This article reportes a quantitative microbial investigation developed on a continuously-operating bench-scale biofilter treating styrene-polluted gases, filled with a mixture of peat and glass beads as packing medium, inoculated with the styrene-oxidizing strain Rhodococcus rhodochrous AL NCIMB 13259.

The combined effects of starting xylose concentration and specific oxygen mass flowrate on xylitol production from rice straw hydrolyzate by Debaryomyces hansenii were investigated using Response Surface Methodology.

The combined effects of initial xylitol supersaturation value (Xyts) and cooling temperature (Tc) on xylitol crystallization from synthetic solutions were investigated using response surface methodology. A 32 full-factorial design was employed for experimental design. Synthetic solutions were subjected to crystallization, aimed at contributing...

The aim of the present work was to optimise the oil extraction process of the Italian olive fruits of Coratina cultivar using a previously selected enzyme formulation.

Preliminary xylitol separation tests were carried out using solutions with relativity high concentrations of xylose and xylitol to simulate the actual composition of hemicellulose hydrolyzates.

The influence of oxygen transfer rate on vanillin production was investigated in this work using the recombinant strain Escherichia coli JM109pBB1.

The bio-oxidation of 2,3-butanediol to acetoin and diacetyl was studied exploiting the membrane-bound alcohol dehydrogenase activity of whole cells of Acetobacter hansenii MIM 2000/5, which previously proved very effective in the dehydrogenation of primary and secondary alcohols as well as diols.

Aim of the present work is the study of the bio-oxidation of 2,3-butanediol to diacetyl and acetoin, two compounds that can be used for the production of more complex flavours.

The present work deals with the development of an enzymatic treatment aiming at producing high-quality olive oil with increased phenolics content and antioxidant activity.

The Response Surface Methodology was applied to investigate the effect of the contact time between biomass and entrapping material as well as that of the immobilized biomass incubation time on subsequent vanillin production from ferulate by Escherichia coli JM109pBB1.

The aim of the present work was to evaluate a xylitol down-stream methodology combining low pressure evaporation and cooling.

Winemaking by-products present a high environmental impact due to their considerably high biochemical and chemical oxygen demands. This study is focused on the optimization of the traditional solvent extraction technology of phenols from Pinot Noir grape skins (Vitis vinifera). To such a purpose, the combined effects of the extraction time (9,...
