Abstract. Research has been carried out on the use of nanocomposite of TiO2/activated carbon in reducing the quality parameters of palm oil liquid waste through the adsorption-photodegradation mechanism with DO (dissolved oxygen) parameters. Characterization of samples catalyst nanocomposite of TiO2 /activated carbon was used using Scanning Electron Microscopy (SEM-EDX) and DO parameters with variations in the mass percentage ratio of TiO2/activated carbon are namely (0.4:0.3), (0.6:0.4), (0.5:0.5), (0.4:0.6), and (0.7:0.3). SEM-EDX shows that TiO2 particles stick and spread unevenly on the surface of the activated carbon, and the ratio of the atomic mass of titanium to sample abundance is 0.25. Based on the analysis of DO of palm oil liquid waste using catalyst nanocomposite of TiO2 /activated carbon, it is known that the DO value of palm oil liquid waste increases with the increase in contact time of the TiO2/activated carbon sample with sunlight. This indicates that TiO2/activated carbon can degrade the presence of hazardous chemicals in palm oil liquid waste through the adsorption-photodegradation mechanism.

Application of a constrained mixture design for lipase production by Penicillium roqueforti ATCC 10110 under solid-state fermentation and using agro-industrial wastes as substrate

Solid state fermentation (SSF) simulates the natural conditions fungal growth, where the amount of water in the reaction medium must be restricted, thus limiting the use of liquid substrate. An analytical strategy to deal with this limitation is the design of blending with constraints. Thus, the objective of the work was to optimize two constrained waste mixtures for the production of lipase by Penicillium roqueforti ATCC 10110 under SSF, using different substrates that combine solid and liquid waste. For this, the best fermentation time was determined through a fermentative profile, afterwards a restricted-mix design with lower and upper limits of the components of mixture I (cocoa residue, solid palm oil residue and liquid palm oil residue) and II (cocoa residue, mango residue and palm oil residue liquid palm) was applied. By means of Pareto and contour graphs, the maximum production points of lipase in mixtures I (6.67 ± 0.34 U g−1) and II (6.87 ± 0.35 U g−1) were obtained. The restricted mixture design proved to be a promising tool in the production of lipase by P. roqueforti ATCC 10110 under SSF since the use of restrictions is useful when intending to combine solid and liquid residues in fermentation processes.
