main mechanisms during adsorptive process. Current studies state that beer yeast

adsorbs Cu and Pb from solution. The competitive results show that the adsorptive

quantity for one metal is significantly decreased due to the presence of other metal

ions, but the total capacity for binding heavy metals changes a little. It was referred

that ion exchange is one of the main mechanisms during adsorptive process [9].

Organization of Lipid-Based Biofuel Production with Waste Treatment

Using Oleaginous Bacteria

The oleaginous bacterium was used to produce lipid-based biofuels from organic

waste. The recent study was designed to isolate oleaginous bacteria capable of grow-

ing on food-processing waste to produce biofuels on a sustainable basis, and about 26

oleaginous bacteria were isolated from natural crude oils using Luria–Bertani (LB)

medium under nitrogen-deficient conditions. The GC-MS analysis confirmed the

capacity of 10 isolates to produce free fatty acids (FFAs), where oleic acid appeared
