“…6a, b. It could be seen that algae preferred to assimilate ammonium before nitrate, which was in accordance with the previous papers (Li et al 2011;Su et al 2012). The answer for ammonium preference is in the different nitrogen uptake mechanisms of microalgae that differ regarding nitrogen sources.…”

The feasibility of alginate-immobilised Chlorella sorokiniana for nitrate and ammonium removal from drinking water in regard to carbon source effects was studied in this paper. Three different natural carbon sources were tested in batch experiments with nitrate as nitrogen source: sucrose, grape juice and acacia honey. The nitrate removal efficiencies achieved at 50 mg/L of initial nitrate concentration under sucrose, grape juice and acacia honey were 93, 99 and 94 %, respectively. At 100 mg/L of nitrate, comparable efficiencies were obtained after approximately 3 days, whilst for acacia honey at 50 mg/L, it took only 2 days of cultivation and 3 days for the other two carbon sources. Grape juice and acacia honey showed better performances than sucrose, which must be linked to their chemical compositions. The study of the impact of biosorbent quantity on nitrate removal efficiency showed that sufficient nitrate removal efficiencies could be achieved with a beads/water ratio of 1:6.7 (v/v) or smaller. In addition, the beads' ages significantly impacted the nitrate removal. The removal of ammonium was studied in the presence of nitrate with acacia honey as carbon source.At the highest concentrations being tested (ammonium-30 mg/L and nitrate-50 mg/L), ammonium was completely removed in \3 days and nitrate by 81 % in 4 days, whereby the suitable beads/water ratio was 1:5. The priority of ammonium assimilation was noticed when compared to nitrate. According to the results, the alginateimmobilised C. sorokiniana represents a promising tool for the removal of nitrogen from drinking water sources.

“…Availability and cost effectiveness of municipal wastewater for microalgae growth need no explanations [30,51]. For removal of phosphorus and nitrogen from municipal wastewater, microalgal cultivation is being most extensively applied [52][53][54][55]. Lu et al [56] reported that cultivating microalgae with municipal wastewaters is not only feasible for the biodiesel production, but also helps in removing nitrogen and phosphorus.…”

“…Results were average lipid contents of 27 % of dry weight of biomass. Various other food industrial/agricultural residues/wastes have been employed for maximum microalgal biomass and biodiesel production like rice straw hydrolysate being utilized for growing Chlorella pyrenoidosa [54], orange peels extract for Chlorella vulgaris [59] and sugarcane bagasse for Scenedesmus acutus [60].…”

Pond-grown microalgae have been considered as feedstocks for production of biodiesel. Various natural habitats and man-made environments can be exploited to cultivate microalgae without utilizing arable land which is already decreasing due to urbanization and industrial development. Suitable temperature, solar illumination and availability of phosphorus and nitrogen-rich organic wastes result in algal blooms in stagnant water and river bank's associated pools in many regions including Pakistan.

“…Under nitrogen stress conditions, many algae alter their lipid biosynthetic pathways resulting in the formation and accumulation of neutral lipids (Li et al, 2011). Biomass productivity depends on the feed composition and time needed to cultivate microalgal cells.…”
