Klebsiena pneumoniae H12 produced a newly identified extracellular po}ysaccharide in an ethanol medium with a yield of 3.0 g/1. The molar compesition of the polysaccharide was 56.04% galactose, 25.92% glucose, 10.92% galacturonic acid, 3.71% mannose, and 3.37% glucuronic acid. The addition of O.5%-1.5% NaCl increased production. The polysaccharide flocculated with kaolin clay in silspension at ...

Harvesting impacts the costs of microalgae production and affects characteristics final product. Therefore, this study evaluated Moringa oleifera seed powder (MP) as a bioflocculant compared to two chemicals (Aluminium Sulphate—AS Iron Chloride—IC) harvest mixed culture (Chlorella vulgaris Desmodesmus sp.) grown on digestate. MP was most stable flocculant but resulted in lowest harvesting effic...

Attention has been paid to bioflocculants production because of their effectiveness, innocuousness and environmental friendliness. This study aimed characterise a bioflocculant from Bacillus megaterium BMBF apply it in wastewater treatment. The proteins, carbohydrates uronic acid were calculated using the Bradford, phenol–sulphuric carbazole assays, respectively. An energy-dispersive X-ray (EDX...
