“…This corroborates previous results showing on the application of a mixed culture of microalgae (Scenedesmus and Chlorella spp.) for the treatment of TW in a sequencing batch reactor [ 28 ]. Nevertheless, further studies should verify whether during the recovering/adaptation time the microalgae develop cellular strategies to face the toxicity of the TW, or whether other microorganisms, such as autochthonous bacteria in the TW, played a role in the biodegradation of part of the recalcitrant and hazardous compounds in the TW facilitating the growth of the microalgae.…”

“…Colour and ammonia removal by C. vulgaris in a high rate algae pond (HRAP) fed on undiluted TW reached up to 47% and 45% respectively after 12 days of cultivation in batch [19]. Nonetheless, few experiences are reported about long term cultivation of microalgae in raw TW and mostly concern the association of microalgae with other physicochemical or microbial processes [27][28][29].…”

The treatability of seven wastewater samples generated by a textile digital printing industry was evaluated by employing 1) anammox-based processes for nitrogen removal 2) microalgae (Chlorella vulgaris) for nutrient uptake and biomass production 3) white-rot fungi (Pleurotus ostreatus and Phanerochaete chrysosporium) for decolorization and laccase activity. The biodegradative potential of each type of organism was determined in batch tests and correlated with the main characteristics of the textile wastewaters through statistical analyses. The maximum specific anammox activity ranged between 0.1 and 0.2 g N g VSS-1 d-1 depending on the sample of wastewater; the photosynthetic efficiency of the microalgae decreased up to 50% during the first 24 hours of contact with the textile wastewaters, but it improved from then on; Pleurotus ostreatus synthetized laccases and removed between 20–62% of the colour after 14 days, while the enzymatic activity of Phanerochaete chrysosporium was inhibited. Overall, the findings suggest that all microbes have great potential for the treatment and valorisation of textile wastewater after tailored adaptation phases. Yet, the depurative efficiency can be probably enhanced by combining the different processes in sequence.

“…Growth determination by optical density (OD) method is well-known to be used in the microorganism community since it indicates measuring the suspended biomass present in the liquid sample ( Kumar et al 2018) . The growth curves of the MC, collected from three different water resources, were demonstrated in Fig.…”

Microalgae are photoautotrophic microorganisms that can be grown in a wide variety of water environments. They are the most promising biodiesel source, with the potential to replace fossil diesel. In this study, microalgae samples were collected from the brackish water environment of three locations in Rayong province, Thailand including Phra Chedi Klang Nam (PKC), Noen Kho Canal (NKC), and Raksamae Bridge (RSM), and induced to form multi-algae communities or microalgal consortia (MC). All consortia were cultured and analyzed for their ability to produce biomass and lipid. The result was found that the biomass concentration of MC-RSM was 0.65 ± 0.05 mg.L-1, which is higher than 1.2 and 1.5-times of MC-PCK and MC-NKC, respectively. The most common microalgae species found under all cultures were green algae (Chlorophyta) and diatom (Bacillariophyta), and the dominant species was the green algae, Chlorella sp. The lipid content of all samples ranged from 28.07 ± 0.60 to 33.21 ± 0.79% of dry weight, and the highest value was noticed in the MC-RSM sample. The fatty acid composition of fatty acid methyl ester (FAME) was also evaluated as feasibility for biodiesel production. FAME profiles of each sample showed high amounts of saturated fatty acids (SFAs) ranging from 67.82%-71.31% of total fatty acids. The majority of the SFAs in all were palmitic acid (C16:0) followed by myristic acid (C14:0, and stearic acid (C18:0). Therefore, all microalgal consortia showed great fatty acid profiles and these have the potential for use as feedstock for biodiesel production.

Bioremediation capacity of azo dyes in simulated characteristics of textile wastewater from the microalgae Chlorella vulgaris was determined. The evaluation of the percentage of removal of Erionyl Turquoise was carried out through the measurement of the change of the final and initial absorbance during 15 days. The microalgae were exposed to different concentrations of the azo dye (30, 70 y 130ppm) and an initial pH of 9. Concurrently, the behavior of the microalgae C. vulgaris was compared with a natural pH of 8.3. The highest percentage of removal was 91.7% and this was obtained with a concentration of 70 ppm and an initial pH of 9, while the lowest percentage of removal was 51.5% with a concentration of 130 ppm of the Erionyl Turquoise and an initial pH of 9. In this way, it can be established that the microalgae C. vulgaris has a considerable ability to remove azo dyes under some characteristics of textile wastewater.
