The mechanism of catechol oxidation by soil metal oxides is investigated in a slurry reactor. This abiotic transformation is shown to consist in a three-step process. The first step is a heterogeneous reaction. Catechol undergoes fast, partial oxidat

Olive mill wastewaters (OMW) are endowed with micro- and phyto-toxicity bound to the high polyphenol content. This work focuses on the potentiality of agricultural soil as a natural catalyst to promote polyphenol oxidation and polymerisation and thus

Lactate esters are increasingly used in food, cosmetic and pharmaceutical formulations due to their hygroscopic, emulsifying and exfoliating properties. The lipase-catalysed synthesis of butyl lactate by transesterification was investigated, in order

The phenol oxidase activity of green olive drupae was characterised in view of possible applications for the de-phenolisation of polluted waters. For experimental convenience, activity measurements were performed on acetone powders and raw-extracts f

The lipase-catalysed synthesis of geranyl caproate has been carried out in a stirred batch reactor. A continuous flow of nitrogen is provided. The gas is pre-equilibrated by bubbling within different vessels upstream from the reactor, in order to ins

Aircraft de-icing fluids (ADF) are a source of water and soil pollution in airport sites. Propylene glycol (PG) is a main component in several commercial formulations of ADFs. Even though PG is biodegradable in soil, seasonal overloads may result in

The thermostability of anhydrous α-chymotrypsin has been analysed both in air and in organic solvents, with regard to the effect of the protein water-content on the course of deactivation. A higher initial water content increases the rate of inactiv
