Evaluation of the flocculation potential and characterisation of a bioflocculant produced by activated sludge bacteria from Vulindlela Wastewater Treatment Plant
Biofflocculants are flocculating agents produced by microorganisms during their phase of growth as secondary metabolites. These bioflocculants play an important role in wastewater treatment and industrial applications. This study aimed to isolate, screen and identify bioflocculant …

Characterization of bioflocculant produced by Proteus mirabilis PJC12 isolated from Tendele coal mine wastewater and its application.
… are conventionally used because of their high flocculating activity, low-cost production and availability. However, synthetic flocculants have been reported to have negative impacts on the environment and have caused some serious health problems including neurotoxicity and cancer-genic to …

Biosynthesis of copper nanoparticles using a bioflocculant from Alcaligenis faecalis, characterization and its application
… copper nanoparticles were shown to have higher flocculating activity and removal efficiency of both BOD and COD when compared with the bioflocculant and commercial flocculant. Moreover, the potential of CuNPs was also observed when compared to the bioflocculant and iron chloride in kaolin clay, …

Production and characterisation of bioflocculant produced by bacterial isolates from Richards Bay harbour, Kwazulu Natal
… method. Among the identified isolates, one with flocculating activity above 70% was used for bioflocculant production. Bacillus atrophaeus culture conditions were optimised for improved flocculating activity as well as the production yield. To obtain an optimum culture medium condition, the …

Green synthesis and characterisation of metal-based nanoparticles using Kombucha tea SCOBY yeast-based bioflocculant and their application in wastewater treatment
… SEM-EDX, UV-Vis spectroscopy, TEM, and TGA. The flocculating activity of both the bioflocculant and the bio-synthesized nanoparticles was investigated, with subsequent optimization of dosage size, temperature, pH, metal ions, and shaking speed. Additionally, the study assessed the antimicrobial …

Synthesis and application of a grafted flocculant produced from a chemical combination of a bioflocculant TKT and acrylamide (AM)
… bioflocculant. The effect of dosage size on flocculating activity was evaluated. The pH and thermal stability of TKT-g-PAM were assessed spectrophotometrically. The removal efficiencies of TKT-g-PAM on chemical oxygen demand (COD), biological oxygen demand (BOD), nitrogen and sulfur on …

Synthesis, characterization and application of polyacrylamide grafted bioflocculants (TMT-1-g-PAM 2 and TST-1-g-PAM 3)
… were also screened for antibacterial activity, using micro-dilution assay. Their biodegradation was investigated by a composting method. The effects of dosage size, cations, pH, temperature and salinity on the flocculating activities of the grafted bioflocculants were also evaluated, …

Characterization of selected microbial species for bioflocculant producing potential and comparison with traditional flocculants in industrial waste water treatment
… are conventionally used due to their high flocculating efficiency and availability. However, their applications result in serious health problems such as cancerogenicity and neurotoxiciy. Consequently, bioflocculants appear to be an attractive alternative to synthetic flocculants because …
