He is also Founder of the Intestinfo care network which is dedicated to IBD, and Founding Director of the Thematic Center for Research and Care in Lille: IBD Research Center.

Professor Pierre Desreumaux is an international specialist in Chronic Inflammatory Bowel Diseases (IBD) and his work earned him the Inserm Research Prize in 2005.


Project with KitoZyme

Professor Pierre Desreumaux’s project with KitoZyme aims to highlight the anti-inflammatory and/or analgesic properties of two ingredients developed by KitoZyme (chitosan and chitin-glucan from Aspergillus niger) on experimental models of colitis and intestinal nociception. In order to realize this, two pilot preclinical studies (animal experiments) will be conducted in collaboration with intestinal biotech development with a view to evaluating the effect of these ingredients and elucidating their mechanism(s) of action.

Full Professor at the Université Catholique de Louvain (UCL) in Brussels, Belgium Nathalie Delzenne is also a lecturer in Nutrition Biochemistry and Metabolism and President of the Metabolism and Nutrition Research Group at the Louvain Drug Research Institute within UCL.

Nathalie Delzenne is involved in several international scientific committees as President of the Belgian Nutrition Society, Editor for the Current Opinion in Clinical Nutrition and Metabolism, as well as Member of the Scientific Board of the European Society for Enteral and Parenteral Nutrition. Meanwhile, she was also a former member of the Board of Directors of the International Scientific Association for Probiotics and Prebiotics.

After obtaining a PhD in Pharmaceutical sciences in 1991 and a post-doctoral certificate in Nutrition (Lausanne, CH), she performed post-doctoral research related to nutrient-gene interactions (Paris Inserm Unit 342).

Following this, Nathalie Delzenne returned to the Université Catholique de Louvain, where she started an academic career. She pioneered the discovery of nutrients (prebiotics) and the importance of their role in controlling malnutrition (obesity, cachexia, polyunsaturated fatty acid deficiencies, etc.) and similar metabolic disorders.

She has published as either first or last author more than 250 papers and she currently leads several international projects that are focused on nutrition and health. Nathalie Delzenne is also President of the Louvain Drug Research institute.


Projects with KitoZyme


The Adipostop project aims at developing a synergistic and innovative combination of ingredients to fight against the development of cardiovascular diseases. The nutritional approach is oriented towards emerging cardiovascular risk factors and the relationships that may exist between the modulation of gut microbiota and the prevention of cardiovascular diseases.


The FiberTAG project will establish a set of biomarkers for dietary fiber binding (DF) and the gut-microbiota related health effect. We are aiming to refine the concept of DF based on microbiota-nutrient interaction by using existing cohorts and developing innovative approaches to evaluate insoluble DF.

Vincent Gerbaux

Oenologist Microbiologist

Vincent Gerbaux is in charge of the IFV project "Technoferm" Vincent Gerbaux is an Oenologist Microbiologist. In 1985, he joined the ITV (Technical Institute of Vine and Wine, now called IFV French Institute of Vine and Wine). Three years later he joined Burgundy.

Vincent Gerbaux is in charge of the IFV project named “Technoferm” and gathers studies regarding the control of fermentations (alcoholic and malolactic) and the control of microbiological alterations. His work on lactic acid bacteria and yeasts has led to the development, in partnership with producers, of original biomass, which is now offered to the viticultural profession.


Project with KitoZyme

At the same time, the work on the alterations has made it possible, in particular, to better understand the yeast Brettanomyces and to study new methods for enumeration in wines (flow cytometry) and for cell proliferation control. As such, chitosan is an alternative or a possible complement to the use of the classic and highly discussed sulfiting.

He is author of more than 300 publications and communications An Oenologist from the Pharmacy Faculty of Montpellier in 1989 and Doctor of the University Montpellier 1, he was Doctor associate of the University of California, Davis – USA in the department of Enology and Viticulture in 1993 and 1994.

Pierre-Louis Tesseidre is Full Professor at the Institute of Vines and Wines Sciences (ISVV) of the University of Bordeaux and was Adjunct Director of the UMR 1219 Œnologie INRA (Mixed Research Unit) with the responsibility of the Oenopro Group; he is actually directing the applied Chemistry Laboratory of the USC 1366 Oenologie. Pierre-Louis TEISSEDRE is an expert in the group of Technology and is the Scientific Secretary of the Commission «Safety and Health» of the International Wines and Vines Organization (OIV). He is also the Director of the Oenoviti international network (which comprises 55 partners) and Head of the National Oenologist Diploma, Master Erasmus Mundus Wintour as well as Foreign Office in ISVV. He is Rector of the French National Oenologist Union and specializes in the research field of grapes and wines phenolic compounds: qualitative, sensorial and physiological, analytical chemistry of grape and wine, wine quality during winemaking and ageing, food safety (contaminants) and health in the science of oenology. Pierre-Louis TEISSEDRE has developed many scientific collaborations at both industrial and academic levels. He is author of more than 300 publications and communications in international journals with peer reviews and is co-inventor of 11 patents.

Project with KitoZyme

The various research projects carried out by KitoZyme and Pr. Tesseidre have led to a number of different inventions and patents:

1) Cell wall derivatives, their preparation process, and use thereof scope: this covers the processes for obtaining chitosan from fungal sources.

2) The use of polysaccharides of fungal origin as a pharmaceutical composition or food supplements for human or animal health scope: this covers the use of chitin-glucan for the manufacture of an oral composition, in particular in order to obtain a positive effect on health.

Marco Ventura is Associate Professor at the University of Parma, Italy. Professor of General Microbiology, Laboratory of Probiogenomics, Department of Life Sciences, University of Parma, Italy

In 2003, Marco Ventura received his PhD in Natural Sciences from the Swiss Federal Institute of Technology (ETH) Zurich, Switzerland. He subsequently performed postdoctoral research work at the Dept. of Microbiology, National University of Ireland, Cork (Ireland) before joining the faculty at the University of Parma in 2005.

His research is focused on the molecular analysis of bifidobacteria, as well as the diversity and host significance of the gut microbiota.

Project with KitoZyme

This has involved the evaluation of the potential prebiotic features of chitin-glucan toward bifidobacteria under in vitro conditions, the identification of the genetic arsenal involved in the metabolism of chitin-glucan by bifidobacteria and the identification of the prebiotic features of chitin-glucan toward bifidobacteria under in vivo conditions in a murine/rat model.
