et al, 2009;Xu et al, 2016). The highest biomass lipid content in winter and when the ammonia concentration was at the lowest average level (in both influent and effluent) implies that nutrient concentration, particularly ammonia concentration, is the main influencing factor which was consistent with the literature (Eustance et al, 2016).…”

“…Among these, microalgal oils have come forward as the most promising feedstock for biofuel production. Several studies have reported the potential of various microalgal species for the production of biodiesel, including Chlorella protothecoides (Nan et al 2015), Nannochloropsis (Hindarso et al 2015) and mixed algal cultures (Soydemir et al 2016), using both fresh and wastewater as source of nutrients (Chiu et al 2015;Drira et al 2016).…”

The present study was focussed on selection of fast-growing microalgae with higher lipid content using cheaper growth media, aimed to reduce the cost of algal biomass production. Samples were collected from 40 different sites from fresh and wastewater bodies. Based on morphological differences, two microalgae (SSG and SA) from wastewater and three (OP, DFM and JRC) from fresh water habitat were selected for further characterization. The specific growth rates (g Day −1 L −1) of the OP, DFM, JRC, SA and SSG were found to be 0.614, 0.638, 0.734, 1.06 and 1.02, respectively, whereas the doubling time (T d) was shown to be as 39.30, 36.48, 22.08, 12.24 and 12.98 h, respectively, when cultured without controlled temperature and CO 2 supply, in a locally designed photobioreactor. All five microalgae shown considerable growth at a range of pH 6.0-9.0 with a peak activity within pH range 7.5-8.5. The OP, DFM and JRC contained 27%, whereas SSG and SA shown 39% lipid content. The phylogenetic analyses based on the 18S rRNA gene sequence have shown that studied microalgal strains may be novel species.

“…In the attempt to find a successful algal strain for high ammonia tolerance there are currently several species under consideration around the world (Grzebyk et al 1998;Indarti et al 2015;Udom et al 2013;Zhang et al 2013;Abdelaziz et al 2014;Drira et al 2016;Passos et al 2016;Ruiz-Martinez et al 2012;Canedo-López et al 2016;Dahmani et al 2016;Franchino et al 2016;Kumari et al 2016;Montemezzani et al 2016;Pereira et al 2016).The selected strains are inoculated onto a polystyrene sterile nonpyrogenic 24-well flat bottom culture cluster containing synthetic wastewater. The synthetic wastewater may be a modification of BG11 media obtained by adding a different concentration of NH 4 Cl.…”

Excessive microalgal blooms can be caused by waste disposal into natural water bodies resulting in the destruction of aquatic life. However,, microalgae are also known to efficiently remediate pollutants. After the treatment of wastewater, microalgae absorb specific nutrients and can enhance the production of bioproducts. Growing microalgae as an alternative to wastewater treatment and bioproduct production has received considerable attention due to its rapid growth rate, efficient waste removal, tolerance to stress conditions and ability to accumulate valuable products. In addition, these microorganisms have a high photosynthetic rate of CO2 fixation, oxygen production and need no arable land for their cultivation. Nevertheless, in spite of these theoretical advantages, the issues surrounding the re-use of naturally existing microalgal strains need further exploration in respect to their isolation, identification and lab growth under stress conditions. The true potential of microalgae regarding wastewater treatment and energy has yet to be fully developed. The current cultivation system does not seem to be economically feasible as most of the strains used are commercially purchased. Indigenous microalgae could be the possible answer. Ammonia, one of the major constituents of most wastewaters, contributing to odor, taste, toxicity, and eutrophication is of utmost concern. The present review focuses on the growth of microalgae under high stress of ammonia in wastewater media. It also aims to present a clear-cut methodology for the isolation of microalgae from its indigenous habitat, its growth strategy under different trophic modes of nutrition, nutrient uptake, lipid, and fatty acid production. In addition, some solutions to the problem of how to make microalgae cost-effective and more sustainable are discussed in detail.
