This review deals with the possible applications to recycle fly ash from incineration plants.

The results of anaerobic digestion in a fluidized bed reactor fed with municipal wastewater enriched with glucose are presented.

The pyrolysis of Refuse Derived Fuel has been studied in this work by analyzing the gaseous product composition at different temperatures and reaction times.

Il presente lavoroo è finalizzato al trattamento dei residui provenienti dalla lavorazione degli agrumi nell'industria alimentare.

This work provides a picture of the problems od industrial safety and hygiene, environmental prevention, protection and impact related to biotechnological processes, with particular concern to the microbial production of citric acid.

The nacroscopic effects of mechanical mixing on the biological activities of Saccharomyces cerevisiae cells employed in batch fermentations of dilute starch hydrolysate solutions are studied.

A semi-empirical approach to scale-up problems, based on the experimental results obtained using reactors of increasing size, is presented in this work to predict the performance of industrial realizations.

Procedimento per reazioni biologiche a cellule immobilizzate su supporti e apparecchiatura per realizzarlo

Emplying a simulation technique of the diffusive process through biofilms with different thickness, phenol diffusion has been studied, and the diffusion coefficient has been evaluated in aqueous phase through a Pseudomonas putida biofilm.

A model has been proposed previously to describe the kinetics of ethanol fermentation in an entrapped cell column in the presence of sponge as cell support. That model has been improved to take into account product and substrate inhibition of the fermentation kinetics, as well as the simultaneous effects of CO2 bubble development and the...

An interesting system for the continuous fermentation and the simultaneous recovery of ethanol is presented in this paper.

The aimn of the present work is the performance evaluation of a fluidized bed reactor in the anaerobic treatment of a wastewater deriving from the washing operations of the wine industry.

Conferenza in cui il Prof. Marco Del Borghi ha presentato l'effetto del mescolamento sulla fermentazione alcoolica discontinua di una soluzione diluita di idrolizzato d'amido.

This work presents a modification of the A/O process for the removal of phosphorus from wastewater, which consists in alternating aerobic and anaerobic phases in the same reactor.

The results of fermentations carried out in the RBS reactor working in batch, in continuous with cell support, and in continuous without cell support have been presented in order to compare the different productivities and to assess the performance of the RBS immobilized cell reactor.

The airn of this work is the treatrnent of orange wastes coming frorn agricultiire activities of food industries. A set of batch alcohol ferrnentations of these residues has been done using different pretreatrnent operations devoted to process optirnization, arnong which filtration appears to assure, at the sarne time, the best fermentation...

The effects of mixing on batch alcohol fermentation of diluted solutions of starch hydrolysate is studied.

Aims of previous research works have been the improvement of the continuous fermentation and the recovery of useful resources from molasses by overcoming the inhibitions noted. This paper examines a method for doing so. It consists of a support regeneration procedure carried out by washing the reactor with a limpid sugar solution devoid of...

To investigate the effect of shear stress on alcoholic fermentation, a series of batch runs has been carried out at a constant rotation speed of the impeller (5 s-1) and using the same inoculum of fresh Saccharomyces cerevisiae cells, previously stressed in an isotonic solution without substrate for different application times 0-20 h).

The present paper deals with the study of the kinetics and thermodynamics of batch enzymic hydrolysis of multisubstrate media in the presence of more than one glucanase.

This article aims at deriving kinetic models for the Rotating Biological Surface reactor operating with and without cell porous support

Hydrogenolysis is one of the most promising innovating technologies because it allows the toxic organic chlorides to change quickly into their corresponding hydrocarbons, under moderate conditions.

A laboratory scaled set-up, consisting in a glass column, filled with a mixture of peat and glass beads and inoculated with a pure culture of Pseudomonas putida, has been employed as biological filter in this study to purify a waste gas contaminated with variable phenol concentrations.

The purpose of this study is to investigate the feasibility of biologically removing phenol from waste gases by means of a biofilter using a Pseudomonas putida strain.
