“…The successful use of suspended free-cells of Nannochloropsis sp. cells and other microalgal species to remove COD from POME has also been reported by several researchers (Ahmad et al 2015;Ammar et al 2018;Hadiyanto et al 2014;Rajkumar and Takriff 2015;Selvam et al 2015;Shah et al 2016). Based on the aforementioned previous reports, the biomass concentration and COD removal efficiency were influenced by POME concentration and type of microalgae species (suspended freecells or immobilized cells) to be used for POME treatment.…”

The use of freely suspended cells of microalgae culture to treat wastewater is of current global interest because of their effective photosynthetic uptake of pollutants, carbon dioxide sequestration, and biomass production for desirable high value-products. Biomass immobilization is a promising option to overcome the harvesting problem that is encountered when using free-cells upon completion of the wastewater treatment process. In this study, Nannochloropsis sp. cells were immobilized in sodium alginate beads to eliminate the harvesting limitation. The microalgal beads were further cultivated in treated palm oil mill effluent (TPOME) for removal of chemical oxygen demand (COD). The effect of POME concentration on COD removal and microalgal cells growth was investigated, respectively. It was found that the maximum biomass concentration of 1.23 g/L and COD removal of 55% from 10% POME were achieved after 9 days. An increment of POME concentration did not cause any improvement to the treatment efficiency due to the inhibitory effect of high initial COD of POME on the biomass concentration and was further responsible for low COD removal. The immobilized cells showed a systematic growth, demonstrating that the beads are biocompatible as immobilization carrier. In conclusion, the immobilized microalgal cells could be a viable alternative technology system for POME treatment as well as biomass production.

Increased interest in renewable, carbon-neutral energy sources makes processing biodiesel from microalgae has become the objective for many researchers and companies. Some kind of wastewater including municipal, industrial and agricultural wastewaters have been identified as alternate growth mediums. Produced water is the largest byproduct of the oil and natural gas extraction process which constitutes of high concentration of pollutants, such as dissolved nitrogen, phosphorus, dissolved organic carbon, heavy metal and monocyclic aromatic compound like BTEX. The purpose of this study is to identify Chlorella sp. potential for producing lipid in artificial produced water. Variations made in this study consist of 0%, 25%, 50%, 75% and 100% volume of artificial produced water to the control Walne medium. The highest specific growth rate and biomass productivity of Chlorella sp. achieved by culture grown in 25% wastewater with a value of 0.225 day−1 and 0.175 g L−1day−1, respectively. The highest lipid yield and productivity in mixed culture of artificial produced water and Walne medium achieved by culture in 25% artificial produced water with value of 0.231 and 40.48 mg.L−1.day−1. C16 and C18 fatty acids which dominated the lipids of Chlorella sp. in all culture variations indicated that the lipid of Chlorella sp. were suitable for producing high quality biodiesel.

“…Data from the literature suggests high efficiency in the use of microalgae for the reduction of contaminants resulting to effluent treatment. It is possible to observe representative values in the removal of mineral salts (Leong et al, 2018;Mohammadi et al, 2018;Ridley et al, 2018;Saavedra et al, 2018), metals (Peng et al, 2017;Saavedra et al, 2018;Shen et al, 2018), pesticides (González et al, 2012), pharmaceutical compounds (Escapa et al, 2017), oils (Ammar et al, 2018), among others.…”

Microalgae are unicellular organisms, photosynthesizers that present cell duplication exponentially and biosorption capacity of nutrients dissolved in water. The objective of this work was to evaluate the capacity of the microalga Pseudokirchneriella subcapitata for bioremediation of metals and salts. In this aspect, the reduction of the metals and salts in the synthetic effluents by the microalga P. subcapitata was evaluated: (T1) culture medium (control); (T2) culture medium contaminated with aluminum chloride; (T3) culture medium contaminated with ferrous sulfate; (T4) culture medium contaminated with zinc sulfate; (T5) culture medium contaminated with the combination of aluminum chloride, ferrous sulfate and zinc sulfate. The bioremediation process was evaluated by comparing culture media with suspended microalgae to a filtrate version of the same medium. Iron and zinc metals, as well as nitrogen and phosphorus salts, showed depleted values in the filtered medium, indicating efficiency in the treatment of water by microalgae. Aluminum content was below the limit of detection in all treatments. The cumulative values in the microalgae biomass were, in descending order: nitrogen, zinc, iron and phosphorus, thus indicating the assimilation of the contaminants in the algal biomass. In addition, high biomass production of the microalgae was observed. The highest production rate was verified in the synthetic effluent with the association of metals, indicating a synergy between contaminants, which was probably responsible for reducing the toxic effect on the microalgae. These results indicated high potential for bioremediation by microalga P. subcapitata, besides the possibility of using algal biomass for biotechnological applications.
