Partial characterization of biosurfactant from Lactobacillus pentosus and compa...

The capability of a cell bound biosurfactant produced by Lactobacillus pentosus, to accelerate the bioremediation of a hydrocarbon-contaminated soil, was compared with a synthetic anionic surfactant (sodium dodecyl sulphate SDS-). The biosurfactant produced by the bacteria was analyzed by Fourier transform infrared spectroscopy (FTIR) that clearly indicates the presence of OH and NH groups, C=O stretching of ca...

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

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...
