Application
- Bioflocculant produced by Bacillus velezensis and its potential application in brewery wastewater treatment.: This research explores the application of a bioflocculant produced by Bacillus velezensis, with magnesium sulfate heptahydrate as a potential flocculating agent in brewery wastewater treatment. The study highlights the efficacy of magnesium sulfate heptahydrate in enhancing flocculant performance, offering a cost-effective and eco-friendly solution for wastewater management in the beverage industry (Agunbiade et al., 2022).
