Karst water concocted culture medium which contains high concentration of complex minerals was presumed to support production of microalgae, such as Spirulina sp. (Arthrospira sp.), Chlorella sp., and Nannochloropsis sp. This study aims to evaluate the potential of enriched karst water medium to grow Spirulina sp., Chlorella sp., and Nannochloropsis sp. There were two batches of culture with different treatments of nutrient supplementary; the first was for Spirulina sp. and the second was for Chlorella sp. and Nannochloropsis sp. The results showed that all treatments were suitable for Spirulina sp. with different growth rates. The medium with 20:1 N/P ratio showed the best productivity for Chlorella sp., and 10:1 N/P ratio for Nannochloropsis sp. The pure karst water and all level as the nutrient modified karst water media showed a relatively similar growth rate of Spirulina sp. Furthermore, in the best medium for Chlorella sp. and Nannochloropsis sp. gave increasing density until the end of observation, instead of a death phase of commercial addition batch culture. Generally, modified karst water has the potential to be used as the microalgae growing medium.

The application of reclaimed water has been recognized as the key approach for alleviating water scarcity, while its low quality, such as high nitrogen content, still makes people worry about the corresponding ecological risk. Herein, we investigated the feasibility of removing residual nitrate from reclaimed water by applying Spirulina platensis. It is found that 15 mg/L total nitrogen could be decreased to 1.8 mg/L in 5 days, equaling 88.1 % removal efficiency under the optimized conditions. The deficient phosphorus at 0.5–1.0 mg/L was rapidly eliminated but was already sufficient to support nitrate removal by S. platensis. The produced ammonia is generally below 0.2 mg/L, which is much lower than the standard limit of 5 mg/L. In such a nutrient deficiency condition, S. platensis could maintain biomass growth well via photosynthesis. The variation of pigments, including chlorophyll a and carotenoids, suggested a certain degree of influences of illumination intensity and phosphorus starvation on microalgae. The background cations Cu2+ and Zn2+ exhibited significant inhibition on biomass growth and nitrate removal; thus, more attention needs to be paid to the further application of microalgae in reclaimed water. Our results demonstrated that cultivation of S. platensis should be a very promising solution to improve the quality of reclaimed water by efficiently removing nitrate and producing biomass.

“…Some waste can be utilized as a microalgae culture medium in some previous studies such as liquid waste of palm oil (Mahdi et al 2012), urban liquid waste (Djaghoubi et al 2015), tofu liquid waste (Syaichurrozi and Jayanudin 2016;Simamora et al 2017), and anaerobic processed swine waste (Cheunbarn and Peerapornpisal 2010). Liquid waste of palm oil was used as a culture medium for Spirulina platensis, Nannochloropsis sp, and Chlorella sp.…”

Abstract. Susanty D, Oksari AA. 2020. Growth and secondary metabolites content of chloroform extract of Chlorella sp. and Chlorella sorokiniana cultured on chicken broiler waste media. Nusantara Bioscience 12: 28-32. Intensive chicken broiler farms create waste in the environment. Chicken Broiler Waste (CBW) was used as culture media for Chlorella sp. InaCC M39 and Chlorella sorokiniana InaCC M38 at various concentrations (2, 4, 6, 8, and 10%), and compared to AF6 media. The growth of Chlorella was observed every 48 hours for 10 days by counting the number of cells using a hemocytometer. The chloroform extract of Chlorella sp. and C. sorokiniana were analyzed for their phytochemical content to determine the presence of alkaloids, flavonoids, saponin, steroids, and tannin. The results showed that 2% of CBW media was the best medium for the growth of Chlorella with nitrogen (N), phosphorus (P), and potassium (K) content was 0.01% N; 0.01% P; 0.06% K respectively. The highest specific growth rate of Chlorella sp. on 2% CBW medium was on the 8th day of culture (0.8133) with cell density of 1.6 x 106 cells/mL, while the highest specific growth rate of Chlorella sorokiniana was on the 6th day (0.8907) with cell density of 2.99 x 107 cells/mL. The chloroform extract of the biomass of Chlorella sorokiniana contained steroid and saponin
