Genetic and chemical analyzes of transformations in compost compounds during biodegradation of oiled bleaching earth with waste sludge

► Paper sheds light on the behavior of microorganisms in degradation of fats waste. ► The main finding is that a consortium of degraders remains unstable in composting. ► Biodegradation is involved by emulsifying properties of higher fatty acids. ► Microorganisms did not synthesis of surfactants in natural conditions.
