“…in CO 2 -enriched urban wastewater and biomass productivity ranging from 0.138 to 0.227 g L -1 day -1 was recorded (Table 3). Lizzul et al (2014) observed that Chlorella sorokiniana produced 0.22 g L -1 of biomass in municipal wastewater centrate and supplementation of external CO 2 increased biomass production to 0.33 g L -1 . The reports dealing with nutrient removal potential and biomass production in wastewaters are summarized in Table 4.…”

Discharge of untreated domestic and industrial wastewater into aquatic bodies is posing a serious eutrophication threat, leading to a slow degradation of the water resources. A number of physical, chemical and biological methods have been developed for the treatment of wastewaters; among these, the use of microalgae is considered as a more eco-friendly and economical approaches. Microalgae are versatile organisms which perform multiple roles in the environment-bioremediation of wastewater, gleaning of excess nutrients and in turn, generate valuable biomass which finds applications in the food, biofuel and pharmaceutical industries. They are currently being utilized to reduce the high nutrient load (especially N and P) from wastewaters, which fulfill the growth requirements of microalgae, making it a suitable cultivation medium for biomass production. The present review represents a comprehensive compilation of reports on microalgal diversity of wastewaters, followed by a critical overview of their utilization, suitability and potential in bioremediation vis-a-vis biomass production. This review also emphasizes the superiority of polyalgal and consortial approaches in wastewater treatment, as compared to the use of unialgal inocula, besides providing useful pointers for future research needs in this area.

Discharging waste without removing harmful compounds can lead to serious environmental and health issues. Despite of the high content of pollutants, wastewater environment can become an ideal condition for the growth of several microorganisms. Some species of microalgae have been found living in palm oil mill effluent (POME), making it suitable to be used in biological treatment. However, the ability of microalgae to grow and its composition characteristics in synthetic media are unknown. Therefore, this study evaluated the growth characteristics and biochemical productivity of Chlorella sorokiniana UKM3, Coelastrella sp. UKM4 and Chlorella sp. UMACC324, which had been previously isolated from POME. Bold's Basal Media (BBM) was used as the medium for cultivation. The experimental works were performed in a lab-scale photobioreactor at room temperature under continuous illumination for 14 days. From this study, Coelastrella sp. UKM4 showed the highest value of growth rates (0.52±0.

Walaupun kandungan bahan pencemar adalah tinggi, air sisa boleh menjadi habitat yang ideal bagi pertumbuhan sesetengah spesis mikroorganisma. Beberapa spesies mikroalga telah dijumpai hidup dalam effluen kilang minyak sawit (POME). Ini menjadikan spesis mikroalga tersebut sesuai digunakan dalam proses rawatan sisa secara biologikal. Walau bagaimanapun, keupayaan mikroalga untuk bertumbuh dan ciri-ciri komposisinya didalam media sintetik adalah tidak diketahui. Oleh itu, kajian ini dijalankan untuk menilai ciri-ciri pertumbuhan dan produktiviti biokimia bagi Chlorella sorokiniana UKM3, Coelastrella sp.

“…symporter proteins responsible for its metabolism could be reduced (Tanner 2000;Zheng et al 2013). The explanation for pH rising when using nitrate as nitrogen source may be found in the production of hydroxyl ions during nitrogen metabolism; furthermore, the uptake of CO 2 from dissolved bicarbonate during photosynthesis could also be reflected in pH increase under nitrate growth conditions (Lizzul et al 2014). Besides the type of nitrogen source, the pH value is also connected with the initial concentration of the chosen nitrogen source.…”

“…Current studies on C. sorokiniana included investigations on its performance for nutrients removal from polluted waters (de-Bashan et al 2004;Lizzul et al 2014), some focused on its potential for biofuel production (Zheng et al 2013), and others examined growth conditions (Kim et al 2013b;Kumar and Das 2012). However, the application of C. sorokiniana for wastewater treatment processes was only efficiently implemented in rare studies.…”

“…A combination of C. sorokiniana and a growth-promoting bacterium A. brasilense, co-immobilised in alginate beads, was also developed to remove phosphorus and nitrogen from wastewater (de-Bashan et al 2004;Hernandez et al 2006). As C. sorokiniana is, according to above-mentioned papers, a suitable strain for water treatment and has the capability of utilising multiple carbon sources even under mixotrophic conditions (Lizzul et al 2014;Qiao et al 2009), it was the proper choice for the present study.…”

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.
