In this study, the possibility of using proteins recovered from excess sludge as animal feed was investigated. The proteins were recovered through the processes of sludge disintegration (alkali treatment followed by ultra-sonication), preci...
Production of bioemulsifier by Bacillus subtilis, Alcaligenes faecalis and Enterobacter species in liquid culture [0.03%]
在液体培养基中利用芽孢杆菌、不动细菌及肠杆菌生产生物乳化剂
