“…Nutrient additions were found to significantly affect growth and final biomass of P. tricornutum growing on POME. P. tricornutum could grow well on 30% POME (0.66 ± 0.12 day −1 ) without adding external nutrients, likely due to the favorable N/P ratio being close to Redfield (13:1) as found in a previous study (Nur et al 2016;Hadiyanto et al 2017). However, this growth rate was significantly lower than the artificial f/2 medium, which might be due to nutrient speciation issues in the treated POME which contains relatively high organic nitrogen (Onyla et al 2001).…”

“…The total concentration of phenolic compounds in POME can reach up to 303 mg L −1 as demonstrated before (Neoh et al 2013), yet unfortunately these compounds were not measured during our experiments. Marine microalgae such as Dunaliella salina and P. tricornutum were described to be more sensitive to phenolic compounds from digested POME than freshwater algae such as Chlorella vulgaris (Nur et al 2016;Duan et al 2017). Overall, a 30% POME fraction was found to be most suitable to be used as growth medium for P. tricornutum for all subsequent experiments in this study.…”

Sulfated exopolysaccharide production and nutrient removal by the marine diatom Phaeodactylum tricornutum growing on palm oil mill effluent

et al. 2019

Palm oil mill effluent (POME) is the major source of environmental hazard in palm oil industry. Yet, due to its high nutrient content, POME may offer opportunities for the growth of algae as a source of value-added compounds such as sulfated extracellular polysaccharide (sEPS) while simultaneously removing valuable nutrients such as phosphate. The aim of this paper was to evaluate growth, total sEPS production, and nutrient removal by the diatom Phaeodactylum tricornutum grown on POME under a range of experimental conditions (temperature, salinity, supplementation of extra nutrients). Phaeodactylum tricornutum was found to grow well on a range of POME concentrations, with 30% POME as optimum concentration. Nitrate and urea addition enhanced both growth rate and final biomass, whereas phosphate significantly stimulated growth only at low temperature. Box-Behnken response surface methodology revealed that interactions between temperature and salinity, and between temperature and urea influenced sEPS production. The highest total sEPS (140 mg L −1) concentration was recorded at 25°C, 2.6% salinity, and 100 mg L −1 urea addition. Our study shows that POME wastewater, supplemented with urea at relatively high temperatures, can be considered as a potential medium for P. tricornutum to replace commercial nutrients while producing high amounts of sEPS and removing almost 90% of phosphorous from the wastewater.

“…Conversely, continuous cultivation is not easily applicable in large-scale systems since the operation and the maintenance need special equipment and skilled labor, and the cost of the construction is still high (Lehr and Posten 2009;Fernandes et al 2015). Finally, several studies demonstrated the utilization of POME by using dilution and or synthetic fertilizer supplementation (Sari et al 2012;Nur et al 2016). However, these reports were not focused on the optimization of C-PC productivity.…”

Enhancement of C-phycocyanin productivity by Arthrospira platensis when growing on palm oil mill effluent in a two-stage semi-continuous cultivation mode

et al. 2019

View full text Add to dashboard Cite

Palm oil mill effluent (POME) is well known as agricultural wastewater that has a high potential as a medium for microalgal growth due to its high macro-and micronutrient content. The cyanobacterium Arthrospira platensis is considered as a species with a high C-phycocyanin (C-PC) content which is important for fine chemical and pharmaceutical applications. However, cultivation of A. platensis on POME to produce economically feasible amounts of C-PC has not been well explored. For this, environmental, nutritional, and cultivation modes (batch, semi-continuous) were varied to optimize C-PC productivity when cultivated at various POME concentrations. Arthrospira platensis was found to grow well on POME. Highest biomass and C-PC concentrations were found on 30-100% POME. Central composite rotatable design (CCRD) response surface methodology demonstrated that C-PC productivity was influenced by urea addition at the optimum salinity. The highest C-PC productivity was found on 100% POME during semi-continuous cultivation, while the addition of phosphorus and urea did not significantly improve C-PC productivity. By applying semi-continuous cultivation with 50% POME at the first stage and 100% POME at the second stage, a similarly high C-PC productivity (4.08 ± 1.3 mg L −1 day −1) was achieved as compared with (artificial) Zarrouk medium during batch cultivation. We conclude that, when using a two-stage semi-continuous cultivation process, A. platensis can produce economically feasible amounts of C-PC when cultivated on 100% POME.

“…The higher differences of the temperature between inside and outside the cell, that was resulted from fast repeating frequency (2.45 GHz), makes the walls more easily destroyed [41]. Previous research also reported that microwave irradiation on the hydrolysis of the algal biomass gave shorter time compared to conventional hydrolysis [42]. However, the biomass content was lower compared to previous research.…”

Indonesia is known as the largest oil palm producer in the world. However, along with the production, it generates wastes and pollution that caused the environmental problem in surrounding areas. Previous researchers reported that the high palm oil mill effluent (POME) concentration inhibited microalgae growth. However, the inhibition factor was not clearly explained by using kinetic model. This study presents kinetic models of Botryococcus braunii (B. braunii) cultivated on POME wastewater under different turbidity condition. Results showed that the growth model of Zwietering was closely suitable with experimental results. It was found that B. braunii was able to consume organic carbon from the POME wastewater on the logarithmic model. A modified kinetic model of Monod Haldane described the influence of turbidity and chemical oxygen demand on the cultivation. Turbidity of POME medium inhibited the growth rate at KI 3.578 and KII 179.472 NTU, respectively. The Lipid (39.9%), and carbohydrate (41.03%) were found in the biomass that could be utilized as biofuel source.
