Pollution and Global Warming

Microbial bioremediation covers a wide range of recalcitrant degradation of pharmaceutical waste. The present study aims to inspect the dried, nonliving Pleurotus florida bio-waste efficacy for bioremediation of aspirin in an ecofriendly manner. The equilibrium uptake of aspirin was investigated using batch experiments which were carried out as a function of contact time, initial concentration, pH and biomass dose. The optimal conditions for the highest percentage removal of aspirin was achieved at 2 h contact time, 100 mg/L of aspirin concentration, at pH 5 and 4.0 g/L biomass dose. The best fit was obtained by Langmuir isotherm model with high correlation coefficient (R2=0.989). The Pleurotus florida bio-waste was characterized using Fourier transform infrared spectroscopy, X-ray diffraction and thermo-gravimetric analyzer and their interaction between the aspirin was illustrated with Fourier transform infrared spectroscopy and scanning electron microscope.
