Valorisation of olive pomace by solid-state fermentation with Aspergillus speci...

Pollution by olive mill wastes is a crucial problem in Mediterranean area and their proper management and utilization is demanded. Olive pomace offers excellent properties to produce enzymes by solid-state fermentation (SSF) using filamentous fungi. Particularly for lipase production, since it has residual content of olive oil. The aim of this work was to optimize the production of lipase by Aspergillus ibericu...

Valorisation of vinasses by recovery tartaric acid and bioproduction of lactic ...

Management of agro-industrial wastes: utilization of exhausted grape mark as co...

The reutilization of biological wastes is of great interest since, due to legislation and environmental reasons, the industry is increasingly being forced to find an alternative use for its residues. Moreover, the use of these wastes considerably reduces the production costs. Olive oil and wine production are the most common food processing activities in the countries of southern Europe. Environmental pollution...

Influence of moisture content, temperature and inoculum size on lipase producti...

Pollution by olive mill wastes is a crucial problem in the Mediterranean area and proper management is necessary. Olive pomace, a solid by-product generated by the olive oil two phase extraction process, is an acidic and very humid material, rich in organic matter, potassium, nitrogen, carbohydrates, phenols and also contains residual fats, which make an interesting substrate for lipase production under solid-s...

Evaluation of substrate composition for lignocellulolytic enzymes production by...

Wastes from olive oil and wine industries (as exhausted grape mark, vineshoot trimmings, two-phase olive mill waste, vinasses and olive mill wastewater were evaluated for lignocellulolytic enzymes production (as cellulases, xylanases and feruloyl esterases) by solid state fermentation with Aspergillus niger, Aspergillus ibericus and Aspergillus japonicus. To study the effect of different substrates in enzymes p...

Extraction of ferulic acid from agro-industrial wastes and evaluation of biocon...

Several agro-industrial wastes (as chestnut and pistachio shells, grass, leaf fruit, vine leaf,and, red and white grape stems) were evaluated to ferulic acid extraction. The chemical analysis of these raw materials shows a high content of xylan in pistachio shells (33%), following the biorefinery concept, this fraction can be used in xylitol manufacture. The lignocellulosic materials were submitted to an alkali...
