Abstract:
In this study, the use of non-sterile textile wastewater as a potential source for culture of green microalgae Golenkinia radiata (Chodat, 1894) and effects of the wastewater on the growth rate the microalgae was researched. The textile wastewater were added to the pre-prepared microalgae culture in obtained from four different units of the treatment plant. The trials were carried out with textile wastewater that were taken from raw wastewater (CE), equalization tank effluent (SE), active sludge effluent (ASE) and the effluent (E). BG11 medium was used as the control group (C). Trials were performed in 1 L bottles, and three replicates in a batch culture system for both sterile and non-sterile wastewater samples. The growth of the species was measured as Chl a and Chl b (mg/l) biomass and specific growth rates were calculated based on chlorophyll by monitoring the exponential growth phase. The highest specific growth rate was obtained from the SE (S) trial with 1.23 ± 0.83 day-1. According to the results obtained, G radiata species was not affected by changing in T, DO and pH and showed tolerance to variable conditions. Consequently, G radiata species may have the potential to be use both in bioremediation of textile wastewater, and as a biomass wastewater-fed in order to obtain biofuel in the future
