Answer: The pond water is green and in most cases caused by algae. In the case of wastewater, even if the treated water meets the discharge standards, there will be swimming algae such as chlorella, which will make the water colored. ...
In this work, Microcystis aeruginosa (toxic cyanobacteria) and Chlorella pyrenoidosa (typical green algae) were chosen as model microalgae to verify this hypothesis. ...
In contrast, activated sludge treatment without PAC produced an effluent that significantly inhibited (>50%) (i) the bioluminescence by Photobacterium leiognathi (ToxScreen³ test kit), (ii) the photosynthesis by the green algae Chlorella vulgaris (LuminoTox SAPS test kit), and (iii) the particle ingestion by the crustacean Thamnocephalus ...
Algal monocultures (Chlorella sorokiniana and Botryococcus braunii) and algal communities native to clarifiers of a wastewater treatment plant were batch cultivated in (1) clarified effluent following a biochemical oxygen demand (BOD) removal reactor post-BOD removal clarified effluent (PBCE), (2) clarified effluent following a nitrification reactor post-nitrification clarified effluent (PNCE), ...
The present study examined the effects of metals to H. incongruens through aquatic and dietary exposures. The algal food Chlorella vulgaris was exposed to different concentrations of Cd, Cu and Zn and subcellular distributions of these metals in algal cells were determined. ...
Nine local dominant freshwater algal species, including green algae (Chlorella sp., Chlamydomonas sp. and Scenedesmus quadricauda), diatom (Navicula pelliculosa, Nitzschia palea Grunow and Synedra sp.), blue-green algae (Microcystis sp., Chroococcus sp. and Gloeocapsa sp.) were isolated from source water reservoirs and cultivated in the ...
Using an ion‐exchange based solid phase micro‐extraction (SPME) method, the freely dissolved concentrations of C12‐benzalkonium were measured in different toxicity assays, including i) immobilization of Daphnia magna in the presence/absence of dissolved humic acid; ii) mortality of Lumbriculus variegatus in the presence/absence of a suspension of OECD sediment iii) photosystem II inhibition of ...
The toxic effects of cadmium (Cd) on the green alga Chlorella vulgaris were investigated by following the response to Cd of various toxicity endpoints (cell growth, cell size, photochemical efficiency of PSII in the light or ФPSII, maximal photochemical efficiency or Fv/Fm, chlorophyll a fluorescence, esterase activity and cell viability). ...
Four green microalgae (Hydrodictyaceae reticulatum Lag, Scenedesmus obliquus, Oedogonium sp. and Chlorella pyrenoidosa) and three blue-green algae (Anabaena flos-aquae, Oscillatoria amoena Gom and Spirulina platensis) were used to remove the nutrients (N, P, C), especially ammonium nitrogen (NH4+-N), from diluted DPW with 300 mg/L algae ...
Thus, an efficient way to remove excess algae is needed in wastewater treatment. In this study, the potential of the filamentous cyanobacterium, Oscillatoria okeni, and the green alga, Chlorella vulgaris, to remove nitrate-nitrogen from tilapia-pond effluent was assessed. ...
The sorbents called 'AlgaSORB-sp' and 'AlgaSORB-ch' were derived from two different algae, viz., Spirogyra and Chlorella, respectively . The metal detection was made by differential pulse, anodic stripping voltammetry. The retention of 'labile' species onto biosorbents in dynamic mode at optimised conditions of pH 6.9 and flow rate 1.0 mL/min in AlgaSORB-sp ...
A comparative study between the nitrate reductase NR activity of green and blue green algae in presence of heavy metals is being conducted to present a situation where nitrate reductase process may be affected in presence of heavy metals. Metals interacted negatively with the nitrate reductase activity of a blue green alga, Anacystis nidulans and green ...
