Biomass productivity of Chlorella vulgaris cultivated in fish and dairy cattle wastewaters

The biomass productivity and nutrient composition of microalgae, such as Chlorella vulgaris, depend on the cultivation process content growth media. Thus, in this study aimed to investigate C. vulgaris cultivated fish dairy cattle wastewaters. Thirty wastewater samples (2.5 L) were collected from system production. Microalgae Erlenmeyer flasks containing 10 mL microalgae 1,790 under constant light 5,000 lux for 16 days at 25 ± 2.0 °C. Wastewater differed composition. Biomass was 47 % higher (P<0.0001) than wastewater, reaching 67.61 g m?3 day?1 (dry matter basis, DM) when compared by Student’s t-test (P<0.05). Cultivation media also had an effect chemical grown crude protein ash contents (359.6 kg?1 DM 230.4 DM, respectively), whereas nitrogen-free extract (347.8 DM). Crude fat did not vary greatly (mean 313.15 pH (8.0 – 8.7) ammonia concentration (0.07 0.4 mg L?1) stable throughout 16-day experimental period. In increased up (6.3 8.9) fourth day remained thereafter, (24.3 28.7 eighth then it declined (2.1 L?1). successfully both wastewaters, but wastewater.
