Bioflocculant produced by Bacillus velezensis and its potential application in brewery wastewater treatment.

ABSTRACT: This study was designed to evaluate the potential of bioflocculant producing strains isolated from wastewater sludge. According to the Plackett-Burman design, the response surface revealed glucose, magnesium sulfate, and ammonium sulfate as critical media components of the nutritional source, whereas the central composite design affirmed an optimum concentration of the critical nutritional source as 16.0 g/l (glucose), 3.5 g/l magnesium sulfate heptahydrate (MgSO₄.7H₂O), and 1.6 g/l ammonium sulfate ( (NH₄)₂SO₄), yielding an optimal flocculation activity of 96.8%. Fourier Transformer Infrared Spectroscopy (FTIR) analysis confirmed the presence of hydroxyl, carboxyl and methoxyl in the structure of the bioflocculant. Additionally, chemi
