Formation of disinfection byproducts from accumulated soluble products of oleaginous microalga after chlorination

Yu Liu, Qiao Zhang, Yu Hong

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 6, doi: 10.1007/s11783-017-0938-2

Abstract: When microalgae are simultaneously applied for wastewater treatment and lipid production, soluble algal products (SAP) should be paid much attention, as they are important precursors for formation of disinfection byproducts (DBPs), which have potential risks for human health. sp. HQ is an oleaginous microalga that can generate SAP during growth, especially in the exponential phase. This study investigated the contribution of SAP from sp. HQ to DBP formation after chlorination. The predominant DBP precursors from SAP were identified with the 3D excitation-emission matrix fluorescence. After chlorination, a significant reduction was observed in the fluorescence intensity of five specific fluorescence regions, particularly aromatic proteins and soluble microbial by-product-like regions, accompanied with slight shifting of the peak. The produced DBPs were demonstrated to include trihalomethanes and haloacetic acids. As the algal cultivation time was extended in wastewater, the accumulated SAP strengthened the formation of DBPs. The trend for DBP formation was as follows: chloroform>dichloroacetic acid>trichloroacetic acid.

Abstract: A promising microalgal strain isolated from fresh water, which can grow both autotrophically on inorganic carbon under lighting and heterotrophically on organic carbon without lighting, was identified as sp. USTB-01 with the phylogenetic analysis based on 18S ribosomal ribonucleic acid (rRNA) gene sequences. In the heterotrophic batch culture, more than 20.0 g·L of cell dry weight concentration (DWC) of sp. USTB-01 was obtained at day 5, and which was used directly to seed the autotrophic culture. A novel fermentor-helical combined photobioreactor was established and used to cultivate sp. USTB-01 for the fixation of carbon dioxide (CO ). It showed that the autotrophic growth of sp. USTB-01 in the combined photobioreactor was more effective than that in the fermentor alone and the maximum DWC of 2.5 g·L was obtained at day 6. The highest CO fixation of 95% appeared on day 1 in the exponential growth phases of sp. USTB-01 and 49.8% protein was found in the harvested microalgal cells.

Comparison of growth and lipid accumulation properties of two oleaginous microalgae under different nutrient conditions

Qiao ZHANG,Yu HONG

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 5,   Pages 703-709 doi: 10.1007/s11783-014-0649-x

Abstract: This study compared the growth and lipid accumulation properties of two oleaginous microalgae, namely, sp. LX1 and sp. HQ, under different nutrient conditions. Both algal species obtained the highest biomass, lipid content and lipid yield under low-nutrient conditions (mBG11 medium). The biomass, lipid content and lipid yield of sp. LX1 were 0.42 g·L , 22.5% and 93.8 mg·L , respectively. These values were relatively higher than those of sp. HQ (0.30 g·L , 17.1% and 51.3 mg·L , respectively). These algae were then cultivated in an SE medium that contained more nutrients; as a result, the biomass and lipid yield of sp. LX1 reduced more significantly than those of sp. HQ. Opposite results were observed in lipid and triacylglycerols (TAGs) contents. The cell sizes of both algal species under low-nutrient conditions were larger than those under high-nutrient conditions. sp. HQ cells did not aggregate, but sp. LX1 cells flocculated easily, particularly under low-nutrient conditions. In summary, low-nutrient conditions favour the growth and lipid production of both algae, but sp. LX1 outperforms sp. HQ.
