Chlorella vulgaris and Arthrospira platensis growth in a continuous membrane photobioreactor using industrial winery wastewater

The aim of the study is to determine the effects of Bentagran on growth and oxidative effects to Chlorella vulgaris and Arthrospira platensis and to evaluate the herbicide toxicity on primary producers of aquatic ecosystems. The decrease in both biomass accumulation and chlorophyll-a content in a dose-dependent manner were observed in both organisms exposed to different Bentagran concentrations (for C. vulgaris 60–960 µg mL−1; for A. platensis 100–800 µg mL−1) during 7 days. SOD activity increases significantly in Chlorella vulgaris and Arthrospira platensis at concentrations of 480 and 200 ug mL−1, respectively. Although there was no significant change in APX (ascorbate peroxidase) activity in C. vulgaris, the APX activity decreased at 400 and 600 µg mL−1 concentrations in A. platensis. While the GR (glutathione reductase) activity increased at 960 µg mL−1 concentration in C. vulgaris, it also showed increases at 100, 200 and 400 μg mL−1 concentrations, but it decreased at 600 µg mL−1 concentration in A. platensis. MDA (malondialdehyde) and proline amounts decreased only at the concentration of 960 µg mL−1, while H2O2 didn't change compared to control. Total MDA, H2O2 (hydrogen peroxide) and proline amounts did not show significant change compared to control. It is found that the effects of Bentagran on growth and antioxidant parameters are diverse at different concentrations and species, and this can be attributed to the different reactive oxygen species (ROS) production ability in these species.

Our study focused on investigating the possibilities of controlling the accumulation of carbohydrates in certain microalgae species (Arthrospira platensis Gomont, Chlorella vulgaris Beijer, and Dunaliella salina Teod) to determine their potential in biofuel production (biohydrogen). It was found that after the introduction of carbohydrates (0.05 g⋅L−1) into the nutrient medium, the growth rate of the microalgae biomass increased, and the accumulation of carbohydrates reached 41.1%, 47.9%, and 31.7% for Arthrospira platensis, Chlorella vulgaris, and Dunaliella salina, respectively. Chlorella vulgaris had the highest total carbohydrate content (a mixture of glucose, fructose, sucrose, and maltose, 16.97%) among the studied microalgae, while for Arthrospira platensis and Dunaliella salina, the accumulation of total carbohydrates was 9.59% and 8.68%, respectively. Thus, the introduction of carbohydrates into the nutrient medium can stimulate their accumulation in the microalgae biomass, an application of biofuel production (biohydrogen).
