“…For example, the addition of glycerine as a carbon source (v/v: 1/100) and (NH 4 )2SO 4 as nitrogen source (0.5 g l −1 ) to potato starch wastewater during the growth of Candida anglica allowed the production of bioflocculant with FA of 94.6%. Generally, the yeast extract increased the growth and the FA when added to formaldehyde wastewater, K-acid wastewater , H-acid wastewater (Zhong et al 2014a) and Chromotropic acid (Zhong et al 2014b). This effect could be explained by the presence in yeast extract of amino acids, inorganic nitrogen and growth factors (iron, calcium, magnesium, strontium, sodium, potassium, barium, manganese, copper, lead, aluminum and vanadium) at concentrations satisfying the nutritional requirements of microorganisms.…”

Various microbial strains (bacteria, fungi, and microalgae) produced polymers variable in composition (protein, cellulose, polysaccharide, etc) with interesting flocculation properties such as the ability to remove large spectrum of pollutants (organic and inorganic materials, etc) from wastewater and the stability over a wide range of temperature, pHs and salt concentrations. These bioflocculants have been characterized and successfully tested in wastewater treatment and sludge dewatering. The production of microbial bioflocculants involves the culture step of the bioflocculant-producing microorganism in an appropriate medium, followed by polymer extraction. The production processing is mostly controlled by the microbial growth medium cost. Agro-industrial wastes including agricultural by-products (rice hull, rice stover potato by-products, peanut hull, corn cob, wheat bran, etc), sugar processing wastes and fermentation liquors contain nutrients such as nitrogen and carbon, which can sustain the microbial growth and bioflocculant production. Recently, the potential use of wastewater and sludge as growth media for various bioflocculant-producing microorganisms has been demonstrated. Interestingly, waste pre-treatments may be essential to enhance the microbial growth and the bioflocculant production. Bioflocculant properties (polymer yield, polymer composition, flocculating activity, etc) are controlled by the growth conditions. Moreover, the produced materials showed acceptable results for wastewater treatment and sludge dewatering. This new strategy reported in this review can decrease to some extent the environmental problems related to the disposal of agro-industrial wastes and wastewater sludges. At the same time, this could reduce the cost of microbial bioflocculant production.

Bioflocculants are commonly used in wastewater treatment. In this study, an efficient bioflocculant-producing strain, Bacillus sp. R1, was isolated and identified; strain R1 could efficiently produce bioflocculant BF-R1 with wheat bran hydrolysate. The characteristics and flocculation mechanisms of BF-R1 were determined and it was then applied for the granular carbon particles treatment in wastewater. Notably, 3.71 g of BF-R1 were produced when 200 mL/L wheat bran hydrolysate was used as the sole carbon and nitrogen source. BF-R1 contained polysaccharides, proteins, and glycoproteins and showed a good flocculating efficiency of 91.00% for granular carbon particles in contaminated wastewater when 3.50 g/L BF-R1 was added, thus achieving successful recycling of fine particle-contaminated wastewater. Taken together, our findings for the first time demonstrate that BF-R1 fermented using WBH can probably be a promising candidate agent for wastewater management processes.

In the present research, bioflocculant was produced from Bacillus subtilis using molecular methods. The structural and functional features of the bioflocculant were determined that it consisted of 64% carbohydrate and 18% protein. Production medium for bioflocculant mainly comprised Sucrose 16 g; Peptone 2 g; MgSO 4 •7h 2 O 0.3 g were statistically optimized to increase the bioflocculant production. They were further characterized by Field emission scanning electron microscopy (FE-SEM), and Fouriertransform infrared spectroscopy (FTIR).Therefore, they could be considered as a suitable method for treating municipal wastewater based on high flocculating rate.
