“…Since EDTA is the most common chelating agent used for desorption of metals, its application in the present study was 30% less than the percentage evaluated by Zinicovscaia et al [28] with HCl, HNO 3 , CH 3 COOH and NaOH. The heavy metals present in wastewater may be recovered from biomass by the process of electrolysis and desorption of the sorbent [29].…”

Nickel (Ni) leftovers arise from both catalyst application interventions and Ni alloy piping of the cooking oil industry (COI) being wasted as pollutants of freshwater bodies via discharged effluent. The current study assessed one of the indigenously feasible Ni removal systems comprising autochthonous Arthrospira platensis Gomont (AP)-driven Ni phycoremediation cells (NPCs). After screening AP for hyperaccumulation in the Ni spiked solution, AP was transferred to the NPCs. Propagation of the AP inoculum was proportionate to the pollution load drop of COI with 22.97 and 55.07% drops in the biochemical (BOD) and chemical oxygen demand (COD), respectively. With the 0.11 bioconcentration factor, there was an uptake of 14.24 g mineral with 16.22% Ni removal and a 36.35 desorption ratio. The experimental data closely fitted with the Langmuir and Freundlich isotherms, respectively. The study concluded that A. platensis could be taken for treatment of Ni-loaded industrial effluents at the microcosmic level.

“…The two samples under the microscope appear as a filamentous cyanobacterium; when classified the Bactria morphological from reference [37], it shows that the strain is Oscillatoria (9 strains are contained within this genus) PCC 7105 Fig. (17). The variation of the chlorophyll saturation was because of the white and yellow LED used in the incubation phase, which will be taken into the stage of designing the PBR.…”

Biodesalination, using photosynthetic species of bacteria to exclude NaCl ions from seawater could provide sustainable new saline water desalination methods associated with available methods. 90% of salts can be removed by Cyanobacteria and without pressures or external power source. This research aims to isolate and cultivate Cyanobacteria Oscillatoriales (O. sp.) to use in the biodesalination and reduction of total dissolved solids in seawater under the Egyptian condition and use isolated strain at an advanced level which is designing photobioreactor as a stage for biotreatment and use treated water in irrigation. Parameters presented in this paper include the growth rate of (O. sp.), Total Dissolved solids (TDS), pH, Oxidation reduction potential (ORP) and NH4 concentration. The results showed salt reduction ranged from 3 to 4 g.l -1 , and NH4 concentration increased up to 6.5 mg.l -1 and more than 9.99 mg.l -1 . The ORP decreased to about 129 mv. This result is achieved from 30 to 40 g of cyanobacteria biomass.

Human activities more and more intensify the pollution of aquatic ecosystems. These pollutants lead to some Cyanobacteria proliferation causing “blooms” or “efflorescence” and disappearance of sensitive species. The aim of the study was to determine the composition and variation of Cyanobacteria community in some polluted wetlands of Nkwen in Bamenda. Sampling of Cyanobacteria took place from October 2022 to September 2023 by using plankton net for phytoplankton and scrubbing for periphyton. Some hydromorphological and physicochemical parameters of water were measured in situ and in the laboratory. Results showed that species richness of microalgae amounted to 11 families divided into 22 genera and 46 species. Oscillatoriaceae constituted the most important family (26.66% with 12 species) of the Cyanobacteria community, in the study sites. Shannon-Weaver’s index was weak and varied between 1.24 (site 6) and 2.65 (site 2). These results showed that wetlands of Nkwen had a Cyanobacteria community more abundant where the water velocity is low, with high nitrates and phosphates contents. Different Cyanobacteria families with strong proliferation in polluted waters (sites 1, 2 and 3) were: Oscillatoriaceae, Gloeotrichiaceae, Rivulariaceae, Nostocaceae, Merismopediaceae, Microcoleaceae, Microcystaceae and Tolypotrichaceae. On the other hand, the families abundantly present in less polluted waters (sites 4, 5 and 6) were: Chroococcaceae, Pseudanabaenaceae and Aphanizomenonaceae. Thus, physicochemical parameters have an influence on the composition and structure of Cyanobacteria community in wetlands of Nkwen in Bamenda. Monitoring, based on biological indices of Cyanobacteria, could be developed to prevent the risks of perturbation of these wetlands.
