“…Researchers (Zhang et al, 2007) had earlier observed that enzymes responsible for bioflocculant production are activated for different microorganisms and substrates at an optimum temperature. Although many studies (Chen et al, 2016;Bukhari et al, 2018;Mohammed and Dagang, 2019) indicated optimum bioflocculant production at temperatures between 25°C and 37°C, The optimum production at 40°C in this study agrees with the report of Aljuboori et al (2013) who also reported highest at same temperature. Generally, polymer-specific synthesis enzymes such as hexokinase that convert glucose to glucose phosphate (phosphorylation), pyro-phosphorylases that convert sugar nucleotides and glycosyltransferases that transfer the nucleotides across the periplasmic membrane to form repeated units have been indicated to play vital role in bioflocculant synthesis (Agunbiade, 2017).…”

The biodegradable and non-toxic Bioflocculants have attracted considerable interest as alternative to non-biodegradable chemical flocculants. However, the cost of fermentation media for bioflocculant production and low flocculation efficiency is a major challenge. In this study, we grow Bacillus spp isolated from sediment of local clay pot on spoilt orange juice to produce bioflocculant. The culture supernatant of the bacilli grown on spoilt orange juice were screen for bioflocculant production using Jar test method and Kaolin clay suspension as model wastewater. The effect of pH and temperature on the bioflocculant production were also studied. The effect of cations on bioflocculation rate of the bioflocculant produced were tested via hybridization of the bioflocculant with the cations. The bioflocculation efficiency of the bioflocculant on sample wastewaters were also determined. The bacilli isolated initially had flocculation rate between 31.1±1.6 % to 76.4±1.2% when cultured on screening media. Bioflocculation rate peaked to 77.9% at 40 oC while the lowest flocculation rate (55.41%) was obtained at 25 oC. The optimum bioflocculant production (about 78%) was recorded at pH 6 – 7 while the highest bioflocculant production (84.2%) was achieved at 96th hour of incubation. Na+ and Fe3+ had serious inhibitory effect on the bioflocculant while K+, Ca2+, Mg2+ and Al3+ had less or no effect on the bioflocculant. The bioflocculant had up to 77.7% and 64.5 % on Kitchen wastewater and aquaculture wastewater. This study reveals the potential for utilization of spoilt orange juice as fermentable substrate for bioflocculant production especially if the fermentation conditions and flocculation parameters are well optimized.

“…Moreover, the high carbohydrate content affirmed our previous study that the bioflocculant is thermally stable [ 24 ]. Bioflocculants dominated by protein content are known to be heat sensitive as proteins denature easily at high temperatures [ 47 ]. Our findings are in agreement with observations found in other studies.…”

“…The bioflocculant showed the removal efficiencies of 73, 49, 47 and 50% for BOD, COD, P and N, respectively (Table 4). It is worth noting that the bioflocculant revealed the highest removal efficiencies than the conventional flocculants teste, FeCl 3 (27,36,46 and 40% for BOD, COD, P and N, respectively and alum (47,33,29 and 40% for BOD, COD, P and N, respectively) in all parameters (Table 7). The effectiveness of wastewater treatment is mostly conveyed in terms of reduction in the chemical oxygen demand (COD) and biological oxygen demand (BOD).…”

A variety of flocculants have been used to aggregate colloidal substances. However, recently, owing to the adverse effects and high costs of conventional flocculants, natural flocculants such as microbial flocculants are gaining attention. The aim of the study was to produce and characterize a bioflocculant from Pichia kudriavzevii MH545928.1 and apply it in wastewater treatment. A mixture of butanol and chloroform (5:2 v/v) was used to extract the bioflocculant. Phenol–sulphuric acid, Bradford and Carbazole assays were utilized for the identification of carbohydrates, proteins and uronic acid, respectively. Scanning electron microscopy (SEM) and elemental detector were employed to determine the surface morphology and elemental compositions. The removal efficiencies were 73%, 49% and 47% for BOD, COD and P, respectively. The bioflocculant (2.836 g/L) obtained showed the presence of carbohydrates (69%), protein (11%) and uronic acid (16%). The bioflocculant displayed a cumulus-like structure and the elemental composition of C (16.92%), N (1.03%), O (43:76%), Na (0.18%), Mg (0.40%), Al (0.80%), P (14.44%), S (1.48%), Cl (0.31%), K (0.34%) and Ca (20.35). It showed the removal efficiencies of 43% (COD), 64% (BOD), 73% (P) and 50% (N) in coal mine wastewater. This bioflocculant is potentially viable to be used in wastewater treatment.

“…The oil palm is capable of producing more oil per cultivated hectare than any other oil producing crop [5]. One drawback in the processing of palm oil is the large amount of water used, resulting in a large quantity of wastewater, commonly termed palm oil mill effluent (POME), which is produced in volumes three times that of the crude palm oil product itself [6]. POME contains a high organic content, and hence exhibits large values for biochemical and chemical oxygen demand, rendering it unsuitable for release into the environment without extensive treatment [6][7][8][9].…”
